I'm "just about" finished with an emulator for a Control Data 3300 computer (you might ask "why" - I'll explain later.) But I'm looking for diagnostics tapes (instruction, floating point, mass storage, memory, etc.) Also, other operating systems would be interesting (I was dumb back in the 70's and didn't make copies of all my old stuff...) such as Master with MATS or MSOS or Realtime Scope. (I have no problem reading 7 track tapes.) I'm building this primarily to resurrect an obscure language, also developed at OSU, called "Oscar". It was a numerical person's dream interactive system for it's time (way before common graphics terminals, alas) including all sorts of large precision arith and rational number management (ratios of integral fractions) which made matrix manipulations a lot easier. Oscar ran under OS-3 and hence the need for the emulator. Besides, it's fun. (And I have source for damn near all of the OS-3 system, languages and tools (I was "with it" enough to make copies of those at least.) The original 3300 at OSU was "decommissioned" back in the early 80s, so this part is even "on topic!" It's a bit depressing (and humiliating) to see that my entirely-C-based emulator (i.e. NO assembler "optimization" on my part) runs at nearly the speed of the original machine on a lowly 66 mhz 486. (1.6us/cycle where instructions USUALLY took 2 cycles, for fetch and memory reference.) It'll probably scream on a reasonable Pentium-class system. (By inference will we be writing emulators in 15 to 20 years that emulate 400 mhz Pentiums and Power PCs at the full speed of day? Boggles the mind...) I'm emulating most CDC periphs (as far as I can without real "iron") so the emulator should handle virtual 604/607 tape drives, disk controllers, 501/512 printers, card readers, punches, etc. I realize this may be a bit "off topic" with respect to the other "mainstream" collectable computers (dec/hp/etc.) but, hey! it's what I learned on way back when. And the computer was far too large to ever think of "owning" one. For reference, the 3300 was a 3rd generation computer (no IC's - all Germanium transistors) with memory that came in chunks of 8k words (24 bits) all the way up to 256k words (LOTS of boxes.) Each 8k took half a 7 foot tall by 6 foot wide rack (IIRC). I think very late in life they had 32k modules... 24 bit ones-complement math with a "reasonable" two-state architecture (program/system mode) that actually worked (OSU's may have been the only one that really challenged it, though, running timesharing software on it.) Any and all software for the beast would be welcome. For reference, anything for the 3150, 3200, 3300 or 3500 would be welcome, as well as any CDC docs on these machines. I've got quite a few, but some of the more obscure controllers (3317 terminal control, for example) eluded me. Information on 3600 or 3800 (a sort of "48 bit word" 3300 and 3500) would also be welcome, as these two lines shared a lot of peripherals and controllers. And of course, assuming anyone else is as silly as me and wants to play with this mess, I'm happy to make the source/executables available (it's Linux based.) It's not "ready for prime time" yet, but soon... Thanks for sharing the bandwidth, Gary

Thank you - I'll remember that. For non-electronic digital computers, where do Facit mechanical calculators lie? I have one (which is driven by an electric motor but could conceivably use any motor) which has algorithms for optimised decimal multiplication and non-restoring decimal division. It is not programmable, but it is pretty complex - and all done mechanically. For pneumatic computers, I think some pipe organs of the turn of the century came close - you could program some buttons to set various combinations of ranks for fast selection during performance. However, the more complicated schemes of this nature (popular around 1920) used electrical as well as pneumatic logic elements. Philip.

It's basically a message-passing protocol, unlike most of the earlier DEC disk stuff where you can poke the hardware registers to "make things happen". To oversimplify, with MSCP you make a message containing instructions, put it in a memory buffer somewhere, tell the controller it's there, and it does the rest with DMA, returning a response message. The relevant documentation is "MSCP Basic Disk Functions Manual", AA-L619A-TK, and "Storage System Diagnostics And Utility Protocol", AA-L620A-TK, which in turn are parts of the UDA50 Programmer's Documentation Kit (QP-905-GZ).

