Hi Folks! I've just picked up one these Miniterm portable terminals but it would appear that a couple of the EPROMs have gone bad. Anybody got one they could grab ROM images from? Cheers, Dave

moving stuff up the US west coast

by tshoppa＠wmata.com

> My first thought is to fly down, rent a > truck, fill it up, and drive back to Washington. My father thinks it > would be overall cheaper to rent the truck in in Washington, drive it > down, and drive it back. Sometimes U-Haul, Ryder, etc. have a shortage in one part of the country and a surplus in another part, in which case a one-way rental the "favored" way may be cheap, and the one-way rental the "other" way expensive. It will almost certainly be cheaper to do a one way move. Those big trucks don't get 40 miles to the gallon :-). Get a diesel if you possibly can. Plane ticket wise, since you mention central California, there used to be really super cheap plane tickets to Reno from Seattle and Vancouver (gambling trips) if that counts as "central California". Obviously I made the similar move in the 1990's in case you haven't figured it out :-)

DEC RX50 floppy question.

by roe＠liveblockauctions.com

I've got an RX50 that needs a cleanup. The heads themselves are no problem, but does anyone have a recommendation for cleaning the pads that hold the diskette against the head? They're some kind of felt or foam, fairly filthy, and leave a small round deposit on the top surface of the diskette... Thanks.

Howdy! I have this board and have no microvax, pdp or whatever to use it, seems to be a q-bus board. As you may know, these are impossible to find in Brazil (at least for a hobbist price). If you want it, pay shipping and it is yours, or send me a nice apple // or sinclair spectrum gift.

Setting the Scrolling Region on VT100's VT220's VT320's VT420's, VT510's etc.

by jhfinedp3k＠compsys.to

I have a simple request for anyone who is has a real DEC VT100 or compatible terminal (VT100, VT220, VT320, VT420, VT510) and especially VT100 software emulations, either as standalone software or as part of a PDP-11 emulator such as Ersatz-11. In respect of the latter, I have been using the Ersatz-11 PDP-11 emulator to support VT100 emulation with more than 24 lines for a few years. In particular, as part of the implementation, when the Range Escape Sequence is used to begin the Scrolling Region at a line less than 24 for the TOP and a line at the bottom of the screen for the BOTTOM, I use: <ESC>[16;255r to scroll between line 16 and the bottom of the screen. For real DEC VT100 terminals with the AVO option, there is ONLY one size for the number of lines, namely 24 lines. Since I can't ATTACH files to be sent to classiccmp, below are two files which can be used to erase the screen, set the scrolling region to line 16 at the top and line 99 or line 255, respectively, at the bottom of the screen. If the any VT100 (compatible) terminal or emulated VT100 terminal set for 24 lines is able to handle setting the scrolling region in this manner, each file with FIFTY lines should begin starting to display "Line 1 of File" of the file on line 12 of the "terminal" and "Line 2 of File" on line 16 of the "terminal" the and end up showing approximately six lines of the file at the bottom of the screen as the previous lines of the file scroll off the TOP of the scrolling region (at line 16 of the terminal) with just "Line 1 of File" remaining on line 12 of the "terminal". I would very much appreciate learning the results of sending both files to a DEC (or emulated) VT100 terminal. If they act the same was as Ersatz-11, the results will be identical with using 24 in place of 99 or 255. Jerome Fine P.S. When the file is transferred to the system, replace <ESC> with octal 33!!!!!!!!!!!!!!!!!!!! KED can be used under RT-11. The user eliminates each <ESC> and enters TWO <ESC> characters instead. Alternatively, if you can remember the first line correctly, you can enter the complete file in about 2 minutes by duplicating (cut and paste) the other 49 lines. ----------------------------------------------------------------------------------- <ESC>2JESC>[12;1HLine 1 of File<ESC>[0;99r<ESC>[16;1H Line 2 of File Line 3 of File Line 4 of File Line 5 of File Line 6 of File Line 7 of File Line 8 of File Line 9 of File Line 10 of File Line 11 of File Line 12 of File Line 13 of File Line 14 of File Line 15 of File Line 16 of File Line 17 of File Line 18 of File Line 19 of File Line 20 of File Line 21 of File Line 22 of File Line 13 of File Line 14 of File Line 15 of File Line 16 of File Line 17 of File Line 18 of File Line 19 of File Line 20 of File Line 21 of File Line 22 of File Line 23 of File Line 24 of File Line 25 of File Line 26 of File Line 27 of File Line 28 of File Line 29 of File Line 30 of File Line 31 of File Line 32 of File Line 33 of File Line 34 of File Line 35 of File Line 36 of File Line 37 of File Line 38 of File Line 39 of File Line 40 of File Line 41 of File Line 42 of File Line 43 of File Line 44 of File Line 45 of File Line 46 of File Line 47 of File Line 48 of File Line 49 of File Line 50 of File ----------------------------------------------------------------------------------- <ESC>2JESC>[12;1HLine 1 of File<ESC>[0;255r<ESC>[16;1H Line 2 of File Line 3 of File Line 4 of File Line 5 of File Line 6 of File Line 7 of File Line 8 of File Line 9 of File Line 10 of File Line 11 of File Line 12 of File Line 13 of File Line 14 of File Line 15 of File Line 16 of File Line 17 of File Line 18 of File Line 19 of File Line 20 of File Line 21 of File Line 22 of File Line 13 of File Line 14 of File Line 15 of File Line 16 of File Line 17 of File Line 18 of File Line 19 of File Line 20 of File Line 21 of File Line 22 of File Line 23 of File Line 24 of File Line 25 of File Line 26 of File Line 27 of File Line 28 of File Line 29 of File Line 30 of File Line 31 of File Line 32 of File Line 33 of File Line 34 of File Line 35 of File Line 36 of File Line 37 of File Line 38 of File Line 39 of File Line 40 of File Line 41 of File Line 42 of File Line 43 of File Line 44 of File Line 45 of File Line 46 of File Line 47 of File Line 48 of File Line 49 of File Line 50 of File -----------------------------------------------------------------------------------

