Chuck Peddle

This snippet I grabbed last year as I was compiling my Commodore 8-bit write up for Vintage Computer Festival 1.0 at least it's a lead... (my scrapbook doesn't get cleaned much) I think it was a writeup on an awards ceremony for the innovators of the microcomputer industry. > One of the awards went to William D. Mensch, Jr., president and CEO, The Western > Design Center Inc. Mensch was fundamental to the development of the Motorola > 68000 microprocessor, and he went on to help invent and develop the 6502 chip at > MOS Technology in the early 1970s. The 6502 was eventually used in Apple, > Commodore and Atari computers. > > The second award in the category was presented to Chuck Peddle, president, Thstyme > Ltd., and another MOS Technology veteran.

Guess you just have to follow the old "buy be ware". Yes, or at least there are some hints. First, the type of platic film is changing constantly (but you need a bit experiance, since not only the material is different over time, also for example, at the same time, companies in Europe liked different material than those in the US). Second the aging is visible thru the consistence. While the years it gets harder and harder. Even if you get the same material as uses when original, it takes some years to get the softener out. And third: In a lot of cases there are stickers on top. If you rewarp the card you loose them. And most visible, forth: if you juse it there will be dust on the card and traces on the books. I always try to keep original packt items as they are, althru I have some early singleboarders (i.e. 6800), where I have to fight myself every time I see them :) Gruss H. -- Ich denke, also bin ich, also gut HRK

If you're plugging the composite monitor into the RCA plug on the back of the C64 you're not going to have much luck. That's the RF output. The composite video is, if I remember correctly, on pin 4 of the AV DIN socket. The C64 does not have an internal speaker. Sound is modulated on the RF if you connect it to a TV, otherwise it's present on pin 3 of the AV DIN connector. Either way, ^G does *not* give you a beep on a C64. To get sound out of it you need to resort to POKEing (I can't remember exactly where you need to POKE, but I'm sure someone else on the list can).

VIC-20 -- no sound

by roblwill＠usaor.net

Try taking the output of the VIC through the inputs of a VCR. I'm not sure about this, but if I remember the monitor that was with my C64, there were two audio, and two video jacks, or a special cable that would combine everything into one plug. There was also another cable that would allow the computer to connect to a TV (had a converter and Audio/Video in one RCA jack, like a Nintendo). However, I no longer have the computer, so I can't be sure, but I do remember the four RCA jacks and the single multi-plug on the back of the monitor. There was also a switch to change from 60-75Hz (I think). The monitor would NOT work with a standard composite computer, such as an apple. -- -Jason (roblwill(a)usaor.net) ICQ#-1730318 ---------- > From: Marion Bates <Marion.Bates(a)Dartmouth.EDU> > To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> > Subject: Re: VIC-20 -- no sound > Date: Thursday, September 10, 1998 6:55 PM > > They didn't, so I made one to match your description here.

There's been an anomaly with the C64 for as long as I can remember, which is that when I use the video cable (the one that splits into three RCA's, one for video and two for sound) with the video-in jacks on the TV, I get a nice, sharp, black and white display, no color. If I use the composite port and a TV/game modulator box, I get (cruddy) color.

Microsoft assimilates Linux

At 09:37 PM 9/9/98 -0500, Doug Yowza wrote: > >Note the smiley. I liked it, though. It's almost believable. You can >construct an entire alternate reality on this kind of stuff. I recently saw a web site with dozens of fake press releases like this one about TeX. Some were funny, many were not. I forget where it was, and my bookmarks aren't telling. >What do you think it would take for Linus to sell out? Sell out? To me, the more interesting prospect is that there's no reason to buy him out, or anyone else out. For that matter, he may have already sold out; see below. I've been cultivating a pet theory lately regarding the assimilation of Linux by Microsoft. I believe it would be possible to refine a layer of compatibility into WinNT that would allow more and more Linux software to be recompiled to run under WinNT as-is (or someday, even running the executables directly.) I like tossing this idea on the table at programmer lunches just to see the reactions it provokes. Because of the freeware nature of Linux, as long as Microsoft abides by the rules of releasing the *relevant* source code, they'd be free to assimilate as many freeware tools as they like. Today they'll ship you a service pack CD for $9.95; tomorrow they might ship a $9.95 Linux compatibility CD, or even give it away as a promotion. The average Linux-head has a hypocritical hatred of Microsoft when considered in the light of their devotion to portable, run-everywhere source code. Why shouldn't Linux freeware run under NT, too? Of course, Linux is many different components. The bulk of it, as Richard Stallman tries hard to remind us, is based on GNU tools. Linus made the kernel, and hordes of programmers have refined the drivers and many other parts. For a while, there's been a project to make a Unix compatibility layer for GNU tools, at <http://www.cygnus.com/misc/gnu-win32/>. Steve Chamberlain <sac(a)transmeta.com> was the original author of this CygWin32 software. Note the e-mail address - Transmeta, Silicon Valley's mystery company of the moment. Oh, that's where Linus works now, too. Speculation about Transmeta includes the development of graphics chips and emulator chips that mimic various CPUs and OSes. When I present this possibility to Linux-heads, their first reaction is a fearful "But why would Microsoft want to do that?" I respond, "To run all that great Linux application software," a double-whammy that underscores the lack of anything truly comparable to Microsoft Office in the Linux market. To ask why Microsoft would assimilate Linux forces one to consider which Linux apps are most useful to anyone but the most nerdy. Do we really need to reproduce the kernel? WinNT already has a microkernel architecture that, in theory, allows different OSes to be placed on top - that's how Win32, OS/2, POSIX and DOS/Win16 live there. See <http://www.sysinternals.com/ntdll.htm> and other pages there for a nice discussion of this. Implement a layer of HAL that talks to Unix-style device drivers, add an X Window server to the top layers, expand the present POSIX support, enhance the GNU Win32 effort, make a more Unix-like shell, and presto, Microsoft assimilates a great deal of Linux. All the Linux programmers are working for Microsoft, unless they explicitly do something to prevent it. Think I can sell the idea to Uncle Bill, or do you think he's already Microserfs working on it? And perhaps even Ballmer is thinking about it: <http://www.zdnet.com/zdnn/stories/zdnn_smgraph_display/0,3441,2134010,00.ht ml> Freedows is an interesting effort to run Windows apps under Linux: <http://www.freedows.org/english/high/index.html>. As for the ten-year-rule, I think the assimilation of Linux into WinNT will be good for emulators in general, making it possible to download old Apple II executables and double-click on them and automagically start the right emulator. - John

Microsoft buys TeX :-)

by yowza＠yowza.com

MICROSOFT BUYS TEX, PLANS NEW PRODUCTS STANFORD PROFESSOR REAPS WINDFALL PALO ALTO, CALIFORNIA, USA (CNEWS/MSNBC) --- In a major move into the scientific publishing market, Microsoft Corporation announced today that it has purchased all rights to the computer language and document compiler known as TeX (pronounced, "tech"), and plans a major new product line based on the 20-year-old software. Stanford Professor Donald Knuth (pronounced, "kah-nooth"), the author of the widely-used TeX software, in a joint press conference at the university campus with Microsoft Chairman Bill Gates, acknowledged that the two had been negotiating for some months. "I felt that two decades of TeX in the public domain was enough. I am reasserting the copyright to my original work in TeX. Microsoft will carry the ball now, and I can get back to my computer science research." Knuth acknowledged he was paid a "seven-figure sum" from Microsoft, which he will use to finance his work on a project he has code-named "Volume 4". At the press conference, Microsoft chairman Bill Gates said the acquisition was "the kind of cooperation between academia and industry that builds prosperity for both." He added that TeX would "finally give Microsoft a foothold in mathematical desktop publishing" that has eluded the software giant since its founding. Drawing gasps of surprise from the college audience, Gates asserted that "TeX will soon be biggest jewel in the Microsoft crown." Apparently the jewel metaphor will include a hefty, unavoidable price tag for future TeX users. Gates outlined plans whereby all existing TeX compilers would be phased out, to be replaced by a new Microsoft master implementation written in C++. Beta versions for public testing on Windows 95 and NT platforms are expected in late 1998, issuing from a new 205-programmer project laboratory at Microsoft's Redmond campus. Microsoft TeX for other platforms, such as Unix workstations, will follow at an as-yet unspecified date. According to Gates, "the master TeX from Microsoft will ensure that the incompatibilities across platforms are once and for all eliminated." TeX software is widely used due its portability, although variations among operating systems have been troublesome due to uncoordinated development. Unlike the technical aspects of the project, Gates explained that pricing for Microsoft TeX has already been firmly set. The single-user retail product is expected to have a street price of about $600 and consist of three CDs. When heckled by an graduate student complaining about a high price for a formerly free product, Gates seemed startled, explaining that a "student edition at $299 is likely" and that "Microsoft will use the revenue to make TeX better." Most current users of TeX have paid nothing for their implementations, derived from Professor Knuth's formerly-free work. Before leaving the podium, Gates made a final comment that "TeX hasn't changed in years. What kind of a product can that be?", and then handed the microphone to an assistant, introduced only as the project leader for Microsoft TeX. The assistant displayed an overhead presentation using the current test version of Microsoft TeX. Equations and tables could be seen dissolving into each other in a morphing action between frames. "No one has ever done that with TeX," Gates announced from an audience seat at one point. "It's the kind of sizzle that can really enliven a dull paper at an academic conference." Some onlookers were not convinced, especially when the program crashed midway through the demonstration, resulting in a five-minute delay while Windows 95 was restarted. Microsoft technicians later blamed a third-party display driver. The impact on the large base of existing TeX users was unclear. During a question-and-answer period, Gates said that the "TeX" trademark would be registered as the exclusive property of Microsoft, and could not appear in any competitive or free software. "We are granting of our own good will until the 3rd quarter of 1998, free use to any existing TeX vendors or public-domain authors. That's plenty of time for an orderly phase-out and change-over to Microsoft TeX, or no TeX at all. After that, our legal department will be contacting them." A Microsoft attorney added that some of the project personnel would be dedicated to searching the Internet to find non-Microsoft TeX software. "Archives and collections of TeX-related programs will not be permitted. The standards must be enforced, or they become meaningless. We are rescuing a fine piece of work from being diluted into worthlessness. You would not believe the number of programs that have been based on TeX without any central, controlling authority. We will stop this infringement." Some large organizations dependent on TeX were stunned by the announcment and had not yet formed plans for dealing with the change. At the American Mathematical Society, whose publications largely depend on TeX for typesetting, editor Barbara Beeton was incensed. "I can't believe Don [Professor Donald Knuth] sold us out like this. We should have never based a publishing enterprise of this scope on so-called public-domain software. What were we thinking?" Publication schedules for the rest of 1998 were on hold, and journal editors scrambled to reassure their authors that deadlines would not slip more than a few months. Certain small businesses are also expected to feel the impact of the Microsoft ownership of TeX. Palo Alto restaurant owner Wu Chen appeared unhappy at the news, stating that "for ten year I print new menu every day with TeX, now I will pay big time." He displayed a crumpled, grease-spotted take-out flyer, and with tears in his eyes explained how multiple columns, exotic typefaces, and daily price changes could all be printed by TeX in a multi-lingual format. "In Wordperfect this would be a long journey." Commercial vendors of TeX software stand to lose everything in the face of the new Microsoft monopoly. While most derivatives of TeX were freely published, several companies had made a business of publishing proprietary versions. One anonymous source from a leading TeX firm said that "publishing TeX was a gold mine while it lasted, and the Internet let us mine it deeper and deeper. Now this is a cave-in right on our heads. TeX was a monumental work of beauty and utility, freely given to the world by one of the finest and most generous minds of the 20th century. Now it belongs to a lucky dropout. We're finished."

