Speaking of PS/2s...

by ajp166＠bellatlantic.net

I have a PS2 50Z I use as I have an HP scanner and interface for it. Nice machine though at 1mb it's kinda tight for memory even by 286 standards. The upside is I have OS/2 V3 warp for it. Allison

NCR 386/486 UNIX - Anyone remember this?

by msell＠ontimesupport.com

Guys, My wife recently got a job at a bridal retail chain that uses NCR 386/486 UNIX for the POS terminals and financial matters relating to the operation of the store. It's running on what appears to be an NCR 386 (or 486?) with a tape backup, and services four WYSE terminals and a printer. Seems to be a standard setup for the stores in this chain. There is also a WYSE CE terminal connected via ADSL to a Citrix server - but that is naturally a piece of sh*t. Always crashing. Situation normal for Windows. Just curious if anyone here has had experience with this flavor of UNIX. I used to work at Radio Shack and at the time we ran the entire store from a 386 running XENIX. It handled *EVERYTHING*. Performance of the whole system was quite impressive. This NCR system seems to be rock solid and has decent performance. Just curious. It's neat to see something other than Windows "in the wild". - Matt Matthew Sell Programmer On Time Support, Inc. www.ontimesupport.com (281) 296-6066 Join the Metrology Software discussion group METLIST! http://www.ontimesupport.com/cgi-bin/mojo/mojo.cgi "One World, One Web, One Program" - Microsoft Promotional Ad "Ein Volk, Ein Reich, Ein Fuhrer" - Adolf Hitler Many thanks for this tagline to a fellow RGVAC'er...

Hardest to Find Classic Computers (SX64)

by CLeyson＠aol.com

Cameron Kaiser wrote: > Awwww, c'mon. Wizball brings a smile to everyone's face. One of the best games of all time. I never really got into the C64, I was too busy building disk drive controller boards for the Atari or trying to get fig forth to run. Sad but true :-( The C64 was a really neat machine but had a few hardware reliability problems. The PAL and the graphics chip were prone to early failure. At one time I used to fix two or three machines a week for a friend who owned a TV repair shop. He bought scrap machines from high street dealers and I would end up having to fix them. However, some of the games for these machines were works of genius. I really admire the people who had to write the software, mostly in assembler, and too impossible deadlines. The same could be said for the "speccy". Not exactly reliable but for three chips, Z80, current injection logic ASIC, sound and some DRAM - WOW ! The cassette interface could be a problem but when faced with the prospect of having to rebuild DC100 tapes, ( including drilling holes in the tape ), and replacing the drive wheel in an HP tape drive - I'd go for the "speccy".

More Power Series

by csmith＠amdocs.com

Hi again, I neglected to mention in my last power series post the odd video connectors on this thing: 1 analog video in/out breakout plug. (The same as the plug for the Galileo breakout, I believe) 2 "Digital video out" plugs. (They look like 25-pin or so parallel plugs, female) 7 BNCs. I assume 4 of them are the R, G, B, and S for the monitor. The others are labeled "Alpha," and are also red, green, and blue. What do I do with them? :) Regards, Chris Christopher Smith, Perl Developer Amdocs - Champaign, IL /usr/bin/perl -e ' print((~"\x95\xc4\xe3"^"Just Another Perl Hacker.")."\x08!\n"); '

[OT] SynOptics 810M PowerSupply problems

by sipke＠wxs.nl

Hi Folks, Propably not yet 10y old so slightly OT. yet ..... I got a SynOptics 810M ethernethub about 9 month ago and it served me fine till two weeks back. When I came home all the power was down because the groundleak protection was triggerd. Eventually it turned out to be the powersupply of this hub that went bad on me. I want to replace it with another psu but I can't find any info on the way the ps2-like powerplug is wired. The 810M needs +5V +12V -12V 0V and ground connections. Does anyone, familiar with this device, have a clue ??? Sipke de Wal ---------------------------------------------------- http://xgistor.ath.cx ----------------------------------------------------

MITS 2SIO serial chip?

by ajp166＠bellatlantic.net

From: Ben Franchuk <bfranchuk(a)jetnet.ab.ca> >True. The only real trick I used was on reset. This would clear >the instruction register and state counter to zero. I would then Reset for the approach I took was simple...clear the ucode latchs. the reset(restart) addres in ucode was 000h. >use that to fetch the first instruction. All instructions would >start from state 2. IRQ was jam on the bus the IRQ instruction. >This has changed slightly as of today since I did add a irq input >and made reset now load a octal bootstrap. IRQ was simple too.. the first microinstruction for the normal machine cycle was opcode fetch... unless the IRQ FF was set then the microaddress loaded was interrupt action address rather than the mapped opcode. That meant the interrupt system was synchronized to instruction fetch and also the actions taken were what ever ucode dictated. IRQ and CALL were the same basic ucode obviously. Other things I played with is a JSR (pdp-8 style) and CALL(stack style like z80 and others). Both had advantages but the JSR style was easier to make fast in ucode{fewer microwords}. >I have looked a microcode but not having a PROM burner kept me from >doing anything with it. I found I spent more time writing software >and emulators than thinking about hardware in great detail. >Most of the fixing of bent opcodes have been done before I did the >hardware but I did make a few changes in the exact opcode order. At the time I did it (1981ish) the emulator would have to run on either CP/M z80, RT-11(PDP-11) or my fingers. Part of the opcode thing was design, test, then play what if. At that time I used 350ns 2732s as I had them and could easily burn them, not fast but, easy to use. Also all the ucode for lack of a compiler was hand written. The approach was modular, simple and as much of the circuits repetitive to make wiring (wire wrap) easy to do and troubleshoot. For example the microstate machine was tested with one 2732, one LS273, one 74153 and a debounced pushbutton. That allowed me to investigate things like micro jumps, looping and startup. From there it was pretty easy to add more bits to control other logic like RAM, ALU and bus traffic latches. Using 2901s with that microcontroller was a fairly simple, expandable and managable machine of moderate speed by 1981 standards. Still it was fairly large and ate power! One for the experimental machines tried with that hardware was a 1802 like register based cpu with 16 registers like 1802 but the ALU and data paths were also 16bits. Even simple changes like that have interesting effects on in instruction sets and addressing modes. For example the 1802 does not have instructions for loading or storing the 16bit register content, you have to move bytes through the Accumulator due to 8bit busses (even internal). Once you have a 16bit path other things make more sense(or less!). Allison