Using an internal Superdrive or 800K macintosh floppy on IIgs

by alexandre.tabajara＠gmail.com

Stupid question, but here we go :o) In Brazil, as you may imagine, 3.5 drives for apple computers are pretty rare. But you can find with some effort internal macintosh drives from the tras...eh...performa computers that nobody wants. I got my IIgs (with no floppy drives) and made a simple pinout converter for using my old apple clone drives (http://www.tabajara-labs.blogspot.com.br/2013/06/e-quem-nao-tem-adaptador-d…). But reading the schematic of IIgs, I **BELIEVE** I can use the 800K or 1.44MB internal drives from macs into the 19 pin port of the IIgs. After all, is the same IWM the old macs use. I just have some questions which I wasn't able to answer yet: - How are 3.5 drives selected? I **believe** I must make an AND with ENABLEx and 3.5_ENABLE lines - Was it tested yet? I wasn't able to find anything concrete on the net - Superdrives doesn't have the speed select pin? - How is the disk ejected? I see no control for it on the drive pinout. I believe a combination of the pins or some kind of signal change is needed, but since I don't have an original apple drive, I'm not able to put the logic analyser and discover how it works :o( Thanks :) Alexandre (full of nasty ideas :D) --- Enviado do meu Motorola PT550 Meu site: http://www.tabalabs.com.br

PDP-11/34 verses a PDP-11/39

by lbickley＠bickleywest.com

When I saw Jack Rubin selling a PDP-11/34/39 manual on eBay, I had to buy it. I thought perhaps the "11/39" was just a misprint - but... The preliminary manual is titled "PDP-11/34/39 USER'S GUIDE" and is (c) 1975. Below the copyright is: "Written by PDP-11 Engineering". In perusing the manual, I quickly went to the section describing the two systems. Here's the opening paragraph in section 3.1: "PDP-11/34 AND PDP-11/39 SYSTEM DESCRIPTION" "The PDP-11/34 and PDP-11/39 Computer Systems consist of a set of modular building blocks combined to suit a customers needs. The PDP-11/34 System is designed for original equipment manufacturers [OEM's] while the PDP-11/39 system is designed for end users..." The manual then defines the "basic components" of each system. Both contain a KD11-E central processor, KY11-LA Operators Console, Unibus, M9302 Unibus Terminator and Core or MOS memory. The differences are: The 11/34 contains: M9301-YA Terminator/ROM The 11/39 contains: M9301-YB Terminator/Boot/Diagnostic DL11-W Serial Line Interface M7850 Parity Controller My guess is that DEC Marketing decided that only one system model made sense - and the original "11/34" configuration was scrapped and the "11/39" configuration became the 11/34 we know it... The manual also contains a number of hand written notes and corrections - and on first view looks to be substantially different than the "PDP-11/34 User's Guide" we 11/34 fans have come to appreciate.

WYSE Terminal Bummer

by john＠yoyodyne-propulsion.net

Damn! A few weeks after rescue, my wonderful WYSE WY-55 terminal has developed a fault. My son noticed it first. He said, "that thing is making a horrible screeching noise!" I couldn't hear it. At 44 I must be deaf to that frequency. Anyway, after a while, the frequency came down to where I could hear it screeching... and I began to notice what looked like "ripple" on the display... ...the sound is now loud enough you wouldn't want to use it... and it mostly doesn't work anyway. Most of the time when you turn it on, the screen stays blank and the keyboard lights stay on continuously. My experience with old Mac monitors says flyback. Could it be caps?

Sistron Donner Model 30 manual for the original model

by dmonnens＠gmail.com

Hello everyone, I am conducting research on early oscilloscopes and their usage and availability. I am looking for the manual to the original Sistron Donner Model 30 scope. I know there are manuals for later models of the scope, but I am looking for one from the original model. In addition, I was hoping there was any pricing and sales information on oscilloscopes from the 1958 to 1964 period, particularly the Sistron series. I'm trying to get a sense of the price range for oscilloscopes during this period (doesn't have to be just Sistron) and about how many might have been around. Thank you for any help! -Devin Monnens -- Devin Monnens www.deserthat.com The sleep of Reason produces monsters.

Your article on GenRad FutureData

by steamerandy＠hotmail.com

Hello. I found your description of GneRad FutureData. The ICE and development unites were separate. The development units contained a Z80 processor, not the target processor. We had a preparatory operating system. It had a command language similar to CPM. It also provided overlapping I/O. We supported Intel 8086 processors. Maybe a typo nut I do not remember it having a target of a 6802. We did have 6502 and 6800 ICE units. I do not remember having BASIC. We had a PASCAL compiler. Bill Author wrote the front end of the PASCAL compiler. I started with Future Data about the time GenRad bought them. I initially worked on the code generation for the 8086 processors. While there we developed code generation for the 68000, Z8000, 6800, 6502. I worked for them until they moved operations to the Bay area. Abdy

Quoting Jim Carpenter <jim at deitygraveyard.com>: > The data in xpcs00s.sys is almost certainly compressed. That's why you > can only find a couple strings in the whole thing. You'll have to > decompress it somehow first. Then you can disassemble it. Just a shot in the dark, but the cheapest copy protection is to flip some bits on the data bus. If you read a PROM on a programmer, all you see is garbage, until you figure out how the data bus was connected. Usually, nobody wasted the money to copy the ROM into an expensive SRAM to run it ...