Microsoft assimilates Linux

by thomas100＠home.com

Hi, Well, Microsoft has been in the Unix camp before, with Xenix and SCO. [Witness my Trs-80 Mod 16 runs it]. But speculation aside, Apple is the one gobbling up both Unix and [Windows application functionality] into their new OS. That's scary in a very comfortable way. The old NeXT underpinnings with Linux innovation, etc. is turning out to be ultra-powerful! Thomas

Help needed with PDP-11/35 and XXDP problem

by gooi＠oce.nl

Hello readers. I have two questions which are in a sense related. I have a problem with my PDP-11/35 and withn XXDP+. When I boot my 11/35 it reports RT11-SJ (S) V04.00E. This version runs perfectly. When I try to boot RT11-FB V5.4 the VIRTUAL LED on the console goes on and at that moment the system hangs. I did check all the required jumper changes on the other CPU boards but the memory management unit M7238 was already installed in the system and the jumpers all seem to be correctly set. Anyway, when I boot that RT11-FB version on my PDP-11/34 it runs just fine. Needless to say that both are _real_ machines. When that RT11 version is booted on the 11/35 the ADDRESS LEDs show 076602 and the DATA LEDs show 177620. The MMU occupies address range 777600-777676. Is this a coincidence ? Last week I got the RL02 drives connected to the 11/35. I have a pack with XXDP+ on it and I hoped to run the diagnostics for the CPU and the MMU. When I have XXDP+ booted (that goes well) and enter the command "R BKTGD1.BIC" the READY light and on the 11/35 the ADDR and DATA LEDs blink a few seconds but then the system hangs. ADDR LEDs show 001156, DATA shows 000767. On the console terminal is the text "KT11-D EXERCISER DBKTG-D". Does anybody have any clues on how to proceed? How do I use XXDP, any manual anywhere ? TIA, Henk Gooijen gooi(a)oce.nl

WTB: Apple // (I think)

by roblwill＠usaor.net

Hello. Please forgive me if I mess up on any model numbers or names here. I'm not all that familiar with Apple computers. I'm looking for an old Apple // (?) - The small portable type. I'm looking for the older model with the 5.25" built-in disk drive (external p/s). I'm looking for the type with the LCD display. If you have one without one, let me know anyway. I don't want to pay all that much for one (w/o LCD), because they're fairly common (my school probably has about 20 on each floor, but they don't want to get rid of any of them). I need it to replace an old Franklin Ace 1200 that's a little too big for the limited space that I have. All I'm basically looking for is the main computer. I'm not looking for any manuals, disks, monitors (unless it's LCD), or anything like that. I'll I'm asking is that it works (I have a monitor). As for the Franklin, if anyone's interested in it, make me an offer (+shipping). It's an Apple ][+ compatible w/dual built-in 5.25" disk drives, 80-column and 40-column card, joystick, Amdek 13" color composite monitor, Original system disks, AppleWorks, and all the manuals. The computer works great, but it's just too big. You can see what it looks like at: <http://www.ncsc.dni.us/fun/user/tcc/cmuseum/ace.htm> It's not a very good picture, but it is the same unit that I have. The printer card, however has been switched in mine (I think), and was used with a Star Gemini 10-X printer (until it died). I'll also include the printer cable (connects to Centronics -standard printer). The version of AppleWorks also takes care of the missing open and closed-apple keys. -- -Jason (roblwill(a)usaor.net) ICQ#-1730318

Microsoft buys TeX :-)

by SUPRDAVE＠aol.com

In response to bill's final comment about, "what kind of product can that be?" hmmm, perhaps a less buggy and workable product? david In a message dated 9/9/98 9:50:25 PM Eastern Daylight Time, yowza(a)yowza.com writes: << Most current users of TeX have paid nothing for their implementations, derived from Professor Knuth's formerly-free work.

How did DC Unit on PDP11 work??

by rcini＠email.msn.com

I was thinking about this the other night {it was a slow night :-)} -- how does the DC option on the PDP-11 work (besides the obvious)? My 11/34 has a DC light on the panel, but I know that my unit did not come with a battery backup unit. What was involved with the DC option? Was it a special PSU and batteries? Or was it a board and separate UPS? Just curious...

I bought it through the school when Lego discontinued the kits last year. The system is based on Logo. The motors and sensors connect to the external interface box, which is connected to the Apple IIe via a 20 pin ribbon cable and interface card (which I think is really just a scaled down serial card). There are touch sensors, optosensors, motors, and lights for the kit. I currently have mine set up around my 9v Lego train, using the sensors to detect when it passes, the motors to raise and lower the crossing gates. There's nothing better than mixing computers and Lego! Tom Owad -- Sysop of Caesarville Online Client software at: <http://home.earthlink.net/~tomowad/>

Browsing old BYTEs - Signetics Instructor 50

by rcini＠email.msn.com

While browsing several old BYTE magazines, I came across an ad for the Signetics Instructor 50 SBC. Althoug the ad wasn't very good, it looks like it could be an SBC style S-100 Altair clone with a hex keypad, display, and data switches. Sort of an Altair-KIM hybrid (if one can imagine such a thing). Does anyone have any info on this beast?

Need an obituary for Don Tarbell

by dastar＠ncal.verio.com

Hello all. If you're not aware of this, Don Tarbell, of the famous Tarbell Cassette standard, died earlier this year. Someone posted about this on the list around the time he passed on. I'd like to display an "obituary" at the Vintage Computer Festival. I'll give a free pass to this (or a future) Vintage Computer Festival and a VCF t-shirt to anyone who wants to write up an obituary for Mr. Tarbell. Ideally, the write-up should include his contributions to the world of computing, including a good historical account of his cassette standard and other technical acheivements, as well as what companies he founded, etc. The requisite obituary information such as date of birth/death, hometown, etc. should also be included. I would need to have this by the 20th or so. Please contact me by private e-mail if you are interested. Thanks!

PSU question

by Philip.Belben＠powertech.co.uk

> I need to test a possibly bad PSU for an Apple II+. Can anyone > (tony?) tell me what I should use for a dummy load? I don't know what the Apple ][ or // used in the way of current, but Commodore PETs of that date used 2 to 4 amps, I think. (Early PETs, iirc, had 4 1A regulator chips on different bits of 5V rail). You want something to draw around 1/2 to 1 amp. 6V torch (flashlight) bulb - one of the nice krypton ones that runs of a big rectangular battery would be ideal. 12V 10W car lamp bulb would do, though it won't glow more than dull orange when working. 10 ohm resistor would work, but it probably needs to be a really big fat one - in a rectangular ceramic package or with built in alumin(i)um heatsink. Hope this gives you some ideas. Philip.