RSX-11 Disk Images anyone?

<Whether the distributed monitors and drivers are enough to run it <depends strongly on your application! Under an emulator - where If your developing with RT-11 for a specific task then sysgening is needed. If you need to run BASIC, DECUS-C, MicroPower Pascal, write assembly code files or edit text then the stock monitor are just fine. Sysgening to simply move to a different varient of PDP-11 cpu or disk however is not required. The typical example of sysgening RT-11 I've done was to use a console that wasn't DL (standard PDP-11 serial line unit) compatable. RT-11 was designed as both a development enviornment and a realtime executive for embedded applications. It's pretty flexible and small so it's good for lots of other stuff. It weakness (there is one) is that it does not use a scatter-gather map for storage so storage space can be poorly used due to device fragmentation. <I interpret "no source code" quite differently, mainly because I have <the source kits!

Definition of an Analog(ue) Computer

by Philip.Belben＠powertech.co.uk

I have just returned after a long weekend to find my mail had got set to Postpone again. This has probably all been said but I thought I'd put my bit in anyway. Tony: < A question occurred to me today : Can you have an embedded analogue < computer, and if so, how many op-amps are needed to have one? Allison > Yes, and that's very common. None, a low pass filter(RC) performs a > function and can be considered analogue. A filter made of passive components or otherwise I wouldn't consider a computer, although I agree it is definitely analogue (Americans may omit the ue where appropriate). I would say that an analogue computer: (a) combines two or more signals (b) does so in a more complex way than by simple addition or subtraction. (But this could be A+dB/dt, for example) An analogue computer need not be electrical at all - quite complex analogue functions can be implemented in cams, for example. A good example of a simple embedded analogue computer is the ignition distributor on a petrol engine. This: Takes two inputs - camshaft angle and manifold vacuum; Differentiates camshaft angle to get engine speed (centrifugal weights on springs); Applies some non linear function to engine speed (cams attached to the centrifugal weights); Adds together camshaft angle, function(engine speed) and constant * vacuum level; Compares the result with a reference angle to generate pulses of a given width for the ignition. I claim that is a simple (but actually quite sophisticated) analogue computer. < I was looking at the service manual for my Micropolis 1203 hard disk, and < I read the circuit description of the servo electronics. It's a fairly < complicated array of op-amps, which combine integral and differential < forms of the position error, positioner current, etc. I would claim that < is an embedded analogue computer. > Valid claim, also a good example of a fairly complex function. Agreed 100% (As Tony would say). An excellent example of an embedded analogue computer. Another example is the convergence circuit in a colo(u)r television. This takes the two timebases as inputs, multiplies them and their squares/ first derivatives etc. by user settable constants, and feeds this back onto the deflection systems of the tube. < On the other hand, I think it would be stretching the definition to call < a simple op-amp wired as a voltage follower an analogue computer. > Correct. However often the buffer is between some function or follows one > so it's part of the analog system. Agreed it could be part of an analogue computer. But I think Tony's point was that it does not by itself make one. Otherwise practically any analogue circuit becomes a computer (One of Vonada's axioms, I think: All circuits are amplifiers) > Other analog systems common to computers: > > cassette IO (low pass filter on output) and complex filter/differentiator > edge/peak detectors for input. Some of the acients used PLLs for clock > recovery (KANSAS City is one). > > Analog to digital conversion (quantification). > Digtial to analog conversion (filtering) > > Disk/tape systems have several layers of analog function for data and > control. Definitely analogue systems. But some are merely filters, not computers. (I think a PLL almost qualifies as a computer, though...) But in general, I agree with you both - analogue computers are often small, simple and embedded, and they're a heck of a lot more common than most people think. Philip.