Panasonic HHC emulator

by rouvin.remy＠orange.fr

Hi all, I am currently developing an emulator for the HHC (http://pockemul.free.fr). I have the main unit running quite correctly (thanks to Tony Duell schematics). The main goal is to emulate all extensions. I have made the RL-p1004A Rom dump with snapBASIC, but it is the only extension I own. I you have other extensions (plotter, RLP-1005 printer, video, serial ..) and snapBASIC, I'm interested in those ROM. I read all information about the HHC on this mailing list.

Next completely OT topic:

by derschjo＠gmail.com

Let's see... We've had the discussion about the Raspberry Pi, and how it doesn't have enough pins... We talked about the i386and how no modern UNIX supports it anymore and clearly this is a vast conspiracy by Microsoft... We've had the discussion about how awful / lazy / stupid modern developers and the kids on my lawn are... And the discussion about how great / awful functional programming is (oh, and Object Orientedprogramming). Outcome: C is the best, as usual... Oh, and the discussion about how teachers are useless... And a new one: discussion about eBooks vs. real paper books. Exciting and new! We also talked about how modern "PeeCee" (see, if you spell it funny that emphasizes your point) hardware is all terrible and falls apart if you look at it... Don't forget the discussion about "tablets" and how they will never catch on... We've done the discussion about USPS and how anything you send via it will be destroyed by monkeys in costumes or get lost... We've come full circle around to X and how useful it is/ how people don't need it... I *think* that based on prior history (and correct me if I'm wrong) that the next subject should be about how USB is not, infact, a "bus" and is stupid and awful and can't be interfaced to a ZX Spectrum and therefore is a failure oh God make it stop make it stop make it stop. - Josh

Xenix386 software?

by wlewisiii＠gmail.com

As another sideline in my vintage computing, I've been wanting to get a Xenix 2.3.4 system set up. No good reason, just because I think it would be fun. I used it briefly early in my career so I have a soft spot for it despite it's massive amounts of cruft and breakage. O_o I currently have the base OS & Developer Kit set up in emulation. My goal, unlikely though it is, is to get as complete a Xenix system as possible up and running on an old 386 or 486 class laptop. However, the various unbundled bits are rare as which ever proverb you care to use. The unbundled kits I'm still looking for are these: 386 Developer kit 2.3.1 (I have 2.3.0d) CGI 1.1.0 Text Processing 2.3.0 (nroff & friends) Manual Pages 2.3.0 VP/ix 1.2.0 vpix (run MS-DOS apps slowly.) TCP/IP Runtime 1.2.0 tcprt (it'd be fun to run Lynx!)

Huge supply of Osborne computers and parts in Orange, CA

by tosteve＠yahoo.com

I was contacted by Gary Berg about selling his late fathers Osborne computer systems and parts. His father was a local Osborne computer repair guy in Orange County, CA, but not employed by Osborne. During his time, he acquired hundreds of spare parts, and bought even more when Osborne went out of business. Because of this, he has lots of parts, some brand new, never used. This includes floppy drives, motherboards, keyboards, software, manuals, magazines, and even entire computers in the box, never opened.? Almost entirely Osborne 01 and 01a related. Some Executive parts. I can go back and look at stuff, but it is 30 miles away. Most will eventually go on eBay, unless you get there first. Yes, they will ship. Download pictures here (19 pictures, 4MB in total) http://oldcomputers.net/temp/osborne-collection.zip Contact Gary directly if interested in some or all -? garyvwguy at hotmail.com

What versions of Linux (or UNIX) are good on old 486 boxes?

by ethan.dicks＠gmail.com

Hi, All, Going through stuff on the shelf and I've run across a couple of 486-based fully-integrated LCD/touchscreen machines. One is a SCAN Corporation SCANtouch Model 3000, the other is a Planar Systems box. Similarities include limited memory (2x 72-pin SIMM sockets on the SCANtouch or 4x 30-pin SIMM sockets on the Planar, both with "double-sided SIMM" support, so 64MB or 32MB max respectively), one ISA socket (no PCI), onboard NE2000, serial, parallel, 2.5" PATA disk... these systems will run MS-DOS, of course, and Win95 (the touch screen on the SCANtouch is old enough that it apparently doesn't work with Win98 mouse drivers, according to forum posts I dug up). I really don't care about running DOS or Win95 on a touchscreen/LCD machine, and the practical alternative is some flavor of Linux or UNIX. What I'm having difficulty digging up is when the break from low-mem/pre-Pentium systems happened and what distros are on which side of the divide. RedHat 7/8/9 require a Pentium and 64MB minimum >from what I can research/remember. The last time I ran Linux on a 486, it was Yggdrasil (and before that, some early form of Slackware on a 386). So... anyone have a "go-to" Linux distro for sticking on a 486? I know RedHat 5.2 will work - that's what's on my PS/2-E (w/486SLC and 12MB of free mem I was recently discussing). Any other choices? At one time, when a Dell P-133 Latitude laptop was my main machine, I ran Solaris 7 on it (because it was a better choice than Linux at the time) even though it still had some issues (and workarounds) with the NeoMagic video chipset and the 3Com 3C589 PCMCIA NIC. I suspect this is likely to have similar "challenges". I've dug up full specs on the Scantouch 3000 innards - PCM-4890 integrated CPU board, NE2000 (Realtek RTL8019) Ethernet, C&T 65545 video chipset w/800x600 max LCD resolution, Sharp LM10V33 VGA (640x480) 10.4" color LCD, VIA VT82C496G chipset, , PC104 sockets... so I have little concern about getting *something* working with it. Getting 10-year-old RedHat working on a Pentium-class machine isn't a real challenge, but it's been long enough since I've really fiddled with 486s that specific memories of system configuration are getting a bit fuzzy. At one time, over 15 years ago, it was a daily thing knowing the ins and outs of what the 486 could and couldn't do, before CPUs and memory and clock speeds took off like a rocket, and when 4MB was ordinary, but more than 16MB was uncomfortably expensive for hobby gear. Helpful suggestions wanted. Thanks, -ethan