Osborne 01 computer smoked..

by roblwill＠usaor.net

It could be, as in the case of the adapter, a transformer. It could also be a capacitor. I don't know how they make sound, but when I used to turn off my old Leading Edge, there was a high-voltage Cap that would make a loud *Chirp!*, then whistle, and the whistle would die down in a few seconds. It did the same thing when it was turned on, but backwards. It would start out as a soft whistle, get louder, then disappear, as the sound probably went out of the range of human hearing. It sounded sort of like when a computer would power up in an old Sci-Fi movie. Is the computer otherwise working fine? if it is, and there's no smoke or crackling sounds (like heating of coils or other components) after it's been on for a while, I wouldn't worry. Is it a constant, high-pitched whistle? Not being familiar with the Osborne 01, dose it have a built-in CRT? It could be that that's whistling. Try booting it with the CRT and control board (the thing with the high voltage transformer with the wire going to the side of the CRT) TOTALLY disconnected, and see if it still whistles. If it doesn't, then you've found the problem. As for fixing a whistling CRT, I haven't figured it out, yet (If anybody knows how, could they please tell me?). The only problems that I've seen the whistling do is possibly make your ears hurt. My current solution: wear ear plugs when using my Tandy 1000. -- -Jason (roblwill(a)usaor.net) ICQ#-1730318 ---------- > From: Sam Ismail <dastar(a)ncal.verio.com> > To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> > Subject: Re: Osborne 01 computer smoked.. > Date: Friday, September 04, 1998 9:53 PM > > But what part is making such vibrations that it actually causes sound > waves to be emitted? > > Sam Alternate e-mail: dastar(a)siconic.com > ---------------------------------------------------------------------------- --- > Ever onward. > > September 26 & 27...Vintage Computer Festival 2.0 > See http://www.siconic.com/vcf for details! > [Last web site update: 08/25/98] >

I think ruling the CPU isn't exatly the way to describe this classes, since even a mainframe type computer can have singe chip processors, and a micro can consist of a whole chip graveyard. But your Note leads a trace: try the design goal as class. So, a mainframe is a general purpose computer specaly designed to transport, merge and modify data like a big steel plant modifies iron. Using only a small number of programms but serving the same task a _huge_ mass of users. Usualy these are just /370ish designs. A Mini is some kind of 'big' computer designed to serve a lot of people in an individual sense, giving every user (and sometimes even every single programm) the feeling of a complete independant computer. The OS is wasing a lot of resouces (not needed on mainframes) to ensure coexistence, fast programm change etc. The OS is mostly unix-like. A Workstation is 4M (you just missed the Megabucks :). A workstaton serves the needs of only one user. The OS is in most cases very graphic-able orientated. An average PC is just a workstation on a lower level, running several different application (maybe even at the same time) to serve every person as his own computer like a mini, but without sharing anything. The OS is almost complete graphic orientated. I think this sceme is sufficient for all GPC. If you miss the micro, its just because it represents no class of its own. The micro can be just a very small mini, or he is a PC(Workstation). Didn't the Wozniak once state that every micro before the A2 was just a small singe user mini ?

Equipment needs home: Portland, OR. area

by jimw＠agora.rdrop.com

Don't know if I'd actually classify this as a 'rescue', since probably the worst that would happen would be that the gear would end up buried in my warehouse, but... A couple of items that could use a new home. (just cause I don't have time to get to them at present) I won't attach a specific price to either but would like to see either a little $$ or something interesting in trade for them. (see the 'wish list' on my web pages for ideas) Both items are considered to be in 'as-is' condition. I've not had time to try to fire them up or do any check out since they came to me. Either would need to be picked up as they are too large (&/or) heavy to be practical to ship economically. 1) Cypher 9 track tape drive. 800/1600 bpi, 125IPS transport. Just the drive, no cabinet. 1) DEC PDP11/84. CPU only in 4ft. cabinet suitable for mounting drive in top bay. Drop me a note if interested. Note: my ISP is having problems with their dial up lines (darn US West anyway!) so my access to email is a bit sporadic at present... So don't panic if I don't get right back to you... -jim --- jimw(a)agora.rdrop.com The Computer Garage - http://www.rdrop.com/~jimw Computer Garage Fax - (503) 646-0174

I must comment that the real distinction is how they are marketed. Earlier, the size of the machine denoted its power and utility. Now, it's not possible to classify as easily.

old fax machine

by maxeskin＠hotmail.com

I just found an old fax machine in the trash. It has two connectors on the back: one is a DIN-6 labelled coupler. The other is DIN-8 marked NCU. The question is that I have neither coupler nor 'NCU', and does anyone have any idea how to wire this thing to a phone line? Is a coupler necessary, or can I wire the line right into the machine if I figure out the DIN-5 connector's pinout? This is a PERSONALFAX II , BTW. ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

The other is two low cabinets, the second holding a 1" Cipher Tape drive. Is there any interest in them or parts from them. Unless someone is interested they are a week or two from becoming parts & scrap. I am closing my warehouse shortly and need to get rid of them.

OS/VS-DOS/VSE-VM/370 Ass. lang manual

> I was going thru a bunch of old material and I ran across this IBM > manual that I had squirrelled away from a garbage find in the early 80s > that also included a bunch of Bytes. It's a 6th edition (Mar 79) and says it > applies to Release 4 of OS/VS1, Release 3 of OS/VS2 ,Release 2 of VM/370, > DOS/VSE, and all other releases > A descrptive heading says "This manual describes the OS/VS -DOS/VSE- > VM/370 assembler language. It's a 450 page XEROXed copy. > I know ziltch about non-micros and am wondering if this is of any value > (in the intellectual sense) ? /360, /370 ASSM is an brilliant example how simple, clear and beautiful a (CISC) processor can be. I know now other assembler so simple, so strikt and easy to implement (and I'm still an Assm programmer since 20 years). With exraordinary simple thinking one can easy develop all stages of an execution pipline for this opcode. Staight forward. Did I say develop ? There is noting to develop - reading the opcodes is like reading a step by step instruction to build the CPU. Ok, maybe I'm overemphasing, but I love this structure. I did almost any microprocessor (from 1802 to 9900 and Z80) in the past 20 years, and some of the bigger architectures, but none equals the /370. So, if you want to have fun, take the OP-Code table and solve the puzzle - or just keep the manual for 'real world' tasks, since this Assm is still valid for IBM (and compatible) Mainframes. I bet your taxes are calculated on one of 'em. Gruss H. P.S.: I did several interpreters for micros - first on the KIM :). P.P.S.: Shure there have been some realy genieous extensions to the /370 architecture (like maybe the stack engine in the SIEMENS X calss CPUs), beautiful and powerfull themself, but they are still don't met the elegance of the basic instruction set. P.P.P.S.: And of course there are several good Microprcessors - but again: not as elegant, simple and beautifull than the /370. -- Ich denke, also bin ich, also gut HRK

LCD woes

by ds_spenc＠alcor.concordia.ca

Immediately following my success with the Mac yesterday, I got to work on 'fixing' my portable '286 box with LCD display (which I think is _barely_ classic). The cable leading to the display had had three of its wires pulled out, and I figured that this was the reason for the very weak and grungy display. I managed to solder little bits of wire into the holes and solder the stray wires from the cable onto those, but then I realized that I couldn't plug the thing in anymore as the holes (from the underside) had filled with solder. :/ And I also realized that my solution was a bad one because the protruding wires would short against the metal frame that holds the LCD panel in place. So I used the connector from the C64 keyboard instead. Anyway, I got the cable rebuilt. I've tested it with the multimeter and all the wires make contact and go to the right places. But now I can't get any kind of display from the LCD panel. It doesn't light up at all. It looks like it's totally dead. I put a monochrome display adapter card in the machine, and it will boot up with that and display fine on a monochrome monitor. So the machine is _mostly_ OK. I'm not sure the power supply is OK, though. It squeals now. So basically, I've turned an ill-looking display into a dead display, and for some reason a healthy power supply is now sounding sick. Bleah! Anyway, the machine has a special card in it for driving the LCD panel. It is labeled "LCD & HGC CARD". What is "HGC"? It has an external 9-pin port on it and I tried plugging the monochrome display into it, but the picture was all distorted so I figured it was using a different frequency or something. The cursor comes out about an inch wide, and none of the craracters are recognizable, possibly just from overwritten numerous times in the same scanline. I don't know where I'll go from here. I'm just taking a breather before continuing. I wanted to be rebuilding the TS1016 RAM pack by now instead of still messing with this damn PC. <s> Oh, and BTW, I electrocuted myself last night when I touched some exposed wiring going to the LCD panel. It surprised me that there was that much juice going through there. My thumb and forefinger are still tender. But the display was still working at that point, and looking much sharper than it had been. But the machine wouldn't close up properly because the connector was too thick and that's why I went back in today, just to reverse the cable so that the big fat Commodore connector was on the inside instead of on the LCD panel end. (Which meant pulling the connector apart and rebuilding it the other way, just so it would fit in.) I haven't crossed any wires, I haven't plugged anything in backwards, and I haven't dropped anything into the machine, so I don't know what I've done wrong. <s> Doug Spence ds_spenc(a)alcor.concordia.ca http://alcor.concordia.ca/~ds_spenc/

PDP-11

by rexstout＠uswest.net

Just got a PDP-11/84 into the basement, and after the Series/1 experience I was ready... Go grab some 2x4 lumber if you ever need to get a rack system up or down stairs... Now that it's down, I need to get it running. When I plug it in and turn it on, it turns on the "DC on" light and the boot test display says "77". And what is the easiest way to hook up a terminal(probably use a WY-99GT or VT-220, maybe the WY-60)? It's a nice system with 4MB RAM and a 9-track Cipher tape drive(I noticed that the tape drive I have with my Series/1 appears to be a Cipher, or based on it as it needs a Cipher tool to prepare the tape for the autoload feature). Any ideas on how to hook the tape drive up? -------------------------------------------------------------- | http://members.tripod.com/~jrollins/index.html - Computers | | http://www.geocities.com/Area51/Lair/1681/ - Star Trek | | Orham(a)qth.net list admin KD7BCY | --------------------------------------------------------------

Mac 512K Working!

by ds_spenc＠alcor.concordia.ca

Hey, my Mac 512K is now working! In fact, I'm using it to type this message. Instead of going out hunting for more expensive connectors, I decided to use a dead C64 for parts. I pulled a male 9-pin D connector out of there, and while I was doing so, I also noticed that the C64 cartridge connector might be useful for repairing my TS1016 memory cartridge for my Sinclair. I don't think I'll go to hell for cannibalizing a C64. Besides, C64s are cheaper than the useful salvageable parts inside. Anyhow... I made a Macintosh to Amiga mouse adapter. I got the two X-direction wires switched around the first time, but it's all working now. I decided to use the lessons from the Laser 3000 and I poured hot glue onto the wires after they were all soldered into place, so that the thing is rigid, and then I wrapped it in electrical tape. :) So my Macintosh is presently using a two-button 'Pregnant' Amiga mouse. I should try the three-button optical mouse, but what would be the use of having TWO useless buttons? :) This is also giving me a chance to try out that old 1200bps Apple modem I pulled out of the Goodwill a couple of months back. Obviously it works pretty well! But I'm not used to this level of slowness anymore. I'm also not used to using Pico without arrow keys. Who's idea was it to use ^B, ^F, ^P, and ^N anyway? Couldn't they have at least arranged the keys in some sensible manner? It took me a couple of minutes to figure out how to configure the Option key to work as Control, too. I don't know what I'll do if I have to use ESC for anything. Did Apple think they were doing someone a favour with this keyboard? :/ Anyhow, I'm glad to see this thing works. Eventually I'll get around to fixing the real Macintosh mouse. Now... my display appears to be squished slightly on the left hand side. Can I fix that easily, without risk of electrocution? And what about that MacSnap SCSI board? Do I need special drivers for it or something? I can't get it to see my Zip drive.

