Unlike the IMSAI flat toggle switches it had the triangular ones like DEC PDP-15s. Personally I preferred the IMSAI ones (memories of bloody fingers after toggling in a long binary on an Altair front panel with it's knife edged switches). The DPS-1 works but the motherboard connectors are shot...I got it from a plating/foundry company, covered with crud from the sufuric acid vats next to it. Now if anyone has a nice new pristine Morrow 20 slot motherboard to replace the "etched" one... The other nice feature of the DPS-1 was an o-scope trigger mode on the front panel, sort of a poor man's one channel logic analyzer. If I remember correctly, it also knew something about 24-bit addresses.

Computers that have appreciated (RE: Altair price check)

[SMTP:yowza@yowza.com] > Besides the Apple 1, does anybody know of a computer system that has > actually appreciated in value? :-) > I assume you mean machines that are worth more than their original purchase price. That would be a pretty short list... notably: - IMSAI 8080 (assuming a base system; a fully configured setup would have cost thousands) - MOSTech KIM-1 (it was so cheap originally it can hardly avoid appreciating since it's a significant historical piece) - Rockwell AIM-65 (ditto) - RCA COSMAC VIP (ditto) If we adjust 1970s dollars to today's rate, not even the Altairs go for more than the purchase price. That leaves only the Apple I in the appreciating column. The only other micro systems (besides the Altair 8800s & Apple I) that fetch significant money, but are nowhere near appreciating from original cost, are: - IBM 5100 - Altair 680 - Processor Technology SOL - Commodore PET (chiclet version) - Apple Lisa - Unproduced prototypes of Atari 8-bit or Commodore equipment Kai

front panels

Was that just a display driven from a boot ROM or was it a real front panel, with displays directly driven from the bus, examine/deposit, single step, etc.? Usually a hex keypad meant a simulated front panel (CPU actually running a debug program in the boot ROM). A true front panel needed 16 LEDs or 4 hex digits for address, 8 LEDs or 2 hex digits for data, and at least 8 status LEDs for bus signals (SINP, SOUT, MEMR, INTA, etc.). All the panels I have seen also had an extra 8 LED latched output port and sense switch input port. >From cad at Mon Feb 23 17:06:14 1998 From: cad at (Charles A.

It's a full-and-a-half-length S-100 Z80 single board computer card (it's so long, it couldn't have fit in any case) with several segments of alpha display, and a 24- or 30-key keyboard-style keypad.

Panasonic Exec. Partner information wanted

by Marty＠itgonline.com

I was just given a Panasonic Exec. Partner. It looks like a laptop on stearoids. It should have been called a lugtop. It has a red plasma display, full keyboard, twin 5 1/4" floppy drives and a built-in printer. It comes with a convenient folding handle that swings out of the way (so as to not destroy its sleek lines presumeably) and boots fine. Unfortunately no paper came with it so I'd appreciate any information on when this was marketed. It's PC DOS compatible so that dates it post 1981 at least. Marty Mintzell

I looked at the code, and discovered a few things that the owner of that page (Tim Olmstead) hadn't found. I think CP/M-68K was cross-compiled under Alcyon C on a VAX 11/780. (Alcyon also produced an OS called Regulus that was available for Smoke Signal Broadcasting's 68000 systems.) The source contains the name "Tom Saulpaugh", and a web search turned up a book "The JavaOS? Design and Architecture" he wrote. He's at Sun as the architect of JavaOS for Network Computers. Tom Mason also works at Sun, and he worked at DRI on CPM-86, Concurrent CPM-86, and CP/M-86+. Novell appears willing to release source, but Tim suspects that there's no one around willing to discover or document what's available - if anything. For example, the source to CBASIC should be around, but they haven't released it. - John Jefferson Computer Museum <http://www.threedee.com/jcm>

BBC Model B - video help

by Philip.Belben＠powertech.co.uk

On the subject of BBC video problems, it occurs to me that the BBC micro does scrolling by moving the pointer to the start of the screen (under some conditions?). If you can get it to do this, and see how the display behaves, you may be able to determine easily if it's an addressing problem. Just a thought. Philip.