Microsoft BASIC 80 non-disclosure agreement

by dastar＠wco.com

Here's an interesting artifact. I got the reference manual for Microsoft BASIC-80 (version 5) over the weekend and it still had inside the original non-disclosure registration card that I guess one was compelled to sign and send in before they could use MS BASIC. This book was distributed with some morrow system as the card is addressed to Morrow Designs Software License Department. It reads: "The party below agrees that it is receiving a copy of MICROSOFT DISK BASIC or FORTRAN for use on a single computer only, as designated on this registration form. The pary agrees that all copies of MICROSOFT DISK BASIC and FORTRAN are owned by MICROSOFT, that all copies will be strictly safeguarded against disclosure to or use by persons not authorized by MICROSOFT to use MICROSOFT DISK BASIC or FORTRAN, and that the location of all copies will be reported to MICROSOFT at MICROSOFT's request. The party may make up to two additional copies only, for back-up purposes. The party agrees that unauthorized copying or disclosure will cause great damage to MICROSOFT." Sheesh!

Convergent Voice Module

by red＠bears.org

I promised Sam I'd look this up a long time ago. I had some trouble with the phone lines, though, which made it impossible to use the modem. But here it is. I seem to have a preliminary version of the 'Voice Module' manual, although I did not get the module itself with the machine. The manual goes into a lot of detail: theory of operation, external interfaces, architecture... schematics... I'll quote from the overview: INTRODUCTION TO THE MODULE __________________________ GENERAL The Voice Processor Module, shown in Figure 1-1, provides a fully integrated voice and data interface between a workstation and the switched telephone netowrk or commonly used private automatic branche exchange (PABX) system (supporting Tip and Ring connection). When used with a digital PABX system, all signals and transmission between the Voice Processor Module and the PABX occur via analog techniques. The Voice Processor Module is an X-Bus module containing two printed-circuit boards. The first board contains a Bell 212A-compatible modem. The second board contains the following: * modular jacks for two telephone line interfaces (FCC, part 68, registered) * additional modular jack (FCC, part 68, registered) that allows connection to any standard voice unit (telephone set) * analog crosspoint switch allowing any device to connect to either line under software control * Dual-Tone Multifrequency (DTMF) touch-tone auto-dialer * DTMF touch-tone decoder that permits numeric data entry via remote voice unit touch pad * call progress tone detector * voice amplifier * Adaptive Pulse Code Modulation (ADPCM) CODEC (Coder/Decoder) for support of digitized voice communications at speeds far less than the normal 64Kbps * 8051 microprocessor to control all module activities (...excepts from following specifications...) Modem board is originate/answer, full-duplex. Supports 212A and Bell 103/113. DTMF generator generates all 16 DTMF digits, may be programmed to transmit various key sequences, and can generate single tones. CODEC and ADPCM technique allows recording/playback of digitized voice information at 6-kHz (24Kbps) or 8-kHz (32Kbps) rates. Software support is provided by CT-MAIL, CT-Net, and "Operator" software, which is specifically tailored for the Voice Module as follows: * Telephone directory management, which has the ability to add, delete, modify, and look up entries in a disk-based telephone directory, and automatically establish calls using the information in the directory. Menus provide assistance in accessing special functions used by PABXs. * Voice digitization, which allows the operator to use the CODEC to record and play back calls or messages. This capability enhances CT-MAIL, where it is used for voice annotation of written documents, as well as the inclusion of voice attatchments to textual mail. * Telephone answering, which allows an unattended system to automatically answer the telephone and perform a variety of user-selectable operations ranging from simple messatge playback/recording to input of numeric data from a telephone touch-tone pad. There you have it. All typos are my responsibility. ok r.

HDD died in a spectacular way

by manney＠lrbcg.com

I recently bought a Maxtor IDE along with other HDDs at a hamfest. When I got it home, I noticed that it "clunked". No response when I hooked it up, so, I took it apart... The head had gouged its way through the entire thickness of the platter; the remaining part of the platter was lying loose around the hub! It must have made a horrible screeching sound for days (months?), but I guess no-one noticed. The head is ground away, of course, but the arm's still intact. Anyone ever seen a worse failure? manney(a)lrbcg.com

(I never got further than realizing that the mouse was generating an error on boot, and never made a loopback connector to go further.) Anyone that's interested, reply via email...