The "official procedure" at the repair shop where I used to work involved a special little testing adapter (available from Apple, but probably only to authorized service centers) that plugged into the Mac's floppy port and split into four wires, one of which was ground. The other three were some combination of 5V and 12V leads (I think one 12V, one -5V, and one +5V, or something like that). You'd check all three and tweak each of them to within some tolerance, and according to the service manual, if you couldn't get all three within tolerance, then you were supposed to replace the board. -- MB

robots?

by maxeskin＠hotmail.com

I was volunteering for a short time at the Museum of Science, and they had a Terrapin LOGO turtle stashed away, and some descendants as well. The LOGO was controlled via an external box by serial cable. The descendants were programmable by IR connection. They stored them for lack of display space.I would have asked about the Amiga 500 deal with them too much. These people had no money, and they replaced an entire computer due to a PSU problem I had asked about before. Has anyone seen a turtle in action?

VIC-20 -- no sound

by Marion.Bates＠Dartmouth.EDU

--- Tony Duell wrote: According to the Tech manual, the output from the VIC20 is composite video and line level audio. There was an external RF modulator that plugged into that socket and connected via a switchbox to the aerial socket on a TV, but if you TV has composite video inputs, etc, then there's no need to use a modulator. --- end of quote --- I posted the original question. There didn't seem to be any need for a switchbox since the TV has these inputs already. Tony, your earlier post (thanks, BTW) describes the pinout for the correct video connector. Except that, um, I don't know the pin numbering scheme you're using. So, in this summary of continuity checks, I am counting pins from left to right, not knowing any better: Pin 1 -- nothing. Pin 2 -- tip of black RCA connector. Pin 3 -- sleeves of both red and black RCA's. Pin 4 -- tip of red RCA. Pin 5 -- nothing. So I guess that pin 3's corresponding with both RCA sleeves must have something to do with the video signal's being present even when I switch them around, right? But I'm not sure what to make of the rest of it. The answer is probably staring me right in the face from your previous post, but I'm pretty ignorant about electronics, so please bear with me. ;) Thanks again for the help. -- MB

Mac 512K Working!

by Marion.Bates＠Dartmouth.EDU

--- Doug Spence wrote: my display appears to be squished slightly on the left hand side. Can I fix that easily, without risk of electrocution? --- end of quote --- There are some adjustments you can do with plastic TV-tweaking tools (even demagnetized metal ones distort the display when they're near the board). The easy-to-reach ones are accessible from the solder-side of the analog board (there should be a white plastic sheet that tells you which controls are which). If those don't fix the problem, then you can cut away the blop of glue (more lessons from the L3K!) that's across the adjustment rings on the CRT yoke. Then you twist those rings (they have little "handles," sort of) and see what happens. However, the yoke IS dangerous, and of course you can't discharge it if you need to look at the screen, so watch out. Those rings are right near the Copper Wires o' Death. :/ -- MB

Tandy 3

by oajones＠bright.net

I was given an old Tandy 3 microcomputer. The button on the right side of the keyboard says "48K." Was this computer a newer version of the TRS-80 Model III? I am going to try and restore this computer. Right now it has a video problem. The screen lights up and has zig-zags on the screen. Also the contrast and brightness knobs are frozen and move just a little bit left or right. --Alan

I just thought it would be neat to have a computer that would run almost everything. I guess that's yet to be made. I have a Franklin 2000, but it's sort of screwed up in it's own way. It has two video outputs, that don't work simultaneously. One's 40 column, one's 80 column. To use an 80 column program, you have to turn off the computer, connect the 80 column to the monitor, and reboot. To use the 40 column, you need to turn it off, connect to the 40 column, and then reboot. It also uses Integer Basic, not ProDos, like most of the Apples. -- -Jason (roblwill(a)usaor.net) ICQ#-1730318 >

uVAX II Bugcheck help

by jpl15＠netcom.com

I have a couple of newbie questions re: the uVAX II that has come to live with me.. One is (and I have looked before asking) where might I find more technical data than the User's Manual seems to provide? Particularly sysgen info.... I need to a) find some device drivers and b) make them available to VMS.. specifically the TK50. There are no floppies installed. (nor in my other one.. boo!) Two is.. this old beast got quite cranky on me this morning.. it crashed loudly five or six time before stabilizing... I managed to capture the info once or twice, but I cannot verify that it was the same each time... most crashes came during boot after VMS signed on and somewhere right before/during the DATE/TIME prompt.. though it happened at other times too... FATAL CRASH Bugcheck... PGFIPLHI Pagefault IPL too high Crash CPU 00 Primary CPU 00 and a ton of other stuff... registers etc. which I will not reproduce unless asked. ;} It *seemed* to get better as it warmed up.. the machine is out in my shop and the ambient is about 68F and foggy... also it is not retaining the DATE/TIME info... is the uVAX as sensitive to it's battery state as some other machines? Has the RAM developed mange? Today I will move it in to the house where it can be given TLC... by the way, I have been asked re: the cabinet it's in.. it is in a 4' high roll-around rack, whose top hinges up to allow access to the Cipher 9trk tape drive. I don't have the cabinet model number. Thanks to All who have offered comments/suggestions so far! Cheers John

uVAX II alive

by jpl15＠netcom.com

Well, I fired up my recently-acquired uVAX II/RC up this afternoon, and whaddaya know... it boots! Thanks to the reams of information which I have dutifully stored away, I was able to get the system passwords reset, and I have VMS V5.4 signed on. Now I need that DECUS Hobbyist license. This machine originally booted into some kind of communications software.. but it went by too fast to read much more than TCP/IP and (I think) Excelan, or EXlan, or something.... This Machine has 1 RD53, 1 TK50(?) and a Cipher Data flatbed 9trk tape drive. (no floppy) The cartridge drive is not happy.. it will load the tape, but the red load light stays on, and VMS reports "device not found", and SHOW DEV shows it as unmounted. I would *really* like to discover how to mount/access the Cipher drive.. I have VMS 4.3 manuals, but I haven't found the right info yet on where to look for the device drivers and other procedures. The Cipher came installed with this machine, so I'm assuming at some point someone was using it... maybe. ;} ANYWAY: Thanks to Allison and Megan for various bits of wisdom that I have vicariously snagged and now put to good use. Now to wedge this thing into the rest of the gear in the Computing Centre (AKA Rapidly Shrinking Living Room). Sigh. Why did it have to be Minicomputers??? Why couldn't it have been Stamps?? Bottlecaps?? Toothpicks from Around the World????? Cheers John

THe AUX slot _is_ slot #3. just some different signals. For any 'regular' use you can only use the slot #3 connector or AUX connector. The Transwarp is just (like some other very special cards) desigend for uste in #3 while AUX is hosting the 'regular' card. In fact, any card, able to run in slot #0 (using no slot resources like RAM and (E)PROM space) will coexist in #3 with a card in AUX. The location was choosed to avoid that owners will plug in two cards using the slot resources into AUX and #3, since this (may) result in address conflicts. A far better solution than any message in a manual for the usual I-am-an-expert-I- -never-read-manuals user. Gruss H. -- Ich denke, also bin ich, also gut HRK

It's a 450 page XEROXed copy. I know ziltch about non-micros and am wondering if this is of any value (in the intellectual sense) ? ciao larry lwalker(a)interlog.com

Tandy 3

by roblwill＠usaor.net

It's not a newer version. My TRS-80 Model III also has 48K. It was the top-of-the-line Model III. When I first got mine, it had been sitting in a basement for 2 years, and the basement had been flooded when the septic tank backed up. when I cleaned it all out, and turned it on, I had the same problem with the screen. I gave it a good, solid whack on the back, and it's been working fine ever since (not too hard, though - you don't want to put a hole in the back). I think that the problem may have been that a couple of the chips got either corroded or slightly unseated, and smacking the back of it reseated them. That may not be your problem, though. -- -Jason (roblwill(a)usaor.net) ICQ#-1730318 ---------- > From: oajones <oajones(a)bright.net> > To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> > Subject: Tandy 3 > Date: Sunday, September 06, 1998 11:17 PM > > I was given an old Tandy 3 microcomputer.