RQDX3 problem?

by allisonp＠world.std.com

<Is it possible for a RQDX3 to be bad, and trash a RD53 (Yes, I know what <terrible drives they are) to the extent they can't be formated in a VS200 Yes and no. Yes I've had drives a VS2k would not touch but the drives were otherwise ok. The PDP-11 formatter would however format them. Most of the drives I have that the VS2k didn't like were formatted on my CP/M crate using a teltek card(oddball format) or the older PC mfm controllers. You could have an incorrect hookup, power problems or other things going on. Are the RD5x's powered from the same powersupply as the rest of the system (in the same box)? RQDX3s do fail though the failure modes can be vary varied as they have their own PDP-11/memory/eprom on board. If it passes self diagnostics it's a 98% safe bet, if it's self testable it's ok. That does mean there are parts that selftest cannot verify. <So my question is, am I just having very bad luck or is the controller m <problem? I think your suffering from a multitude of things and with an apparent lack of docs to reference too. Your trying to attack it was if it were a PC and it's not even close. Those drives generally don't fail that suddenly and my expereince is they are generally reliable. But when you start with a box of junk it's hard to get to a know working point. Me I have Q-bus PDP-11s that can boot faster and off a wider variety of devices so any testing is done that using good old RT-11. I also have a set of diags for that platform so testing things like disks, tapes and interfaces is doable either with diags or by using them. At some point I have know good boards and questionable seperated and can move the known good to the uvax. PDP-11 and uvax Qbus commonality can be handy. Allison

RQDX3 problem?

by healyzh＠ix.netcom.com

Is it possible for a RQDX3 to be bad, and trash a RD53 (Yes, I know what terrible drives they are) to the extent they can't be formated in a VS2000? I'm still trying to get my VAXstation II/RC up and running, and I was trying to load it with a questionable tape today. I booted with a standalone backup tape and started reloading. I then proceeded to get a parity error, which I told it to ignore. It sat around for a couple of hours not doing much of anything, so I halted the system and unloaded the tape. Then later on today I went to load it from a known good system tape, only this time standalone backup wouldn't see the disk. Thinking the drive needed reformated I pulled it out, and put it in my VS2000, and when I go to format it I get the following. >>> t 70 KA410-A RDRXfmt VSfmt_QUE_unitno (0-2) ? 0 VSfmt_STS_Siz .?? VSfmt_RES_ERR #2 84 FAIL >>> I had formated this same drive in this same system early last week with no problem. I just hadn't had time until today to try loading it. This is the second Hard Drive that has quite working and I've been unable to format after placing it in this system. I have yet to actually get the system to work with a Hard Drive (although the standalone backup recognized the one earlier today). So my question is, am I just having very bad luck or is the controller my problem? Thanks, Zane | Zane H.

RCA CDP 1802 & SC/MP parts

by jmg＠iac.net

Hey! I just landed pieces to an 1802 kit! I've got everything but the hex keypoad and power supply (though I'm sure +12, +5, -5 would do the trick). This is not one of those single board computers like the ELF-II, it's made up of several boards which connect to the main unit via ribbon cables. Here are descriptions of the boards: Primary board with 1802 labled "Infinite" Part Number UCE100001 dated 1976 This board has a rather large crystal which appears to run at 135khz (if I'm reading the markings right). A large blue 3000 MFD capacitor, some smaller disk .01 uf capacitors, and these chips: 4) RCA 701 CD4001AE 1) RCA 631 4049AE 2) 2606B (I think this is the 256 bytes of RAM) The board also has a two sided 36 connector per side edge card, which connects to nothing. Next to the 1802 is a red ribbon cable which attaches to another board containing four LED readouts and a singfle LED light (attached to the Q bit I suppose). Each LED (but the Q light) has F9368DC 7705 - one for each LED). The second board is listed as INFINITE 1976, UCE30004. On an unattached board are two LED's, four chips and a 24 pin socket (empty - I guess for a monitor ROM). This chips are: 2) RCA 701 CD4001AE 1) M1-0110-5 (7649) 1) MC14013CP (7438) The last unattached board contains three switches and three buttons, with a metal faceplate labeled UC 1800. The buttons are labeled Reset, Start/EF1, and Enter, the switched are labeled ON/OFF, STNDBY Power, and Load Mode. This board also has four chips: 3) MC14013CP (7438) 1) RCA 636 CD4011AE Both of the unattached boards connect to the primary board via a ribbon cable terminated by a 14 pin DIP; there are two 14 pin DIP sockets on the primary board. It's unclear which board should be plugged into which socket. I also snagged pices to an SC/MP kit, along with a bunch of DOCS and old COMPUTE newsletters dating from 1978 or so (WOW!). Also got a COSMAC Microprocessor Product Guide (think I could call up RCA and order any of the things listed therein????? - HA!), and an original RCA 1800 Users manual (WOW!), in almost pristine condition. As a kid I put together an ELF-II in 1980 (I was 12), so I have some familiararity with this line of processors (could never get over the gethi instruction yuck yuck yuck). Looks like I need to put together a hex keypad and P/S to get this up and running. Anyone have any ideas? Also, this things is missing the CDP 1861 video driver which my old ELF-II used to have - what's up with this? I wonder what happened to all those old late 70's kit manufacturers... I don't see any FAQs out on the net for those old ELF's, KIMS, SYMS, and AIMS. Oh well, relpies by the curious and knowledgeable would be most appriciated. Thanks! J. Maynard Gelinas