Fujitsu Eagle

OK, got farther... (RSTS 8.0-07 + RA92)

by DSEAGRAV＠toad.xkl.com

Now the RA is hardware visible. As opposed to the RA81, where you CAN'T plug it straight into the controller, the RA92 likes that. Go figure. Anyway, I boot up and say HARDWR LIST. It sees 2 devices off the UDA50, the RA81 and the RA92. It identifies the RA92 as a RA92 also. Now, I try to DSKINT the 92. I get to where it asks me for pack clustersize. The default here is 32. When I type 32, it says ?Illegal clustersize specified and prompts me again. Nothing works. Apparently 32 is too big a number, but it's the required number, so I've shot myself in the foot. Is this a known bug? Have I screwed up here? Is there something I can change in RAM to let me go ahead? I can't find any mention of this anywhere.... -------

I guess RSTS doesn't like RA92s...

by DSEAGRAV＠toad.xkl.com

I dragged the RA92 up here, plugged it in as DU1, and started RSTS, but RSTS says DU1 doesn't exist. This is RSTS/E v8.0-07. Is there some trick to do to make the RA92 work, or am I up a creek?

Ok, what do you all know about the Wang PC XC3-2 circa 1984? I got one today. Unfortunately it was just the system itself with no documentation, but I did get some software. This one has a 5.25" disk drive and a half-height hard drive.

With all this talk of hard drives slicing themselves and adjacent walls to pieces, how is it that the motor can spin up to such a high speed when it's not supposed to, and why doesn't the head dragging on the disk surface cause it to stop?

Easy way to find out is to try it :-) There's a small amount of data on TEAC's web site, http://www.teac.com/dsp/fd/fd_55.html but that's really for the -R series which are newer. I've got jumper and setting info for the GFR (similar to RX33) and a little info on the FD55-FB and FD55-BVU (40 trk DS) and FD55-GFV-17 (HD 80 trk). TEAC also have a faxback service, and there's a catalogue of the faxback documents at http://www.teac.com/dsp/catalog.html You could try http://www.psyber.com/~tcj as well. -- Pete Peter Turnbull Dept. of Computer Science University of York

Head draging...? only if it's crashed even then the motors on those old drives were huge. <Can any of these stories happen to a modern drive? Less likely as smaller platters, less mass and more exotic speed control servos. The big difference is that you would need som really amazing RPM to make a 3.5" plater fracture and fail where a 14" platter has a far higher speed at the perimeter at a lower RPM. Without running the numbers a 14" platter goes transsonic at the perimeter at something like 14,000 RPM however before you get to that speed the forces working on the metal are high enough that it will exceed the tensile strength. Also small imbalances show up with increasing rotational speed and the platter start to develop vibratory waves which if allow to go to destructive extremes make for good stories. I know as I have an operating Morrow (thinkertoys) DISCUS with a 10mb memorex(m101) 8" drive. Allison

'Classic' typewriter?

by kyrrin＠jps.net

Yes, you read correctly. One of the local thrift stores turned up a Xerox 'MemoryWriter 630' for all of $8.00. Since I was in the market for something to fill out forms with, and curious about the MW series in any case, I picked it up (with a grunt -- these are not light!). It's built very robustly inside, and appears to be based heavily on the 8085 chip. The design and layout resemble (no surprise) the Diablo 630 series daisywheel terminals. A good vacuuming and a little oiling later and it works just great. Original manufacture date is around 1984 (based on the date codes I found on the components). No CRT on this one, though I understand that was one option. If anyone happens to have a user's guide, accessories, options, or diskettes for this beast, please let me know.