Esperanto as natural language [was RE: Learning simplified versions]

by RichA＠vulcan.com

From: Fred Cisin Sent: Thursday, May 23, 2013 1:19 PM > Should we define Esperanto as a "living human language"? That is a question that has arisen in the context of creole studies and the study of linguistic universals in linguistics. Esperanto as defined by Zamenhof violates several apparent universals of human language, and speakers have smoothed out some of those rough edges. In addition, there are reports of native speakers of Esperanto, defined as children for whom it is the first language, learned in environments in which only Esperanto was spoken. These reports have been questioned, as one might imagine, but I personally have not followed up on them as they fall outside my personal interests. So: If there are children who speak it natively, then the answer to Fred's question is certainly "yes". Given the very large community for whom it is a useful second language, with literature as well, then the answer is "yes, probably". If it were restricted (as it is not) to a minimal vocabulary with no potential for growth, then the answer would be "certainly not". I'm of the "yes, probably" camp most of the time.

[[Citation needed]] More to the point, some kind of evidence that this is a significant factor.

[1] You do realise that you are over-trimming (*again*) and replying to 2 different people in a single message here, don't you? In this one, you're answering me, via an answer to someone else who quoted my text. [2] You're trying to do something which FB is specifically trying to block -- IOW you're not using a browser, you're trying to scrape images directly via a script -- and you're complaining that FB's efforts to prevent /exactly the sort of thing that you're doing/ are successful?

I must say, though, that most of the old-time Linux users that I know -- the determined hardcore who were using it in the 1990s, who've been on it for a decade or more -- have almost *all* switched to Mac OS X now. > But Android solves a different problem: a mobile phone/tablet OS, not > a workstation OS.

(I've thought of cool things to do CAD drawings for, only to find them already finished years prior, and I'd forgotten doing them.) Your posting reminds me that I was waiting for the BM8L drawings at one point, so I have no doubt you are correct.

Xenix386 software?

by wlewisiii＠gmail.com

Thanks for the information all. I didn't expect anyone to have the software but you never know unless you ask :) A few things - the OS & Dev Kit can be found. The torrents & such suggested up thread are only various versions of the OS. They work in QEMU with some fd fiddling. I can't get it to run right in Virtual Box :( which I'd far prefer to use. There are lots of blog posts and Youtube videos on how to get the OS running in emulation. My next step in the emulated OS is to get the y2k patches installed as well as the various ported free software onto the emulated drive for installation. Lacking a TCP/IP stack probably means I'll have to somehow do it by serial or by (somehow) creating diskette images with various software on them. Perhaps with real floppy then dd ing it and mounting the resulting image? The other unbundled kits are what is missing. I'd really like the text processing, streams & TCP/IP kits but they & their licenses seem to have vanished into the ether. The only copies of Word and FoxPro that I've found I can not get to work correctly in Xenix386. They may or may not work correctly in a later (Unix, Open Desktop or Open Server) version. One other "just in case" - anyone got a copy of SCO Open Desktop 1.1? That was about the same time as Xenix386, had X11 & TCP/IP built in and Ingres DB bundled. I'll keep plugging away at it in case I get lucky :) William -- Live like you will never die, love like you've never been hurt, dance like no-one is watching. Alex White

These non-desktop, non-mobile phone systems have completely different requirements, and for many of them the facilities that X-Windows provides are extremely useful, if not essential. This isn't the first time you produce strawman arguments like this one. I don't know why you keep doing it, surely it must be obvious from reading the list that most people here are not concerned with what the average consumer needs or wants, or with what is a commercial success in the consumer arena. What becomes a "commercial success" according to your definition (sold to millions of average consumers) depends very little on technical merit and very much on marketing, trends, perceived coolness, what celebrities do, and so on. There is a huge area of applications outside of that world where technical merit is actually important. /Jonas

Only one problem there, most (if not all) EIA-232 adapters for USB won't go below 300 Baud. It is a problem when trying to get the old ASR33 to type things out! Of course you need to also add two stop bits, but that is pretty easy (as he notes the only place two stop bits were used was for the 33/35 teletypes).