Pixel 80

by cdrmool＠interlog.com

Does anyone have any doc's or info on a "Pixel 80"? A nice fellow in Guelph Ontario was kind enough to pass one on to me and I'd like to get it running. On quick perusal, it has a 5.25" drive on the front, and at the back a centronics output, 9- 9pin and 4- 25 pin D shell connectors. The date says 9/83. Its the size of the bar fridge I had in university and weighs a bloody ton. It was manufactured by "Instumentation Labratory Inc." Dominique who gave it to me says that he contacted them but they say they know nothing about it. There is a web site for IL but its no help. Colan

WTB: TRS-80 stuff.

by roblwill＠usaor.net

Hello everybody. I'm in the process of restoring a submerged TRS-80 Model III. It was sitting in my friend's basement when his septic tank backed up (yuk.), and it was sitting on the basement floor (double yuk.). However, his solution to fixing it was to drag it up the steps on sheet of plywood and let it sit in the rain for three weeks. Then he gave it to me because he was afraid to plug it in. I started by taking it apart, and hosing the whole thing down. Then I took all the boards out, and set them in front of heater/fan to dry (low power). I did the same to the disk drives, the keyboard, and the picture tube. After everything had dried for about a week, I put it all back together, and turned it on. The tube came on with a bunch of crazy characters on the screen. I took the main board out, propped it up behind the computer, tried it again, and the screen came up with the "Diskette ?" prompt. I put in a copy of TRS-DOS (unsubmerged), and hit reset. ERROR came up in 40-column letters. I shut it off, and pulled the drives. I stuck (well more like jammed- it was too wide) a 5.25" 360 half-height drive in it (it ended up at an angle and upside down to fit), and tried that. That time it worked, booting to the TRS-DOS screen, asking for a date. I typed "09/01/98". Nothing. I took a key off the keyboard to try to clean it, and they are the sealed-switch type. I had to unsolder each switch, take each one apart, clean it, put it back together, and solder it back to the board.

Booklovers: Danger!

by jpl15＠netcom.com

Maybe I shouldn't post this.... O wot'th'ell, here goes. I have discovered recently a very dangerous on-line book service, which, in my *very* humble opinion, just beats the bloody tar out of the 'major' ones.. (Amazon, Barnes, etc). Some of you Listmembers may already be aware of these folks.. if not, the URL is; www.abebooks.com I'm *definitely* in Big $$$ Trouble. I have a very large library, around 10K volumes, journals, periodicals, papers... collected over many years. A lot of it is old, wierd, rare, fringe-science, technology, engineering, computing, etc. Now I find ABE (American Book Exchange) and they've got titles I've been searching for for *ages*... including a book I read in 4th Grade and never heard of since... oh dear: most of the booksellers on ABE take credit cards... damn, damn, damn...! I've already found over $1K of stuff I must have.. NOW! Anyway, I hereby disclaim and hold myself inurred and harmless >from anyone who goes bankrupt because I turned them on to ABE. Just try searching with Van Nostrand or Wiley or Howard Sams entered in the 'Publisher' slot... or pdp-11 in the 'keywords' section.... I'm in **trouble** ! Cheers ;} John

Toshiba T4600

by rhblake＠bbtel.com

I am in need of a few things for a Toshiba T4600 VGA 486 laptop. The unit could probably use a new battery, this one holds for less than 5 mins after all night charging. I'm also interested in the users manual and possibly a docking bay, or at least the model number or part number of a suitable docking bay. Other reasonable items such as PCMCIA items that will work on it I may be interested in as well. ___________________________________________________ Russ Blakeman Rt. 1 Box 62E / Harned, KY USA 40144 Phone: (502) 756-1749 Data/Fax:(502) 756-6991 Email: rhblake(a)bbtel.com or rhblake(a)bigfoot.com Website: http://members.tripod.com/~RHBLAKE/ ICQ UIN #1714857 ___________________________________________________

Various things

by mark_k＠iname.com

Hi, A reply to a previous post and some other things... On Sat, 29 Aug 1998 Tony Duell wrote (Re: MAC ATTACK): >The normal sets in the UK are of 2 forms - either integral handle/blade >(just like a normal screwdriver) or a set of 1/4" hex insert bits and a >handle. In neither case will they fit into a classic Mac, alas. The >problem with the insert bit type is that the bit holder is too large to >fit into the Mac. CPC plc sell a "Macintosh Computer Case Screwdriver" for 1.19 pounds (+VAT). The order code is TL01544. They also sell a more or less identical one (Ideal brand) for over 5 pounds. Repair of switchmode PSU from SyDOS 44e external drive case ----------------------------------------------------------- I am trying to repair the PSU from an old SyQuest external drive case. The PSU is made by Skynet, model SNP-9533-2. It has +5V and +12V outputs, both rated at 2A. The fault is a short between the +5V and ground lines. This showed up as a twitching of the cooling fan, as the unit repeatedly shut down and started up again. Thanks to the sci.electronics.repair FAQ, I have found the faulty component. A schottky rectifier has gone short circuit. There are two identical rectifiers in parallel. The other one is okay. So, I need to find a replacement for the broken rectifier, which is marked as follows: 31DQ 04 3F According to the data sheet available from www.irf.com, the specs are: I Rectangular waveform 3.3A F(AV) V 40V RRM I @ tp=5us sine 470A FSM V @ 3Apk, T = 25C 0.55V F J T -40 to 125 C J Will it be okay to use any diode of higher rating than the original? Can anyone recommend a suitable replacement, or does someone have a spare 31DQ04 diode? Mac SCSI cable -------------- I have a Mac SCSI cable, which has 50 way Centronics type connectors on both ends. On one end there is a small "extension", the body of which is about 2cm deep. It has a male Centronics connector on one end, female on the other. The Apple logo is moulded into it, and the Apple part # is 590-0304-A. What is the purpose of this? When it is in the SCSI cable, I cannot boot (my non-Apple computer) without having the external MO drive turned on. Without this thing,it works fine. Maybe something to do with TERMPWR? Wangtek tape streamers ---------------------- I was lucky enough to find Wangtek 5525ES and 5150ES SCSI tape streamers the other week, along with a couple of Adaptec PC SCSI controller cards. One of these, assuming that they work okay, should finally allow me to read (if not make use of) my Amiga UNIX tape. Did the Wangtek streamers normally come with any PC driver software, or is this not necessary? Hitachi CD-ROMs --------------- I have some old external Hitachi CD-ROMs (model CDR-1503S, I think). These have 37-way D connectors on the back, and they came with a couple of 37-way D cables. It looks like you can daisy-chain two or three of these to one PC. The Hitachi web site was unhelpful. Does anyone know anything about these? Do they need a special interface card, or do they plug into the 5.25" drive port on the back of my PC (which is a 37-way D connector)? Does anyone have suitable drivers? It would be a shame to get rid of them, since they seem to work; at least, after powering on I can eject and insert discs. Sinclair Oxford 300 calculator ------------------------------ I bought one of these the other week. Is this the same Sinclair as produced the ZX80, ZX81 etc.? A quick description: Unit is powered by 9V PP3 type battery, has an 8 digit red flourescent display. A minimal range of scientific funtions; (arc)sin, cos, tan, ln, e^x, square root and reciprocal. There is a switch on the back to choose between degree and radian modes. Calculation of (for example) the sine of a number takes about two seconds. Unless I haven't figured out how to use it properly, the answers it gives are rather inaccurate; for example: square root of 2 = 1.4139192 e = 2.6108 (obtained by entering 1 and using e^x function) It may be faulty; repeatedly pressing the 0 button causes the number entered to be variously 22000000, 22220000 or 20000000. (Though I just tried this again, and it seems okay now.) -- Mark

Altos 586

by jeff.kaneko＠juno.com

I used to maintain one of these beasties in the late 1980's. It used Altos III terminals, which were just WYSE-50's with different color plasteek and slightly different firmware. It ran XENIX, which it seemed like it was of Edition 7 vintage. This particular one was a bit tempremental, and went down every few months or so due to hardware problems. It used a pair of Quantum 40MB FH hard disks. It think it could accomodate a 60 or an 80 as well, if I'm not mistaken (as I frequently am). Actually, it was a cool little machine. It was used for Cellular Telephone billing, and I learned how to use Unix on it. Shoot, I even remember the default root password after the Xenix was installed: 'sotla' :-) Jeff On Sat, 5 Sep 1998 11:09:04 -0500 "David Williams" <dlw(a)trailingedge.com> writes: >On 5 Sep 98, at 11:52, Allison J Parent wrote: > >> No, server is a newer concept.

My friend's 4-year old cousin put a penny in the top of the computer, and it fell on the disk drive PCB. When I took the computer apart, the penny was still there - fused to the top of the board, with a black ring around it. I'm not sure if they're Tandon or ALPS. The keyboard was made by ALPS, but I didn't look at the drives. I looked at Frank's TRS-80, and I tried to put my drive in it, but it was too long and wide. I noticed that his was a Model 4. It may have a different drive mount. From the picture, the mount looks like it's shiny metal. Mine's a dull, gray plastic. I'll try to get the model numbers from it. I think the stickers are still on there.