I got some more stuff! :-)

by rexstout＠ptld.uswest.net

Well, at the hamfest yesterday I got a VT220 terminal, an HP-IL/HP-IB converter(maybe now I can use my HP 2225B...), a Laser 128 with two monitors(broken Zenith and working Apple Monitor III) two disk drives(Apple Disk II and a clone) a box of Apple II cards(mostly printer cards), a Hayes Micromodem II(110/300bps switchable, Apple II card and a box that sits outside the computer), two huge 9600bps leased line modems(kinda useless, but they were free!), an IBM 3180 terminal keyboard(but no terminal...), and of course I couldn't leave without getting a battery for my TH-205 radio. Everything seems to work except the VT220 keyboard and the Zenith monitor, and I have no way of testing the modems but they ligth up when plugged in, and I'm hoping that the 3180 keyboard will work with my 3191... -JR http://members.tripod.com/~jrollins/index.html - Computers http://www.geocities.com/Area51/Lair/1681/ - Star Trek

Tandy/Radio Shack Model 12

by gpine＠popmail.mcs.net

I have a non-working Radio Shack Model 12 computer, some software, and some documentation that I would gladly give to someone who could use them. I don't think that the unit would be worth the cost of shipping as the computer is probably useful only for parts for someone who has one already. I know that one disk drive (it has two 8-inch drives) is bad. It was physically ruining diskettes by scraping off the coating in a ring toward the center of the diskette. In the process of inspecting the unit to check out the drives, I managed to break off a nub of glass near the CRT socket and the vacuum seal was broken. If someone wanted to fix this unit, he would need one good 8-inch, half height drive and a new CRT. So far as I know it has one good drive, a good motherboard, power supply, keyboard, and whatever other electronic boards as might exist (I don't remember). The computer was working at the time I finished it off mechanically except for the bad disk drive. I also have the Model 12 Owner's Manual and TRSDOS-II Reference Manual, a brand new copy of TRSDOS 2.0B Version 02.0B.00 from Radio Shack special orders dept., a copy of Pickles and Trout CP/M for the Model 12, and a copy of SuperCalc 2 with P&T CP/M. I also have a plastic dust cover for the Model 12. I live in the Chicago area. If anyone is interested in picking up the unit, send me an email, and we'll make arrangements. If someone wants the unit enough to pay the cost of packing and shipping via Mailboxes Etc., I'll check into costs, but I doubt that it would be a good investment. Let me know of any interest.

the 9533 i had was preloaded with os2 but now i'm running pcdos7 and win3.11 just fine. i trying to get a pcmcia nic to work but having problems. the nic worked in my thinkpad but i dont remember how i had my autoexec.bat and config.sys set up. i do not remember the memory inclusions and exclusions that need to be set up. david << What kind of networking problems are you having? Do you have the PCMCIA model? Some of them had a token ring card instead of PCMCIA. Obligatory 10-year-old-plus story: HSC also has a DG/One (I think they want $45 for it) and an odd-looking Morrow portable that wasn't in very good shape.

Datanumerics DL8a

by adavie＠mad.scientist.com

I asked about this one a little while back. Nobody knows what it is, apparently. Datanumerics DL8A. It is 8080 based, comes in a 19" rack mount case, has 4k 600ns ram, 1 current loop (I think) port, and obviously a full front panel. I ended up paying about US$150 for the DL8A, a Compucolor 2, and a PET 2032 A log? Maybe, but I'm curious about the DL8A. If there's any interest, I'll place images on my website when it arrives. A.

ah, the 9533! i bought two nonworking ones for $30 and fixed them both! i gave one to my brother that is still in warranty for two more months. these machines have 3 year warranty and some are still under warranty. Im having problems getting a nic to work, but a cute little machine nonetheless. i love the keyboard too. i have never seen the matching lcd though. david In a message dated 98-02-20 01:06:49 EST, you write: << > All PS/2 starts with 85aa-yyy, Not all of them. One of my favorite odd-ball computers is the IBM PS/2e (9533). It's a very small low-power desktop model with 4 PCMCIA slots. One of mine even has an external flat panel VGA display. Because of the low power consumption, I use one as my home LAN internet gateway. BTW, does anybody have an extra floppy and cable for one of these things? It uses a notebook floppy drive and a notebook-like cable (mylar?). >>

PCjr serial connector pin out

by jdemaa17＠calvin.edu

We are looking to convert a PCjr computer into a serial terminal emulator, and our limiting factor is finding how to adapting its serial connector to a DB-9. Has anyone done this? We do not want to spend money on this, this is a student project. I apoligize for butting into this list as I can't find how to subscribe, so please reply by personal email. Also, if anyone knows of a good dos program to use for this project, please let me know Jeff DeMaagd jdemaa17 !at! calvin.edu http://www.calvin.edu/~jdemaa17 64-bit Alpha Linux OS user.