Some time ago, I had a little Seagate 50MB drive on running on the shelf above a workstation. I knew it had a stiction problem, so I tended to leave it running most of the time. So there I was, minding my own business, as they say, and suddenly there was a very loud BANG. I couldn't see anything amiss, but I shut things down anyway. Then I realised any damage that was going to be done by whatever went bang had presumably already happened. I wasn't going to find much out by staring at a blank screen, so I powered everything up again. All came to life, but the Seagate just reported disk errors. Tried reformatting; no joy. So I took it apart. Every platter had huge circular gouges, and two of the heads were in bits, mostly embedded in the walls of the disk chamber. -- Pete Peter Turnbull Dept. of Computer Science University of York

Artistic Computers (was: Re: Lost Treasures (was: Cray-1))

For direct to ugly... Commodore PET netronics explorer-85 intel mds800 minutman missle computer (lots of ways ugly!) I can think of others but those were pretty ugly on an esthetic basis and a few were ugly from a human factors standpoint (pet chicklet keys). Programming the serial disk computer of the MMC was really nasty. Allison

I believe KISS tends to apply in these cases. In general, I find that I like blockier ones more. I won't get myself started on modern case design, but I will say that I do not find any of the "home computers" by Compaq, Toshiba, Acer, and Sony to be very nice-looking. Of classic computers, the TI 99/4a probably is in that vicinity... >On Sat, 2 May 1998, R.

Auction crap

by aaron＠wfi-inc.com

In case anyone cares, I put another Sun 3/50 and a Sparcstation 1+ on www.haggle.com. The 3/50 is a 12meg flat-top, and the 1+ has 36megs and a 205meg HD. I started them at something like $5 so they'll probably go for just enough to cover packaging tape. The impetus? The space is now being hogged by the System 36 I just dragged in here.... By the way, does anyone want that Sperry IT I got awhile back? It is sitting in the garage looking forlorn. It has that nifty Genoa video card, a memory board, an ethernet card, an unknown size HD, keyboard, optical mouse and pad, complete manual set (system installation guide, Basic user's guide, and MS-DOS user's guide), and original disk set. I haven't had the chance to even power it on yet, so I don't know the operational status (worked when removed). It's heavy (duh), so if someone just wanted the cards/HD/etc, I could disassemble and ship what you wanted and leave the carcass at the local thrift. Oh yeah, I am in the L.A. vicinity, so if someone wanted to pick it up.... Aaron

<A question occurred to me today : Can you have an embedded analogue <computer, and if so, how many op-amps are needed to have one? Yes, and that's very common. None, a low pass filter(RC) performs a function and can be considered analogue. <I was looking at the service manual for my Micropolis 1203 hard disk, and <I read the circuit description of the servo electronics. It's a fairly <complicated array of op-amps, which combine integral and differential <forms of the position error, positioner current, etc. I would claim that <is an embedded analogue computer. Valid claim, also a good example of a fairly complex function. <On the other hand, I think it would be stretching the definition to call <a simple op-amp wired as a voltage follower an analogue computer. Correct. However often the buffer is between some function or follows one so it's part of the analog system. Other analog systems common to computers: cassette IO (low pass filter on output) and complex filter/differentiator edge/peak detectors for input. Some of the acients used PLLs for clock recovery (KANSAS City is one). Analog to digital conversion (quantification). Digtial to analog conversion (filtering) Disk/tape systems have several layers of analog function for data and control. Allison