Yes, but you are equating the "mainstream of the computer industry" with desktop machines, phones and Web servers, more or less. What I mean is that those parts are a large portion of the computer industry, but not necessarily the "mainstream". For very many applications of computers, they are completely irrelevant. It is like saying that Hollywood is the mainstream of the movie industry. True if you restrict the world to the US and Europe, but if you look at the world as a whole, it is only a part of the movie industry. /Jonas

A quick question re mixing old & new monitor connections

by lproven＠gmail.com

Can anyone think of a cheap, simple way to connect a DVI-only PC to an old Apple 17" CRT with only an Apple DA-15 connector? I have just been given a neat small-form-factor Dell P4 3GHz PC. I would like to give it to my mother. Her current computer is an old beige G3 Mac with a 17" Apple display. I will probably have to fly to visit her, and I can't afford to buy her a new screen. So, if I could connect the PC to her old monitor, that would be ideal... -- Liam Proven ? Profile: http://lproven.livejournal.com/profile Email: lproven at cix.co.uk ?

Five PDP-11 Questions

by captainkirk359＠gmail.com

Hello list: Going back on-topic from the recent wave of off-topic posts (that is, assuming people consider the PDP-11 both classic and on-topic), I have five PDP-11 questions which I wish to post to the list. 1. Is the bootstrap for the MRV11-D (the MXV11-BF boot ROMs apparently) "conversational" or "automatic." Conversational being defined as similar to the BDV11's bootstrap, automatic being, you hit the boot toggle and the system automatically brings up a <device>. 2. Is there a 22-bit QBUS bus terminator board? (I.e. only a 22-bit terminator, no bootstrap/ROM, no DMA refresh, et cetera.) If there is what is it's name? 3. Somewhat tying into the above, but; is there a 22-bit version of the BDV11 bootstrap ROM/bus terminator board? Because personally I'd rather deal with a single quad-wide board I've dealt with before, then deal with a pair of boards I've never even *SEEN* before. 4. This is more an opinion question but... Would trading a KDJ11-BF (yes, -BF; it has an FPU) for a KDJ11-AC (or -AB with FPU; FPU required because it took me long enough to get a J-11 with an FPJ11-AA, I'm going to run my '11/73 with an FPU if it kills me), a MRV11-D/terminator or 22-bit BDV11, and a DLV11-J be a good trade? (More on this question later...) 5. What size of wire, and wirewrap tool is the one most best usable when dealing with the jumpers (and possibly backplane) of a DEC system? (Specifically, in this case, wirewrap jumpers on various PDP-11 option boards). In terms of my question number four; I ask of that trade because I have a KDJ11-BF and an H9275-A backplane (that's the Q22/Q22 serpentine 9x4 one), as I'm in the process of replacing my PDP-11 system. And -- natrually -- the -BF (being PMI) won't play nice in the H9275-A. So I would like a trade for a functionally similar set of devices in this case a KDJ11-AC (or -AB with FPU; read my FPU statement), some form of bootstrap, and a SLU (the bus terminator would be nice as I plan on filling up said H9275-A). Thank you, any who respond, Christian G.

Kaypro successes

by brain＠jbrain.com

K4/84 has 2 new drives. Thanks Dave. ON that success, I pulled the K10, and temp attached a TEAC FD55. No joy on the boot disk I created (it goes to top left screen with cursor, then resets), but Gene B had sent me a complete set (I assume HDD restore set) of K10 disks (again, thanks Gene), and Disk #1 booted the machine. The same disk does not work in the internal FDD, even though the internal FDD does the same reset cycle when used with some boot disks. the existing HDD must partially work. Anyway, I wonder if someone else has a K10 and could help with HDD diagnosis. If I leave out the boot disk, the HDD ready light comes on after a bit, but then the K10 Disk #1 won't boot the system. If I boot the floppy, the drive ready light never comes on. And, things like checkbad.com won't find the HDD And, in either case, I can't hear the ST225 spin up. Should it? I am perfectly content if the diagnosis is a toasted HDD (expect it, I do). But, if so, where should I go looking for a spare? I see this on eBay: http://www.ebay.com/itm/SEAGATE-ST-225-21MB-MFM-5-25-HH-Hard-Drive-with-ORI… And I understand it's a gamble, but I assume my options are limited.

El Reg : Nuke plants to keep PDP-11 UNTIL 2050!

by seefriek＠gmail.com

My brothers company is a specialty shop that does IT related services (mostly custom development work) for small to mid-sized manufacturing companies (bro is an industrial engineer by training...he speaks the language). He periodically pings me because a client has something outside of his core competency and he want's me to take a look and see if someone in my network can help out. Sometimes it's a PDP-8 (or several) running an industrial loom, or a DG Nova controlling a CNC machine the size of a bus, or some ancient IBM thing cranking out invoices/schedules/statistics in the back room. Or an industrial grade PC (8088 vintage) running a DOS app and custom A/D-D/A hardware where all the menus and doco were in Italian controlling a fabric dyeing machine about the size and shape of a Soyuz (I got the call on this one because I can passably read Italian, not because of a technical value add). There's a cadre of folks I can count on to help out and never fail to miracle the odd replacement part or bit of code to keep things going (for a price, of course). There will absolutely be shops running things much older than a PDP-11 in 2050.

