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. However, I just cleaned the <1>, the </>, and the <Enter> key- enough for me to enter the date. It worked. Now's where I need the help. Here's what I need: -5.25" full-height 360k disk drives (any type but Apple - doesn't need to be TRS-80). -External TRS-80 disk drives. -Cable to connect external drives to the computer. -TRS-80 Model III hard drive (can be a clone) -Internal cable connecting RS-232 adapter to the main board. -TRS-80 Model III software (can be on tape or disk) I'm also looking for anything for the CoCo Model I and II - ESPECIALLY disk drives and a printer. As always, ThAnX in advance, -- -Jason (roblwill(a)usaor.net) ICQ#-1730318

WTB: TRS-80 stuff.

A penny was once dropped into the computer by my friends 4 yr. old cousin. The penny landed on top of the top drive PCB, shorting some stuff and fusing the penny to a few components.

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