Compaq laptop dock FS/Trade

by rhblake＠bbtel.com

Ok Compaq laptop owners (you know who you are). I have a near new unit to sell or trade as follows: Compaq 2815 Desktop Expansion Base. Looks a lot like the Prolinea line of desktops with a special lid to slide your laptop machine into a "bay". It has no drives (blanking plates) but has an internal contrller for floppy or hard disk and the empty bays. Has a token ring card now in one of the two ISA slots. Includes ports for VGA, LPT, COM, KB and mouse. Has an A/B switch on the rear that I really have no idea of it's use. This is like brand new but has no manuals. Looking for $100 cash or will consider trades of items such as memory, cdroms, sound cards (especially MCA PS/2 types), etc or a complete Snappy 3/3 Deluxe setup. I will also consider equal value electronics test equipment in trade especially function generators, signal generators, frequency counters, Fluke DMMs, etc. Email me direct please. -------------------------------------------------------------------- Russ Blakeman RB Custom Services / Rt. 1 Box 62E / Harned, KY USA 40144 Phone: (502) 756-1749 Data/Fax:(502) 756-6991 Email: rhblake(a)bbtel.com or rhblake(a)bigfoot.com Website: http://members.tripod.com/~RHBLAKE/ ICQ UIN #1714857 AOL Instant Messenger "RHBLAKEMAN" * Parts/Service/Upgrades and more for MOST Computers* --------------------------------------------------------------------

kaypro<->IBM?

by SUPRDAVE＠aol.com

ive been in communication with a lady that has an old kaypro with a lot of text files on disk she wants to transfer to an IBM for further editing and safekeeping. i presume i need to cable their serial ports up and transfer that way, but exactly how? i need some sort of program to send the files on the kaypro i guess, but have nothing to do it with. if i can do this file transfer, i'll get two working kaypros, a TI word processor from 1985 and some NLQ dot matrix printer shipped to me free. david

Hi All - Just joined the list - looks like a great resource for information. I've been collecting vintage micros for a couple of years now and only recently discovered there were other fools with the same bad habit. Currently I've got about 50 assorted Commodores, half-dozen Apple ]['s, two Kaypros, an Osborne Executive, a TRS-80, a couple of TI-99's, a bunch of Atari, Coleco and other game machines, and the rest of the garage is filled with boxes of tape drives, modems, printers and other peripheral stuff. I'm always interested in trading, so if there's something you need, let me know. I'll go back to lurking now. R. BTW - I've been compiling a chronological list of every computer ever made for a book that I'm working on - big stuff as well as micros. It's a pretty big file, but I'll post it (as a MS Word attachment?) if anyone is interested. -- Robert Arnold Managing Editor The MonkeyPool WebSite Content Development http://www.monkeypool.com Creator and Eminence Grise Warbaby: The WebSite.

This sucks.

by DSEAGRAV＠toad.xkl.com

Well, the KS-10 deal went over like a lead baloon... It seems the HARDWARE to the system has already been packed off to Caterpillar Spares. But the SYSTEM (disk) is still there. THAT is what they were melting down. Not the whole rack, just the RP06 packs that had their data. When I was told the SYSTEM was intact and may be rescueable, we assumed the HARDWARE. When I asked about config, he assumed I meant "What's the monitor built for?" And they don't wanna give me those disks anyway. Basically, I went in and made a fool of myself... Oh well.

Given the number of hybrids around (as we have seen from more recent posts), your system might be better. But AFAIK in the taxonomy used by biologists etc. the list of available classes is different for each phylum, the list of available orders different for each class, etc. But I have a computer that is hybrid analogue/digital (an EAI-1000, I think it's called, which is an analogue computer with a microprocessor doing an embedded control type job to run the system)...

XT Power Supply help... (More Info)

OK... by some act of God, when I try to plug in the HDD alone, it spins up, along with the PSU. Now, when I take EVERYTHING out, that includes drives, cards, etc. and just give the motherboard power, it doesn't spin up at all. Yes, the black pins are in the middle, I know I've got a good connection... could this be the "No power" line thingy? Should a real-XT case work with a clone-XT motherboard? Thanks, Tim D.

Computer Taxonomy

by allisonp＠world.std.com

<However, some of the very simple controllers in, e.g., lawn sprinkler <timers, etc. could possibly be classified as just programmable logic <elements -not really "computers".