If you think that's cool, you need to check out what they are doing with QNX: http://www.qnx.com/iat/createdemo.html QNX is a very small micro-kernel OS that has the look of Windows 95, has builtin TCP/IP networking, a notepad, a few other little doodads, and to top it off, a fully functional HTML 3.2 compliant web browser. Also supports graphics modes up to 1024x768 in millions of colors. Okay, not amazing enough for you already? How about if I told you it all ran off a 1.44mb floppy disk? Hmmmm? :) Everyone owes to themselves to go grab this FREE (yes, FREE) OS and try it for themselves. -John Higginbotham- -limbo.netpath.net-

IBM docs.

by Philip.Belben＠powertech.co.uk

At the risk of reviving at least two discussions better left dead, I have dug out some more IBM documents. I have a 4361 marketing leaflet - the 4361 was the entry level 370 system between the withdrawal of the 4341/4321 and the introduction of the 9370. I have practically no technical info so it won't contribute to the debate on power requirements, but it was a self contained, air-cooled unit often described as looking like a chest freezer. I also have the following pocket reference cards/books. IBM System/34 Command and OCL Statements Reference Summary (9th edition, April 1983), 170 pages IBM System/34 COBOL Reference Summary (4th edition, January 1982), 90 pages IBM System/34 Assembler Reference Summary (3rd edition, July 1979), 26 pages IBM System/32 SCP Command Statement Reference Summary (6th edition, May 1980), 23 pages It seems I have a second copy of the Command and OCL statements and Cobol reference summaries. *** IF ONE OF YOU OUT THERE WITH A SYSTEM/34 NEEDS EITHER OF THESE I WILL SEND IT/THEM TO YOU *** I might also photocopy the Assembler reference if you ask nicely. If anyone out there has a System/32 I shall be so amazed I might even send you my only copy of the reference card. The instruction set of the System/34 looks CISC and 8-bit-ish, although it handled 16 bit and (I think) 32 bit data. Typical speed seems to have been 0.1 to 0.3 MIPS. Someone on this list some months ago described it as "a room-sized 8088" which is probably about right, performance-wise... Philip.

9370 is a dog! Was: Re: Re[2]: Firsts

by Philip.Belben＠powertech.co.uk

[Power Consumption of 3090] > Are these all water machines? There are some air-cooled versions that are > probably reasonable. All 3090 models are indeed water machines. The 3090 was IBM's large mainframe of the late 1980s. There were other 370-derived machines around at the time. In particular there was the 4300 series, of which the 4361 and 4381 remained at that time (I think if you tried to buy a 4321 or 4341 you got a 4361. The price was the same, anyway.) I cannot remember whether these were air or water cooled, but they were much less powerful than the 3090 >> These figures are not even for a minimum system - you have to add disk >> drives and that awful 400Hz motor generator set - which can consume up >> to 7kW in itself. > > Yes, the 400 Hz would be a problem, almost as much as a cooling system (if > one went with a water machine - probably too big of a headache). I wonder. I have never seen inside the PSU of any of these machines, but it seems to me that the outputs are all going to be low voltage dc at a few hundred amps - so conventional switching power supplies could be contrived (tho' probably not purchased new if there are tens of kW involved!) to replace the strange 400Hz thingies. And a little circuit to provide a 400Hz heartbeat if the machine uses this at all... >> So, as I said, a typical system based around, say, a model 200 might >> consume 50kW, but even that needn't cripple you financially. > > No. Around me, electricity is not very cheap - 11 cents/kWh - but running Much the same here. > a 50kW computer is not a financial burden if done in moderation. What > might be a burden is getting the service entrance of the house to a point > where it could handle 50kW nicely. Yes. Although the elctricity company may do a lot of the work free of charge if they think you're going to use a lot of the stuff. (My parents achieved this. They wanted to move the meter board, so the electrician doing the wiring told the electricity company, they're going to use so much electricity thy'll need 3-phase and there won't be room in the existing location. Result: new 3-phase connection and new meter board, all free of charge.) > I suppose that is the good thing about RCS/RI - we are in a factory, and > are looking to get real 3-phase installed! Nice. I'm surprised you don't have this already if you're in a factory. Here we have 240V (now officially 230V but I've not noticed any change) single phase up to around 20kW peak demand, 415V 3 phase (now officially 400V, ditto) up to a megawatt or so, 11kV 3 phase above that. Some factories have their own supply at 33kV or even higher. Philip.