I have a vague recollection that early time sharing systems, in particular UNIX, enforced I/O fairness by fragmenting files and thereby freeing the I/O between fragments. However I don't recall much and this might be an artifact of aging :-) If so, I am curious as to how this was implemented - interleaving sectors or some more complex physical fragmentation or ?? Anyone point me to any references? Tom PS: as in infrequent poster I am happy to make a small change to the statistics

Looking for: Sperry/Beckman SP-333 (gas discharge display)

by derschjo＠gmail.com

I'm working through repairing a Tektronix 31 calculator for my dad (late father's day gift...). It seems to mostly be working now but all of the display panels except for two are dead (as I understand is pretty typical). The display consists of two SP-333s and four SP-332s. I've found a source for the SP-332s (2digit 7-segment displays) but can't find much for the SP-333s (3digit 7-segment display). Here's the specs: http://www.tube-tester.com/sites/nixie/data/SP-333/sp-333.htm Found a couple of "request a quote!" type listings on the 'net but that's about it. I need two of these beasts to get things visible again... Thanks in advance, Josh

Antiques roadshow

by jws＠jwsss.com

I've gotten tickets to an upcoming one of these, and besides a couple of items which fit their profile, am thinking of taking at least a small board or so to see what that does with their appraisers. anyone have any experience with them. This is the US mob. I'd never consider doing it with the UK ones. they want stuff from the 19th century or before, or WW2, etc. I am taking a sextant and a platinum broach. I have what I think is a Dec trainer board I'm going to take. i doubt taking any minis would be more interesting than the dec trainer. If they don't know that is a bit rare, then anything else they would say about other items would probably be useless. I'd like to see more scientific and computer, calculators, etc., on the show instead of the crap they sometimes have. Seems like everyone has a Tiffany lamp, or a bit of scrimshaw to show (fake and plastic, respectively). I was advised in an email that oddball stuff had shorter waits. Only guarantee is to get into the filming room where the appraisers are, and get stuff appraised. Will report back if there is anything useful that happens. Jim

pen plotters?

I was Googling for information on the control codes for an old CalComp 1042 PCI roll plotter we have tucked away and found your 2007 message about possessing a copy of the technical manual with, I think, the command set for plotters like this.

RS232 signal chracteristics

by ard＠p850ug1.demon.co.uk

Chuck (I think) mentioned that he had never seen a proper specification of the RS232 (or whatever) signals. I think CCITT standard V.28 is much the same thing, and it can be found at : http://www.etsi.org/deliver/etsi_tbr/001_099/002/01_20_63/tbr_002e01c.pdf It certainly seems to have reasonable descriptions of the signal electrical characteristics. -tony

Straight 8 front panel

by blstuart＠bellsouth.net

As far as I can remember, every straight 8 I've seen in the wild and almost every picture I've seen has the dark plexiglass panel with the paddle switches similar to those on the 11/20. However, I have a copy of the user's manual dated 12/64, and the picture of the machine on Page viii has what appears to be a simple brushed aluminum panel with little light bulb covers sticking through it and the switch register switches are all ordinary mini toggle switches. So my question is were there any ever shipped with that style of front panel, or was that picture of a prototype that was revised before any shipped? BLS

Software Sounds (on 45)

by derschjo＠gmail.com

I snagged this record off eBay because I knew it had to at least be interesting... thought you all might get a kick out of it: http://yahozna.dyndns.org/scratch/softwaresounds/ (mp3 and raw wav available) It's entitled:'Software Sounds - "Music for the Computer Professional"' and is apparently the creation of a man named Laz Bouros (who apparently never made it as a rock star but is today an Executive Consultant, if the Internet is leading me true). There's no date anywhere on it, but it has to be from the early-mid 80s. It came with a small pamphlet describing the both the record and the record label, which I will transcribe for you: ------ The Company: Software Sounds is an independent Canadian record company dedicated to developing a new market in the record industry through the use of an innovative musical product. The Market: The millions of computer professionals who operate, program, design, and manage computer systems throughout Canada and the U.S. provide a dynamic yet untapped market for the music industry. The Products: "Computer Songs", in a soft rock format, with lyrics that capture the human struggle as well as the lighter side of the computer world, are the new musical products. The Writer: Laz Bouros, a computer consultant and composer, has spent many years working in the computer environment and has written many songs on a variety of themes. ------- Alas, music for "the millions of computer professionals" never caught on, perhaps it couldn't compete with Devo andKraftwerk? - Josh

On the other hand, I regard protective ground as something that seemed like a good idea at the time but what protection it would provide and how did not seem to be adequately thought out until much later versions of the standard, if at all. When making up an serial cable, I usually leave it out, not out of laziness but because I think I'm probably as well or better off without it. (at least that's my excuse and I'm sticking to it!)

Well, if you check out some of the other classic computer lists I think you'll find that the above environment is still very much alive and you'll find some of those 'silent' folks over there instead, as I'm sure some folks on here who also belong to those other lists can confirm; the day rarely goes by when Chuck doesn't help someone with advice, an uploaded file or two, even on occasion a small custom program over on Erik's Vintage Computer List, and there are many, many other people helping each other out, trading parts, building new add-ons, sharing experiences etc., there and on other lists like the Cromemco list, Club100 (R-S), CBM-Hackers, etc. etc. Sure there are more 'collectors' these days who are interested in $$s, but I think that's really almost a separate issue altogether and I don't see much of that on CCtalk anyway. I'd say that it's not so much the hobby that's changed, but the mood and character of this list, or perhaps it's only remained the same while others (especially the VCF) have sprung up where newcomers are warmly welcomed, birthday greetings are exchanged, 'PeeCees' and Microsoft products and users are not disparaged or insulted, nobody quibbles over top vs. bottom-posting, name-calling is discouraged, and for the most part people talk about classic computer issues. As I said, you'll find some of the folks who are now 'silent' here hanging out over there instead, not to mention those folks who are on several lists in addition to this one and generally much more active on the other lists; even Gene tends to be much nicer on the VCF ;-)... I have talked to several people who thought it would be useful to join CCtalk, but after reading through a few days' worth of traffic decided it would be a waste of time... That's really my point when I climb up on my soapbox...