Or, rather, an application specific <integrated circuit or ASIC could be specially designed and fabricated to <replace all of this if production quantities are in the many thousands. <Still, no microprocessor chip though. This is not true, many VCRs have version of the NEC ucom75 chips, cmos single chip microprocessor(512b-2kb rom, 128nybbles of ram(max) lots of IO for various purposes). The TI1000 series were used in games and Microwave ovens. Most of the things like lawn spriklers controllers are chips like 8048/9, PIC, or other cheap in volume mask rom single chips micros. The list can go on but true ASICs are expensive to develope and limited in scope. There are an abundance of small very low cost single chip micros that can do tasks like those described. FYI what does seperate most of these from the general taxonomic classes is that the "program" is inaccessable on most of these so altering it is unlikely to impossible. Allison

Lost Treasures (was: Cray-1)

by Marty＠itgonline.com

Funny you should mention the Macquarium. Yesterday on my way home I stopped at a used computer store and found a Mac Plus Macquarium with the original documentation dated 1992 (a mere $60.00 for a butchered Mac... I wouldn't buy one because I don't think it's cute and don't want to encourage this practice). The top of the case had been quite roughly gouged out, a glass tank fitted inside the case. I'd seen this on the web before but thought it was a joke.....

XT Power Supply help... (More Info)

by JRichardson＠softwright.co.uk

Hmm, must be too early... I suddenly remembered a situation like this I had with a motherboard a few years back... check the ISA slots; make sure nobody's stuck a card in there and mangled a few of the pins. This board I was given had the same trouble, and a couple of the pins were shorting out and the system was shutting it down. Nice three-second fix once I'd found the problem!! :) good luck, Jules >

Introduction

by fauradon＠pclink.com

Off Topic posts are the worst, second comes discussions about computers less than ten years old (which eventually fall in the off topic category) Try to locate the List FAQ to find out more (it doesn't list the flame war starters but if you can stick to the guidelines you'll be OK). Then again I'm not in charge of this list either. As a general rule this is a list for the discussion of more than ten year old computer equipment. Use plain text to send messages. Be nice and have fun. >Thanks for the tip. Let me know if there are any other no-no's or flame bait. > Francois ------------------------------------------------------------- Visit the Sanctuary at: http://www.pclink.com/fauradon

Lost Treasures (was: Cray-1)

by peacock＠simconv.com

>Some sick minded person might gut a NeXT cube and use it as >a little stool for flowers at an exhibit of abstract art ;) > In the early S-100 days (1975) the engineering lab I worked in got an early Altair (we needed small cheap computers to embed in environmental monitoring instruments). A few months later we got one of the first IMSAIs. After about 3 minutes of comparing the two, we voted to use IMSAIs and the Altair was relegated to being the doorstop for the lab doors. I assume it wound up in a surplus action some number of years after I left. BTW, the embedded controller we actually used in the instruments was a single board Intel 8080, their evaluation kit board, the precursor to Multibus. We used the IMSAIs to develop and test the code in the lab. Jack Peacock

XT Power Supply help...

by Marty＠itgonline.com

I've never seen an 80W power supply. All original IBM 5150 PC's I worked on had a 63W power supply and the IBM XT's all had a 130W power supply. You mentioned your supply has a 220V selection? If so and you are stateside, make certain it is in the 110V position. If you have a 220V power supply that doesn't have a 110V selection and you're stateside... you're out of luck. I concur with all those previous respondents that this supply of yours is most likely good but loaded down either by excessive loading (more cards/memory/drives than the P/S can service) or a short circuit in one of the add-on boards or drives. Just unload until you find the cause. Marty ______________________________ Reply Separator _________________________________ Subject: Re: XT Power Supply help...

The PC's Soviet?

by photze＠batelco.com.bh

Yep, Apple Records. Actually, it was founded by Paul Macarthney (however you spell it) and John Lenon, the Beatles. Their idea was to have people coming in, and doing what they wanted, getting profits for their records, and not having to go beg the brass at some corporation. They lost more and more money, into the 80's, when they were "eaten up" by Capitol records. The Beatles CD's available now from capitol still feature the Apple logo (not Apple Computer), and the CD's also have it. Ciao, Tim D.