Osborne 01 computer

by handyman＠sprintmail.com

Hello everyone, I am needing schematics for an Osborne 01 computer, or some help in repairing it.. I just purchased it last week and was using it for about 30 minutes (It had not been used for some 13 years).. Worked perfectly and is in mint condition.. Then all of a sudden a crackle and smoke poured out.. It was still working but I quickly turned it off to save it from further damage.. I took it apart for a quick look expecting to find a burnt electrolyte capacitor in the power supply but did not see any damage.. I am afraid to power this unit up again for fear it will damage the mainboard.. Can anyone help me this is one of the finest old computer I have ever owned and I want to get it working again.. There must be someone that has schematics out there for it.. or maybe someone can help me dx it.. Thank You.. Phil Clayton

Followup to Toshiba 3100e

by roblwill＠usaor.net

The 286 chip in the T3100 series was smaller than the regular 286 chip (IIRC). The "fun" part about it was that it just dropped into the socked (loosely), and was held in place by the heatsink that snapped on top [one of Toshiba's *many* bad designs). If the computer would get bumped suddenly, or if the chip would move due to expansion and contraction of the chip from heat, it would need to reseated. There was also VERY little airflow in those machines. The power supply has a 1 1/2" fan, and the hard drive and floppy drive were directly in front of the internal air vents, basically blocking the already limited (because of fan size) airflow. The HD controller was also buried under the hot power supply. The controller would heat up, and the P/S would heat up, causing the HD controller to blow >from overheating, and making it seem like the heads in the HD were stuck (don't know if toshiba did this on purpose...). The HD's, if you can find one are around $150 for a 20 meg. I don't know the cost of the controllers, because I sold the thing for parts before I even thought about looking in to it. -- -Jason (roblwill(a)usaor.net) ICQ#-1730318 PS>> when the P/S starts blowing out air about as hot as a hair dryer set on "low" (about an hour and a half), you better turn it off an let it cool down for a bit (or just put it on ice). ---------- > From: Russ Blakeman <rhblake(a)bbtel.com> > To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> > Subject: Re: Followup to Toshiba 3100e > Date: Friday, September 04, 1998 5:52 PM > > Next best thing to thermal transfer compound.

FW: FREE PDP-11/73 with tape drive in Cheshire

Please contact him directly if interested. -=-=- <snip> -=-=- From: helbig(a)man.ac.uk (Phillip Helbig) Newsgroups: comp.sys.dec Subject: free VAX 11/73 with tape drive in Cheshire Date: 5 Sep 1998 12:40:26 GMT Organization: University of Manchester, NRAL Message-ID: <6srbfq$c0f$1(a)probity.mcc.ac.uk> Reply-To: p.helbig(a)jb.man.ac.uk NNTP-Posting-Host: multivac.jb.man.ac.uk Lines: 48 Path: blushng.jps.net!news.eli.net!news-out.internetmci.com!newsfeed.internetmci.com!194.72.7.126!btnet-peer!btnet!dispose.news.demon.net!demon!peer.news.zetnet.net!peer.news.bb.u-net.net!u-net!yama.mcc.ac.uk!man.ac.uk!HELBIG As mentioned before, I'm planning on doing inventory on some old VAX stuff I have and having a big give-away in a few weeks. By the way, I'm still looking for stuff myself, especially tape drives (8mm) and bigger SCSI disks---see http://multivac.jb.man.ac.uk:8000/helbig/vms/vax.txt . I especially want VAXstation 4000 or VAXstation 3100 boxes. When picking up my last lot, I decided to save an 11/73 from destruction, hoping I could give it a good home. I don't know much about it except that it has a good tape drive in it and two sizes of floppies (no, neither is 3?"---5" and 8"). I need to get rid of this quickly, as it is filling up my car and making it difficult to drive. It's a rack-mount. If you want it, then come and get it, but you better hurry 'cause it's going fast. Previous experience shows that there is a big demand for these old systems. It's first come, first served. I would prefer people who will take it in any case, as there's not much point in looking at it and I want to unload it directly from my car into your vehicle. I could arrange to obtain some manuals and perhaps even software distribution media, but not before you pick up the VAX (since I don't want to drive anywhere with it in my car); you could come back for them or I could probably tell you where to pick them up, perhaps on the way to picking up the VAX. Email is the best way to contact me, though the other methods below are OK as well. I barely managed to get it in the back of a VW Polo estate (the previous model; it wouldn't fit in a new Polo) with the back seat folded down. So you need a car at least as big, where the dimensions of the opening are as critical as the volume. If you're not too far away, I could drive it out myself (which might save some effort) but only if you promise me to take it in any case. As far as I know, it is in working order and there is at least the OS and some compilers installed on it. I don't know WHICH OS is on it. -- Phillip Helbig Email ......... p.helbig(a)jb.man.ac.uk Nuffield Radio Astronomy Laboratories Tel. .... +44 1477 571 321 (ext. 297) Jodrell Bank Fax ................ +44 1477 571 618 Macclesfield Telex ................ 36149 JODREL G UK-Cheshire SK11 9DL Web ... http://www.jb.man.ac.uk/~pjh/ My opinions are not necessarily those of NRAL or the University of Manchester.

I got e-mail from Adrienne Carter at Money Magazine (!) asking about the value "either financially or sentimentally" of the Commodore 4032 Pet. I pointed her at e-bay, but she doesn't seem to be just looking for a place to sell one. Unfortunately, I don't know much anything about those machines. So, if any of you out there want to chat about that machine, kindly write to her at this address after removing the letter "x"s from it: Adrixenne_Carter(a)tixmexinc.com . Thanks, Bill.

Apple II parts

by oajones＠bright.net

I have three Apple II motherboards, several floppy drives, and cards laying around. I would like to get one Apple II running. I don't have any experience with Apple II computers. Is there any old timers on the mailing list who can give me some help. I also will need the software for running the computer (the boot disk, ect.). --Alan

Osborne 01 computer smoked..

I have some old 6V 6W > bulbs . Would these work just as well ? Eh? 6V 6W bulb is exactly what Tony suggested. To be more specific, many power supplies have regulator circuits that expect some current to be flowing in the load. These PSUs will push out the wrong voltages, or shut down altogether, if you power them up with nothing on the output. Therefore, when testing power supplies, connect some sort of load device - it doesn't matter what as long as it draws roughly the right amount of current - to the output. Most computer PSUs regulate the voltage on the 5V rail and hope all the others will follow, so this is the best place to connect the load. Light bulbs make good dummy loads because (a) they light up when the current is flowing and (b) they are relatively small, cheap and easy to obtain compared with (say) resistors of similar value. 12V bulbs (e.g. car running lamp (0.3 A) or indicator lamp (1.75 A)) are good for loading 12V lines should you need it. 6V bulbs are good for loading 5V lines. 6V 6W flashlight bulb is good for small and medium PSUs; for larger power supplies I use a 6V 24W car headlamp bulb (yes, my truck has 6V electrics). 12V bulbs also work at 5V, but remeber they have a much lower resistance at 5V than they do at 12. DON'T use the "power good" line to connect the dummy load. This is a digital output - usually TTL level - which can only drive a few mA. DO connect the "voltage sense" line(s) to the load as well as +5V and ground. Philip.

Toshiba 3100e/40, locks up??

by foxvideo＠wincom.net

Just received a pair of 3100e/40's. One seems ok, the other will boot ok but after about four minutes the screen will freeze and the keyboard will become completely inoperative. Turning it off and on results in three or four bright vertical lines on the screen and no other activity. Turning it off for twenty minutes or so results in it booting up normally as above. Does anyone have any suggestions as to where to start? Regards Charlie Fox

Have you read _Once Upon a Time in ComputerLand_ by Jonathan Littman (I think)? If not, you should. At one point (before 1979) Bill Millard was pursuing an income-sheltering scheme that involved selling IMS to a south-of-the-border company that would liquidate it, then sell its intellectual property to yet another company located on the Isle of Jersey. Said third company would license the intellectual property back to IMSAI Manufacturing Corp. which would make and sell computers. IMSAI Manufacturing Corp. would pay a licensing fee; the third company would pay Millard royalties. I gathered this was never really completed, but Millard ended up going to some effort in an attempt to put things back the way they were, un-incorporating the old IMS Associates Inc. and IMSAI Manufacturing Corp. to release the names, and incorporating new ones of each. Also I thought that it was IMSAI Manufacturing Corp. that filed for bankruptcy and presumably sold its assets to Fischer-Freitas. IMS Associates was (I think) still the parent of both IMSAI Manufacturing Corp. and ComputerLand. Or maybe I don't understand it at all, IANAL. If you'd like to explain it to me I'd appreciate it. -Frank McConnell

Osborne 1 boot disk needed.

by scott＠isd.canberra.edu.au

Thanks to the advice on restoring my rained-on Osborne 1 (especially from Tony Duell - thanks Tony), it is now up and running, and asking for a boot disk, which of course I haven't got. Is there any way to create a boot disk from an image, and if so where can I find such an image? I'm pretty sure my Osborne has a double-density controller (it is the blue version, and the floppy drives appear to be plugged into a daughterboard). I addition to a PC with a 360K floppy drive, I have a copy of Sybex's 22disk and a copy of a much earlier program called ALIEN.COM, both of which can read and write CP/M disks in a variety of formats. (BTW, does anyone have a version of ALIEN.COM later than 1.0Fj?) I also have a Commodore 128D, plus external 1571 and 1581 drives, and I've found a CP/M program called Jugg'ler-128, which is supposed to allow reading and writing of around 140 different CP/M formats (including, it seems, Osborne 1 single-density). So given these resources, is it possible for me to create an Osborne 1 boot disk? I understand that I can get one (for a small fee) from the Dina-SIG CP/M System Disk Archives via Don Maslin, but this involves getting the disk shipped halfway around the world, not to mention the added complication of getting a few Australian dollars converted into (even fewer) US dollars. Also, is it possible to get images of the other disks that originally came with the Osborne 1 (Wordstar et al)? Are there any licensing issues with this? I would have thought that, since the programs came with the machine originally, owning the machine would imply having a license, but I'm sure things are more complicated than that.

On the other hand, this particular Marvin (not the one we're used to) is a) probably a CPA and thus perhaps not truly computer literate (why else would he be dumping perfectly good 486's?) and b) not subscribed to the list, so unless you BCC'ed him, he didn't get it.

