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.

NorthStar Advantage Question

by maxeskin＠hotmail.com

So many Z-80 CP/M machines... were they compatible, to a reasonable extent? (I heard that MS had some standard in Japan for the purpose called MSX.

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-

<This is a CP/M master for a Vector Graphics Vector 4 CP/M machine. Was <the Vector 4 S-100 based btw anyone? < <Sam Alternate e-mail: dastar@sicon Yes it was.

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.