I've got an old pre-XT machine somewhere with the 63W supply, I seem to remember it wouldn't even power one 10MB drive with motherboard and a single floppy drive in place... I can't remember why on earth I even tried it though, I don't think the pre-XT machines (what was their proper title btw?) would even run a hard drive... cheers Jules

Kaypro 2 update

by ds_spenc＠alcor.concordia.ca

I finally had enough time today to go to Canadian Tire and pick up a set of allen wrenches, so I finally pulled the disk drives out of my ailing Kaypro 2. I moved the resistor pack to what was formerly drive A, and swapped the jumper blocks, put everything back together... and it worked! The Kaypro 2 booted up WordStar with absolutely no problems. Now drive B (formerly drive A) can't be accessed. It gets a "Bdos Err On B: Bad Sector" on known good disks. So it's definitely the drive that's bad. Mechanically the drive seems sound, so I guess I have to assume that there's something wrong with the electronics. I haven't done a side-by-side comparison with a working Tandon drive to see if there's any obvious differences, though. Doug Spence ds_spenc(a)alcor.concordia.ca

XT Power Supply help...

In a message dated 98-04-29 09:23:09 EDT, you write: << Hi. After getting a new M Board for my XT and a load of cards, I found that my Power Supply's now completely dead. So, where to I start?

Thanks, >> heres a quick and dirty way to test one: if you have a hard drive, plug that into one of the power connectors, then hit the switch. that will let you know if its working or not. this test will work, as i use an xt supply just to run a scsi drive for my mac when i bring it out for testing once in a while. if not working, i have several extra xt supplies i need to get rid of. message me privately if interested. david

Kickstart and Workbench 1.2 for Amiga 1000

The symptoms you describe could also mean that your disk drive is out of alignment. Early Amiga OSes were floppy-bound and did a lot of gronking, which wore out a lot of drives. - John Jefferson Computer Museum <http://www.threedee.com/jcm>

Tony Cole's Cray-1

It is some years since I looked at the Cray 1 in the Deutches Museum in Muenchen (Munich), but I distinctly recall seeing lots of 10xxx chips in it. I remember I had just been given a board from the CPU of a Cyber two-hunderd-and-something (?) that had been thrown out by Muenchen Technical University a few months earlier, and this board has lots of 100xxx chips on it.

Suicidal HDD (OT mystery)

by maxeskin＠hotmail.com

I posted this a few weeks back, but noone answered, so I'll ask it again. There is a certain Macintosh 5400/180 at my school whose hard drive crashed about a month and a half ago. When it tried to start, it wouldn't really seek, just made a ticking noise and the LED would flash. So, we took it out, ordered another one. A few days later, it died the same death. So now we have another one. My ethics don't allow me to just put in a hard drive knowing it will be destroyed. What should I do? One hint is that the Macintosh is in a soundproof booth, and is powered from the booth, which is plugged in. But, the mac is plugged in via a "surge protector". Ideas? Could it be bad power? Any way to check? ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

XT Power Supply help...

by JRichardson＠softwright.co.uk

>> Hi. After getting a new M Board for my XT and a load of cards, I found >>that >> my Power Supply's now completely dead. So, where to I start? No fan, >>moves >> a turn or two, I know that the power connections good. Could you simply be overloading it? Seem to remember original IBM XT supplies do this when there's too much load on the system - does the supply seem to work without anything connected to it? The fan should at least spin then... It's equally likely that one of the cards you've got, or the motherboard itself is faulty in some way and is causing the supply to shut down. If you've got a voltmeter try checking the output voltages. Final possibility: did XT supplies have a "power good" reference line that the motherboard tied to +12V to signal that everything was Ok? Can't remember if this was only AT systems that provided this. If they did it may be that your new board doesn't provide it but the power supply expects it to (wait for someone else's words of wisdom I guess, been a while since I've fiddled with these things - if that is the cause though you should be able to simply tie the line to +12V and then everything should work... :) cheers Jules > >