If someone does a search on, say, "Altair", they're going to find several of the pages with list messages. They'll then send a message to the address listed (the list) asking how much their Altair is worth, or what have you. Probably without checking the date, btw, which is why we occasionally see messages like "I see you are searching for a rare commodore 64 power supply; I can sell you one for $199 plus shipping" when no one's been looking for a C PS for months. --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad roger(a)sinasohn.com that none but madmen know."

The physical address range for I/O page addresses is 17760000-17777776. On some machines this can be shortened to 760000-777776, and on some, even further to 160000-177776. (Though if you are referencing the I/O page from within a program, you must use a 16-bit value in the range 160000-177776, and the memory management must either be off, or setup such that the mapping registers for that range point to the actual I/O page). Have you examined memory beginning at 0 to see if there has been any code actually loaded from the disk? (Deposit something like zero or 177777 in a bunch of locations beginning at address 0, and after trying to boot, check those addresses... if they are different from what you entered, then that might indicate the disk has actually done something) BTW - what sort of DEC disk do your disks emulate?

Booting up and LSI 11/23

by gim＠hitec-uk.com

Tim, The drives are Diablo 30 drives, and the disks (there are several), are marked PDP-11 system disk, and PDP-11 Backup disk. The previous owner told me when I picked them up, that they should boot. Last night, I tried playing around with it again, and tried to access the disk status register (round about 17400(8) from memory, but I'm at work just now and it was late last night, so my terrible memory can't be sure...). It seemed to contain 000000 (from typing @17400/). :( Which doesn't, as far as I can tell from the assorted docs, look to promising for the state drive. An other potential problem is that I believe a clock pulse was generated by a CAMAC crate attatched to it. I've got the crate, but cannot attatch it at present because it needs a 110V supply, and I don't have my 110V transformer just now. My house is a 240V only zone at the moment, or at least as long as these machines stop tripping the surge detector!. I need to install a more forgiving fuse box. Thanks for your help.

PT SOL Arrives

by workapulo＠my-dejanews.com

Well, my new (old) PT SOL machine showed up (after nearly being lost by UPS) last night. Of all the classic machines I have gathered, this one was by far the best kept of the bunch. Bob Stek, the docs showed up (thank you) the same time. How nice :) Tony -----== Sent via Deja News, The Discussion Network ==----- http://www.dejanews.com/ Easy access to 50,000+ discussion forums

TI Compact Computer 40

by maxeskin＠hotmail.com

>So what is it? Any model number on the machine? >Francois The model is Compact Computer 40, abbreviated as CC40. It's a small 9 X 5.5 " unit, gray, with a full keyboard including numeric keypad, and a one-line 30-character display. It has 8k RAM and 2k ROM (I think) and BASIC and a monitor in ROM. A cartridge port, HEXBUS port for plugging in cool stuff which I don't have (like a tape drive), and AC adapter port. Runs on 4 AA batteries. Has lots of math functions as well. Comes with a manual, mostly about BASIC, and anothe r book called 'Learn BASIC: A guide to programming the TI CC40' It's made in 1983. There is an ad for it that runs '20 pages of notes, a thesis, algebraic formulas. Can you make a date at eight? Turn to your TI Compact Computer. By 7:14 your TI CC40(tm) has your notes filed, the changes made in your thesis, and all those formulas worked. The CC-40 goes where you go -- the classroom, library, anywhere. It's cordless, compact, sophisticated. It gives you much of the problem solving power of Apple or IBM personal computers. But it's a fraction of the size and price..." the ad goes on to say 6K RAM, 34K ROM, which doesn't agree with my manual. This thing runs at 2.5 Mhz,BTW. So, if anyone has any cartridges or accessories (that tape drive sure looks nice!) that they would be willing to sell/trade/give to me... ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

LCD update

by ds_spenc＠alcor.concordia.ca

All is OK! Even the power supply is quiet now. I think it may have been squealing only when the full load wasn't being drawn (I had both drives disconnected) and only for a few seconds after power-up. Anyway, the problem with the LCD panel was really nothing. The new connector simply needed to mate with longer pins to make proper contact. The pins at the back of the LCD panel were long enough, but the ones inside the machine were not. I ground down the connector a little bit and it works now. I also fully disassembled the casing to get at the variable resistor that controls the "contrast", because it was so dirty that I couldn't get a stable picture at all. I used an aerosol contact cleaner on it. I did find a loose paperclip during the disassembly. Hopefully it didn't do any damage while it was in there. The picture is now stable and clear. I used to get corrupted characters and strange lines on the display at seemingly random times, but I used the machine for at least six hours straight tonight and it never came back. The screen also used to be sensitive to movement and its position, and now it doesn't care if I grab it and flip it up while I'm using it. I'm guessing that several other wires were in the process of working loose. The screen is just naturally hard to read, but not nearly as hard as it was. The contrast has to be adjusted according to the user's viewpoint, and it's not always possible to clearly see the whole screen at once (especially up close). At some contrast settings, dark patches appear on the screen. Also, areas of the screen react to what is being displayed on other areas with a kind of ghosting, which can be a little distracting when the contents of the screen are busy. I'm guessing that this is normal for this technology. One really cool thing is that the characters appear to "float" on the screen. I think I can confirm a 1988 date for both construction and purchase. Most of the parts with identifiable date stamps that I looked at had date stamps of late '87 or the first few weeks of '88. Also, the contents of the hard drive which I never inspected very thoroughly (because of the screen) included personal and business (including many local businesses that I know) tax records from 1987 through to 1991. And yes, I did delete files of that nature as I found them. There were approximately 16MB worth of accounting files, and only software that would be useful in accounting, so clearly this was an accountant's machine. I'm a bit disturbed by the implications of finding such information at a garage sale. There is something strange about the display, BTW. It has externally-accessible dip switches. Four of them. And there's a note taped inside the panel that certain pieces of software require a certain switch setting. I attempted to install GeoWorks 1.00 and found that its installation program is one of the programs that needs that switch setting. :/ And no, I didn't get GeoWorks running, because I don't have a PC-compatible mouse. :/ (I picked up GeoWorks at the Goodwill this week.) Anyway, I'm still up because I've been watching the news all night. <shudder> Had it not been for that, I probably would have reported back with my success a lot sooner.

Well, reloading is a popular sport -- you take used cartridges, cast your own bullets (heat metal, pour into molds), and combine them with as much gunpowder as you like. Modifying the casing wouldn't be too hard, I imagine for anyone with any basic metalworking skills, nor would altering the bullet mold. As for computer cases, early models were probably handmade; it's not that hard. Take a run to your local Tap Plastics store. You can pick up all kinds/sizes of plastics that can then be made into just about anything. Also, model car/plane/boat shops probably have stuff to let you work with plastics. Even metal cases aren't that hard; I have a friend who built, as one of his first projects, an amazing set of cabinets/shelves for his Land Rover out of aluminum. Some simple tools are required, but nothing earth-shattering. I was talking to someone recently (Rax?) about building a custom wood-glass-and-brass case for a computer.

I just went through a huge ordeal similiar to this in trying to get Resnova's NovaServer (BBS server) put into the public domain. The following, of course, does not constitute legal advice. ;-) To quote Peter E. Converse: ---Start Quote--- When you say that ResNova "no longer exists in any way shape or form", that may mean several different things. It may mean that ResNova has gone through a Chapter 7 bankruptcy liquidation, that its corporate charter has been allowed to lapse, or merely that its operations have been abandoned. Each of these possibilities leads to several different outcomes. First, if ResNova is bankrupt, any intellectual property (like NovaServer) would pass temporarily through the hands of a bankruptcy trustee, receiver or debtor-in-possession. Then, this person probably would have attempted to sell this intellectual property to satisfy the debts of the company. If ResNova is still going through a bankruptcy, you could contact the trustee or receiver by checking federal Bankruptcy records. Second, if ResNova's corporate charter has been allowed to lapse (which is what I think you mean, if I had to bet), that corporation still owns the intellectual property in question, even though it no longer exists under the laws of the state of incorporation (subject to my comments about abandonment below). You might be able to arrange to purchase or license the IP by contacting the officers of the company. To find out who they are, you could contact the Secretary of State of the state in which Resnova was originally incorporated. This would probably be the State of its primary operations, or, alternatively, Delaware, NY or Calif. Any Secretary of State will tell you, over the phone, the name of the registered agent (prob an attorney or officer of the company) who could help you arrange a purchase or license. Third, if ResNova's shareholders, officers, directors and creditors have all disappeared, you might be able to treat this intellectual property as having been "abandoned." Unfortunately, if you do so, you may be subjecting yourself to legal liability for unlicensed use of the IP in the event that any of these folks turn up later. The burden in court would be placed on you to prove that you made a rigorous effort to find the owners and that they really had abandoned the asset. I would suggest making thorough investigations as described in the above two paragraphs before simply assuming that the asset has been abandoned. Of course, you should understand that this information is merely general and is not legal advice rendered as to specific facts. You should probably consult an attorney before taking any actions in this matter. Let me know if I can be of any further assistance. I represent a number of software developers, consultants, consumer product marketers and IT professionals. Good Luck. Peter E. Converse The Law Offices of Peter E.