Alternative 4P4C (RJ9) connector sources

by brain＠jbrain.com

This is evidently the connector on the Kaypro keyboard: http://www.digikey.com/product-detail/en/TM1R-616P44-35S-150M/H11390-ND/113… Well, close to it, anyway. The original seems to be a Berg 616p And yes, it's erroneous to call it an RJ9, but it's easier to find in the store if you go that route. Before I go plunk down $7.10/connector for 5 connectors (mouser has a bit cheaper price, but their pic is wrong), anyone have a source that's not so steep ($36.00)?

Come back soon. I wouldn't worry; I don't think he'll be gone long ;-) For the record, despite his intolerance I like Dave (and have expressed that privately), appreciate the contributions he makes to the list and the hobby, and even enjoy following many of the OT threads on this list and the insight they give into different peoples' attitudes and perceptions in this particular niche of social networking (at least until they become utterly boring and repetitive and/or downright nasty). It's unfortunate that my coming to the defence of people like myself who apparently "suck" and posting those *amusing* statistics and congratulating him on being the clear winner in the post sweepstakes (emphasis on 'amusing') was seen by him and others as an "attack" and just provoked insults and counterattacks, with Dave taking his ball and sulking in the corner. But if it results in fewer banal, confrontational and same-old-same-old posts on the list and less stress for Dave and more time to spend on his more pressing matters, then that's a good result all around. Meanwhile, let's all lighten up.

The jerk factor on this list has become so high of late, and the clue factor so low, that I will take a respite for a bit. It seems I can no longer resist the attempts by jerks to get a rise out of me. Actually, I should say the "rise-able" people here in general, as I don't feel singled out, except by Mike Stein this morning...I'm just a bit more "rise-able" than I should be. But either way, for that I apologize. I'll be back when my stress level drops a bit, or when the jerks leave, and when there's something to talk about. -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Being called a moron and a jerk and being told that I suck because I don't see anything necessarily wrong with scrapping a system for parts could certainly be considered rude and offensive, but that really just reflects on the name-callers' character and maturity. There's no question that pretty well everyone on this list has things to contribute, including and sometimes especially Dave and the above-mentioned high posters; what I (and, I think, Josh) are suggesting is that the noise level gets pretty high sometimes and that perhaps the relatively few people creating most of the noise might take a moment to think whether that opinion, argument, whatever, is really worth the bandwidth and time to post, not to mention the replies that it will provoke. But predictably, it's just like asking the neighbours to please keep the noise down a bit; the usual reply is a hostile "go f$%k yourself" and the noise gets cranked up even more. I still think that it's a shame when the noise drives valuable people to other, friendlier, lists with higher S/N ratios; they don't seem to be missed by anyone else here and I'm on those lists as well, so no problem I guess. IMO, other than for HP and DEC issues CCtalk is becoming less and less relevant to many members of the community, but perhaps that's as it should be... So, no, I'm not offended; I'm also subscribed to CCtech so I can choose to just read the 'edited' version, or even unsubscribe altogether if I do get too annoyed or even "offended."

Well, yes I did (it was a Saturday), but it didn't take very long, even on a 486 running DOS; I was curious, it was a fun quickie program to write and I thought maybe someone else on the list would be amused as I was; unfortunately, and perhaps predictably, Dave was not amused by being the #1 poster and saw it as an "attack" instead. Year to date is even more impressive: 513 posts with the third place entry a paltry 285; surprisingly, Fred is #2 with 335, but his are usually short and funny.

You're only going to post when there's actually something to talk about ??? Who could ask for more! ;-) Definitely, get that stress level down; it's bad for your health! Best wishes, m

Imlac board photos

by derschjo＠gmail.com

*also* meant toshare these. Scanned in all of the boards in my Imlac PDS-1D for reference purposes, since there are very few of these out there (and schematics, but no PCB layouts.) https://plus.google.com/u/0/photos/117997069161125071032/albums/58762337385… I have high-res(600 dpi) scans if anyone wants them. Sure, it's overkill but why not... - Josh

Amusing statistic

If you do, > as your wording seems to imply, I have to wonder, why are you here? For the occasional post that is actually related to 'Classic Computers', as opposed to the endless kvetching about (other) people, 'PeeCees', M$ etc., recurring intolerant arguments about the 'best' way to do anything, vanity posts from folks who think we're interested in their opinions about just about everything, etc. It just seems that seven or eight people have 'taken over' the list as a forum for their often lengthy and OT opinions and arguments, while I see familiar people with much to contribute leaving and appearing on other lists instead and citing the above 'noise' as the reason (not to mention the folks still here begging them to keep it down and on topic). A shame IMO. m

Tally 2000 printer free for pickup

by jdbryan＠acm.org

I am the original owner of a Tally 2000 line printer that is free for pickup in the Baltimore, MD (USA) area. The printer has a 128 character set, a parallel differential interface, and was in regular use with an HP 1000 minicomputer from 1977 until it was decommissioned in 1994. Since then, it has been stored in a heated and air conditioned office pending refurbishing, which I no longer have the time to perform. At decommissioning, the printer was operational but was beginning to substitute characters, probably due to an error in the logic of one of the character data lines. The HP 2607 was a rebadged Tally 2000. The printer is complete with a stand, wire paper basket, and operator and service manuals. Weight is approximately 150 pounds. Due to an office move, it must go by June 29th or it will be scrapped. The operator's manual is online here: http://www.hpmuseum.net/document.php?hwfile=4090 I'd prefer to see it go to a good home rather than being pushed off our dock into the dumpster. If you're interested in picking this unit up, please contact me at <jdbryan at acm.org>. -- Dave