OT: GatorStar GX-R....

by DAW＠yalepress3.unipress.yale.edu

Yes, this box is not quite old enough, but it is an AppleTalk & LocalTalk Router. The protocols probably do classify as "Classic". Anyway, Cayman.com doesn't have docs online anymore for this, and I'm gonna try calling/e-mailing them right after this is sent. Does anyone else have a user's guide, and/or reference guide for this? So far Google is turning up only 'How-To' for setting it up. I'd like to get my hans on the paper guides that shipped with it. At least a copy, or something... --- David A Woyciesjes --- C & IS Support Specialist --- Yale University Press --- mailto:david.woyciesjes@yale.edu --- (203) 432-0953 --- ICQ # - 905818

OK, Bill, you wanted a PCI-based RS/6000? One of our clients is trading up to an H80, and IBM just lowballed them on their trade-in. They're putting thei old server on the market. It ain't a classic or even uncommon, but I thought some of you guys might be interested. S70A 4-way 4G RAM SSA - just adapters, they're keeping the drawer. 8 ethernet adapters, IIRC. 2 10/100, 6 10bT, subject to my CRAFT Syndrome PCI graphics, I think GXT120. They're looking at about a $10,000 price tag, and a March 1 release date. This guy has been lovingly & lavishly maintained. Anybody interested can contact me for detailed specs. Doc

Apple Scribe Printer

by mythtech＠Mac.com

I aquired an Apple Scribe printer last night (went back to the Thrift Store and they hadn't repriced it, so I asked, and the guy let me have it for $2). It worked briefly, it printed the first 4 lines of a test pattern and then jammed. It looks like it may just need to be greased (the print carriage is really hard to slide by hand, but not so hard that I am hitting motor resistance, I just think after all these years, the guide bar may have dried up enough). But, before I get into opening it and regreasing it... I was seeing if anyone had a manual for it and can tell me what the blinking light indicates. When I turn it on, the Select Light blinks in patterns of three (three blinks, pause, three blinks, pause...). I did a quick google search, didn't turn up much (but found some places to buy a new ribbon, and found a few "museum" listings for it). Apple's TIL also didn't cover the lights (but has some control info so I can see if I can get it to work with one of my computers). Finally, does anyone know if there was ever a Mac driver for it? Or if the Imagewriter driver will work with it? Apple's TIL seemed to indicate it was just for the Apple II series (they leaned towards talking about the IIc in conjunction with it, but since everything seemed to say the application in use is what drives it, I would think just about any Apple II with a serial card should be able to work with it). I do know the archives showed someone else on the list found one of these back in June, but there wasn't much said about it. TIA -c

Bent in that you might want a load to always be some opcode and a logic change down stream makes it something different do to gating. A PLA or Prom to translate opcodes from a irregular pattern of hardware convenience to something regular is handy. Besides with 48 bits of ucode the address of the next instruction is in the ucode and the logic is a really wide prom with a really wide latch and a really simple next address select logic (some LS257s). No counters or incrementors, The translated opcode from the prom was the source of the high order ucode address after a "next instuction fetch". Made the ucode very simple though not very efficient in terms of bits. Eproms though slow made it cheap with bipolar proms as follow up for speed. Allison

There are two things the 765 will not do: Munged wacky formats like using deleted address mark for address mark {you can post format with deleted data} and it was not designed to pump out all the raw bits/splices/marks from the media. Things it did do that the WD never had: Multiple seeks or recals, timing for the stepper, head load delay, head settle delay. The biggest difference: register based programming vs command packet to a "port". I've used both and someplaces one or the other is better. On the whole the WD parts always seemed to be first generation. The upside for the 765 based was the very highly integrated super chips like the 36c766 and later. Allison

Was it just the MBR that got nuked? Lots of times on intel systems, those are similar if not identical. All the boot-loader magic is handled in the second-stage loader near the beginning of the partition, or something like that. :) If that is the case, you may be able to replace it with the MBR from an MS-DOS bootable hard-disk. Also the DOS command FDISK/MBR is known to restore the MBR to such a state that at least MS-DOS will boot. If Xenix expected the standard DOS MBR, you'd be all set. So you could try making an MS-DOS bootable floppy, copying FDISK.EXE to the floppy, booting the machine from that and running the command. If the Xenix MBR really is different, then you may still be able to get away with using the DOS loader, provided there's a second-stage boot-loader in the right place on the Xenix partition. You would just use FDISK to set the bootable partition flag on the partition you'd like to boot, and the DOS boot-loader will try to pass control to a second-stage on that partition. Once you got in, of course, you could re-install the proper Xenix boot-loader (instboot?) I would back up the MBR first. I think there are utilities with most boot-loader apps that will do that. (Note that this is more-or-less speculative, but I'd like to know if you try it, and specifically, whether it works) Regards, Chris Christopher Smith, Perl Developer Amdocs - Champaign, IL /usr/bin/perl -e ' print((~"\x95\xc4\xe3"^"Just Another Perl Hacker.")."\x08!\n"); '