>Also, who owns the rights to the Altair 8800 now? Percom? ICOM? Ed >Roberts? WHat happened after all the buyouts and bakruptcies? Which rights? The name? The design? The PC board layouts? The documentation? I would think the only things left to worry about are the name and any copyrights that might exist on the PC artwork. I doubt the actual design is protected at all - it's almost exactly what you'd get if you just took one of the Intel 8080A databooks and copied the CPU implementation. Why would anybody want to make an exact clone of the original design anyway? A couple months after the introduction of the Altair there were hundreds of garage-based businesses selling much better designed S-100 CPU's and peripherals! ----- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology Voice: 301-767-5917 7328 Bradley Blvd Fax: 301-767-5927 Bethesda, MD, USA 2081

TI-74 / PC-234 Problem

by mbg＠world.std.com

I also have a TI-74, with all of the rom cartridges, and the PC interface... I have not yet bought the printer for it... If you use AltaVista search for "TI-74", you should get the TI web site, which will point you to another site, which is where I actually purchased the stuff from. I also got some manuals on the TI-74... they have RAM cartridges, ROM cartridges, the printer, the TI->PC interface (and software) and some other stuff as well. They also have stuff for the TI-95 (ProCalc) Megan Gentry Former RT-11 Developer +--------------------------------+-------------------------------------+ | Megan Gentry, EMT/B, PP-ASEL | Internet (work): gentry!zk3.dec.com | | Unix Support Engineering Group | (home): mbg!world.std.com | | Compaq Computer Corporation | addresses need '@' in place of '!' | | 110 Spitbrook Rd.

For example, > Sheldon Leemon, author of "Mapping the C-64", tossed his old Atari > floppies that had held his manuscript. Just loosing _one_ media doesn't mean loosing copyright. If one wants to get rid of his rights, he has to proclam this in a prominent and usefull manner - like anouncing it in a state publication or any kind of aprobiate publication. Like puting an anouncement in a sourcefile. It's exactly the reverse way as claiming an title for a book or movie - If you want to avoide that someone else will use a title of a planned book, you have to anounce it in a aprobiate manner - i.e. in Germay you till put an add in the 'Boersenblatt des Deutschen Buchhandels' - a 'news'paper for publishing companies and book traders. For this case (reprinting a book), there are two and a half steps to perform: First try to get knowledge of the holder of rights. Basicly easy, since book rights are always originated by the author. Find the author, and ask if there are current licences. Apply for a licence. If he has no futher interest, he may offer it exclusive and unlimited for just a beer or two. Try to get a written statement. Geting licence doesn't include source material like disks or scripts - if they are lost, you still have to key in every letter again ... Second if you can't locate the author, or any other people possible owning actual licences or able to legitimate their rights, you are free to copy and redistribute the work. The hard term is 'unable to locate the owner' - judges (at least in Europe and especialy the US) put up very high bars to cross. You have to show that you did anything possible (Adds, writing to former publishers, companies, familie, friends, etc. searching directories). Now you can start to reproduce the book - BUT in your best interest you should take step twoandahalf: Opening a closed account (I don't know the exact US term - its an account where yo ujust put in money, but never take it back - possibly managed by a lawyer) for the author/owner of rights. Now 'just' pay the royalities into this account. If a beliveable owner of rights shows up, you just have to grant him access to this account. A possible 'new' royality agreement has to be made at this point. If the owner of rights disagrees with the summ (you have to open your books for double check sales and business regarding this licence) don't grant the access and wait for his court move. As long as your amount of saved royalities is reasonable any court decision inf favour or the owner wouldn't grant more, so be aware and don't put the royalities to low, becaus if the judge thinks so, the summs can be enormous - at leat within the strange US system. This method (step twoandahalf) can (and will) be used on any matter regarding intelectual properies - books, music ('legal' bootlegs use this to avoid geting dumped in the US) or patents (If company A won't give company B a licence, B could try it via twoandahalf - as long as they are able without support from A :) The trick is that you are NOT stealing the property - you are willing to pay, but some strange thing might hinder you. (This is even at wartime true, which leads to the very strange fact where Germany took a way more civilizated position than the US - Germany payed royalities even during the war for tecnologie used - including weapon tecnologie - while the US just declared any German patent or Trademark non existent. Some things can caus dizziness when thinking about) Ok, back to our book project: If you get the permission >from the author (like Sheldon Leemon) you're fine - don't forgett to ask if theres still a licence, maybe even a exclusive one for a publishing company, since in this case you still have to look for the (original) publisher. But regarding the KIM, with his chaotic past, a simple solution isn't available. Gruss H. Oh, and don't forgett: Even a non profit copying action is forbidden. so if a C= group, for example, make copies of the C64 ROM to distrimute within their group and friends FOR FREE, they are subject to pay royalieties. -- Ich denke, also bin ich, also gut HRK

Help on my MicroVAX 2000

I decided to run a number of different tapes to try to determine whether my TK50Z drive was defective or the tapes were not bootable. Below are the results of the tests.

TI Compact Computer 40

by maxeskin＠hotmail.com

I was just given one. It's a little Tand Model 100-like thing, it came with a user's guide and some kind of book for learning BASIC. Unfortunately, the manual is rather selective. Could someone tell me if I can use the serial port on the back for RS-232 communications, and what are the pin equivalents? If not, is there any kind of modification that could be made? Also, does anyone have any software cartridges for it they would be willing to send me? What is assembly like for this processor? Does anyone have any comments about it? ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

HELP! (Tektronix 4052)

by Philip.Belben＠powertech.co.uk

The last step before I cart my Tek to Santa Clara for the VCF: Insurance. Insurance companies don't like things without a replacement value. I have asked around how much to insure it for, and Dr Dooijes (curator of the Computer Museum in Amsterdam) has suggested $3000. Anyone else have any ideas: Are there any other 4052s around? What might be the market rate? Whom else can I ask? Also, anyone have any suggestions about how to pack it for the flight? Large box with lots of foam seems to be the best idea so far. Unless I can get hold of a Tek carrying case... Philip.

by jpl15＠netcom.com

Today I saved from the mythical Company Dumpster the following Stuff: DEC uVAX II/RC in 4' cab with Cipher Digital horiz. 9trk drive. Printronix P 300 Line Printer (from long-gone Prime Mainframe) Hewlett Packard : (2) 7914 disk drive units, one damaged in fall. An HP Systems cab with (1) 9144 and (2) 3000. (1) 2563A LIne Printer. (Very nice condition) Heads Up part: I do not particularly want the HP stuff, I took it to be nice to the warehouse foreman (to whom it's just junk he has to move around). SoCal area HP collectors.... any Interest??? Anyone? I have more than my share of non-DEC orpans now... heeellpppp.... WANTS: Unibus 9trk formatter card for Kennedy 9300, or preferably a TE16 and cards in SoCal or thereabouts. Need vacuum column door for abovementione Kennedy... or a whole 'nother drive... I'm not picky. MINC stuff. FSW Votrax (commercial Version) for PDP-11. An 11/750 w/magtape.... ? Cheers John

A 3000 in that sort of cabinet is probably a Series 37 or Micro 3000, a little departmental system good for about eight terminals.

TRS-80 Hard drives (was:Cable needed)

by roblwill＠usaor.net

I used to have a Model 1. I believe the logical answer for why Drive 0 was at the beginning of the cable was do that it was the closest to the computer, ant it would make it less confusing for novice computer users: Closest drive gets the boot disk. As for the drive with a resistor pack needing to be at the end of the cable, I disagree. I had a two-disk system, and both drives were identical. I know that, because when I first got the computer, I plugged the drives in, turned them on, turned on the expansion box, and turned on the computer, and they worked. I tried the drives the other way (switched them on the cable), and they still worked. I'm also sure that neither had the resistor pack, because when I got the computer, it was supposed to have 4 drives. There was, however, another Model 1 with an expansion box, but no drives. The person who was selling the computers took drives 3 and 4 off of the one that I got, and put them on the other one. My friend bought it, and the drives worked on it, too. -- -Jason (roblwill(a)usaor.net) ICQ#-1730318 ---------- > From: Tony Duell <ard(a)p850ug1.demon.co.uk> > To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> > Subject: Re: TRS-80 Hard drives (was:Cable needed) > Date: Tuesday, September 01, 1998 1:42 PM > > It would have been a lot simpler if the connectors had been fitted in the > opposite order so that drive 0 was at the end of the cable.

Back! I'm back... (now WinNT hit-and-run)

Its far less picky about its hardware (and a whole >lot more stable too, not to mention just a better OS). Yeah, then there's that really big market of Linux users who love to pay for software. I use Linux alot, but not for running Microsoft products or Windows code. All my firewalls and source code servers are Linux. The SGI version of my product easily recompiles and runs under Linux and X Window. We used it occasionally to use Checker and Electric Fence for debugging. I've got hundreds of unsold CDs of a Linux-based 3D product in the basement, left over from when my company was acquired. I'll gladly send a CD of it for free to anyone in the world who wants to send me a piece of old computer junk or software in trade. See my web page to see what I like. (See a description of Megahedron at http://www.threedee.com/mhedron/mhedron.htm>, and download a free, fully functional demo for Win95/NT x86 and AXP, Linux and SGI IRIX from <http://www.threedee.com/demos/demos.html>.) Frankly, Linux doesn't fit under the ten-year-rule. We'll need to wait until 2003 for that. Sure, it might run on old PCs, though. - John Jefferson Computer Museum <http://www.threedee.com/jcm>

TRS-80 Hard drives (was:Cable needed)

by roblwill＠usaor.net

The post about the Shugart HD's reminded me of something. I'm also looking for a hard drive and external disk boxes for a TRS-80 Model III. I'm not sure if the HD's needed to be special for the III (never had a HD for it), but I had model 1 disk drives on it, and they were working. So any model disk box should be O.K. ThAnX in advance, -- -Jason (roblwill(a)usaor.net) ICQ#-1730318

PC jr Stuff

by jeff.kaneko＠ifrsys.com

Guys: I just snarfed some PC-jr modules: 2 - 128k Ram expansion 1 - Parallel printer module 1 - Speech Module I cut open the speech and printer modules, and they seem to be in pretty good shape, although I don't know if any of this stuff actually works. If this is of any value to anyone, I'll offer it for trade for something interesting (I collect mostly Motorola related stuff), or some reasonable $$. PLease reply via private e-mail. Thanx, Jeff