IBM 5150 or 5170 reference PDFs?

by brain＠jbrain.com

I'm trying to add XT KB support to a project here, and I am having trouble sorting out a few scan codes. A response over at the VC Forum notes I should grab these two references, so I am wondering if anyone has a link or soft copy. I created my PS2/XT mapping using this matrix: http://ilkerf.tripod.com/c64tower/F_Keyboard_FAQ.html#KEYBOARDFAQ_037 And that matches up with ChukG's AT2XT project, except for '\' (the link has it as decimal 29, Chuck's project has it at 42, and he has 0x61 PS/2 code mapped to decimal 45 XT code. I don't know either of those codes. But, that mapping does not match up with most of the maps on the net. Jim -- Jim Brain brain at jbrain.com www.jbrain.com

Decwriter power supply transistors R3004

by brian＠quarterbyte.com

Hi all, The LA-120 Decwriter that I got off Craigslist a couple of weeks ago has a dead H7150 power supply. Transistors Q1 and Q2 are open and shorted, respectively, and fusible resistor R4 is open. I'd guess that the failure of Q2 took out the other two parts. Q1 and Q2 are high voltage NPN power transistors in TO-3 cans, labeled __ 81 [ti logo] 41 (or maybe 4I, no matter, it's a date code) R3004 BRITAIN The DEC part number is 15-12782-00. The printset identifies them as "NPN 100W S1325 15". I can't find any substitutions online for either R3004 or S1325. (Or 15-12782-00 for that matter). There is a NOS pair for sale on eBay. So that's one option. Does anyone know what the modern equivalent(s) are? And what if you do, where did you find the reference? Thanks, Brian

MS-DOS/MSCDEX wierdness

by pete＠dunnington.plus.com

I have a PC used (or at least intended) for floppy transfers, which has a hard drive booting MS-DOS 6.22, with an 80-track 5.25" drive and a 3.5" drive connected to a WDAT-240 controller. It has the MS-DOS network stuff installed so I can connect to a shared network drive. It's also got a CDROM drive on its second IDE bus, and the corresponding lines for the driver and MSCDEX are in CONFIG.SYS and AUTOEXEC.BAT. Most of the drivers etc are loaded in high memory (I ran MEMMAKER in the dim and distant past). At the moment, those two lines are commented out because if they're not, the floppies don't work properly. Has anyone got any idea why? The CDROM works fine if I uncomment those lines (but the floppies don't) and network shares work fine either way. -- Pete Peter Turnbull Network Manager University of York

Dropping offline for a bit.

by BHuntsman＠mail2.cu-portland.edu

Well, I for one enjoy that you consistently add value, so don't drop off for too long. Also, while you're off the main list, don't forget about that 3B2, and let me know if you catch wind of a 3290... :) hehe. Thanks much, as always! -Ben ________________________________________ From: cctalk-bounces at classiccmp.org [cctalk-bounces at classiccmp.org] on behalf of Dave McGuire [mcguire at neurotica.com] Sent: Sunday, June 16, 2013 1:44 PM To: On-Topic and Off-Topic Posts Subject: Dropping offline for a bit. The jerk factor on this list has become so high of late, and the clue factor so low, that I will take a respite for a bit. It seems I can no longer resist the attempts by jerks to get a rise out of me. Actually, I should say the "rise-able" people here in general, as I don't feel singled out, except by Mike Stein this morning...I'm just a bit more "rise-able" than I should be. But either way, for that I apologize. I'll be back when my stress level drops a bit, or when the jerks leave, and when there's something to talk about. -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Amusing statistic

by dm561＠torfree.net

I was curious... Out of 143 people who posted to the list in the first half of June, 116 posted 5 times or less. On the other hand, only 9 people (and we know who they are ;-) are responsible for half (462) of the total 923 posts, with Dave easily the winner... Must be nice to have so much time to waste...

IBM 5150 or 5170 reference PDFs?

by jce＠seasip.demon.co.uk

There are a number of problems with describing scancodes unambiguously, particularly when it comes to the backslash. Depending on the layout, it could be found at: Scancode in set | 1 | 2 | 3 | --------------------------------------------------+----+----+----+ * The key above "Tab" | 29 | 0E | 0E | * The key between "=" and "Backspace" | 7D | 6A | 5D | * The key below "Backspace" and above "Return" | 2B | 5D | 5C | * The key to the left of "Return" | 2B | 5D | 53 | * The key between "Left Shift" and "Z" | 56 | 61 | 13 | --------------------------------------------------+----+----+----+ An 84-key AT keyboard will return the Set 3 codes for these positions. -- John Elliott

You can tell someone you got a sum total > of $300 for all the pieces when they assured you you'd only get $100 > for the original. Of course. Unless it's a 'real' classic like the Apple I, most of the time just a few parts will sell more easily and for more money than the system they came out of, especially with today's shipping costs and hassle, so from a financial perspective it makes a lot of sense to part out. Even from the hobbyist perspective it make sense to make parts available; often scrapping one machine will yield the parts to get three or four other machines running again. And of course the very people who condemn folks for breaking systems down for parts are often the first to snap up those parts when they need them... m
