I suppose that you only need to find the cable that's broken and just jump that one, rather than replacing the whole lot. You may even be able to find the break, scratch off whatever coating is around the metal conductor, and solder across the break (Ok, so it never worked with Sinclair keyboard ribbons, but it might be possible here :) cheers Jules

Tektronix XD88 Unix box - help/info needed

by JRichardson＠softwright.co.uk

Hi all, I was given a Tektronix XD88/10 machine a few years ago that has sadly been sitting around gathering dust in the hope that I'd be able to find sufficient info/parts to fix it at some point - maybe someone on this list can help... When I got the machine I just had the main unit, and (amazingly, seeing how only a few of these seem to ever have been built) got hold of a keyboard for it. I haven't got the original monitor, but a Sun 16" display seems to work well enough. The disk was on its way out when I got hold of the machine, and from what I remember wouldn't even boot to single user mode last time I tried it. It's a 300MB Imprimis (Seagate) SCSI-1, so finding an exact or similar replacement shouldn't be too much trouble. The problem is the OS software - I don't have the tapes, and Tektronix stopped supporting the XD88's a few years ago (I heard from one guy in Australia who got an XD88 from a sale without OS, and Tektronix Aus. gave him the tapes for free which was rather nice - they took the line that they should be part of the machine anyway!) Second problem is mouse - the keyboard has a 9-pin *female* port on it for a mouse - anyone know pin-outs, what protocol was needed etc? Other than those two minor details, it works fine :) When I first got it it did boot to some sort of semi-working state; I seem to remember that the ethernet was working on it (I never tried the tape drive, I have a spare in case the one in it is broken though) Thanks for any help though, about time I got this thing going again!!! (Could still be a useful machine actually, it's got 16MB of main memory on it and 2MB for graphics memory) cheers, Jules

Early computer serial numbers??

by archive＠navix.net

Greets: Here's a question for you all: how does early serial numbers on classic machines effect their relative value to collectors. Here's an instance: I recently acquired five (5) old TRS-80 Model III computers. They are numbered in the following way: 0000365 0000474 0000475 0000477 0000510 Yeh, and two, almost three are numbered in succession... how often does that happen. Plus, those particular machines came from two different states, and the successive machines were also split up by 900 miles!! How often does that happen? Anyway, for a TRS-80 collector, or classic computer collectors in general... how does these early numbers effect their value to potential collectors of these machines. I've heard of someone (I think) that had a very early numbered CoCo (less than 10?), but haven't heard much else. Any more of you have stories like this that I mentioned above?

Serial Eprom?

by jpero＠cgo.wave.ca

Hi guys! I have a need to burn new versions for a Always IN-2K scsi card using Xlinx chipset. Currently aspi driver is ingoring the card because the serial eprom containing firmware is old. I have new verions sitting on my HD along with new bios for the 27C256 chip. If you have one chip to sell and have equipment to burn that serial chip, that would be great! I can supply the 27C256-200ns or if you have one rated at 150ns for a price, burn it also. The serial Eprom is: AMD, am1736, DC, 031YEWH (date code?) The bios is 27C256 at 150ns. Thanks! This card also is nearing 10 years so there! Jason D. email: jpero(a)cgo.wave.ca Pero, Jason D.

A certain TI-85 (which I will try to fix, but is not mine) has a strange problem. The display does not display a strip of graphics. Everything else is fine, but about 20 rows just don't work. They DO work sometimes, but are then distorted. The LCD is connected to the board with a ridiculously long ribbon connector, folded several times, made out of thin plastic.

If you have a good stationary supplier nearby, the stuff to ask for is "endorsing ink" which is what's used to re-ink endorsing-stamp (rubber-stamp) pads. Or use WD-40 to extract whatever life is left in the original, if it's dried up rather than exhausted. But go easy, don't add too much, and let it soak in for a while. > Also, the stamping has impressed the numbers into the rubber platen. How > do I get rid of that? When I ran litho printing presses (in a former life) we used a solvent called MEK (methyl ethyl ketone) to undo "blanket smashes" -- dents in the rubber offset blanket caused by crumpled paper under high pressure. It's also used to give the blanket an occasional extra-good clean. MEK is also used in the plastics industry as a solvent and to glue PVC and ABS. It shouldn't be too hard to find. Caution: it's very inflammable, it dissolves or at least attacks several types of plastic, removes ink as soon as you look at it, and also removes the natural oils from your skin, so don't wash you hands in it :-) -- Pete Peter Turnbull Dept. of Computer Science University of York

More on setting-up Sun3 from tape

FWIW: Data General One Laptop spotted for sale

by Marty＠itgonline.com

I paid $5.00 for my Data General One. It's a piece of junk. The screen is IMPOSSIBLE to read, just as Data General boasts about it (go figure this for something to be proud of) at their web site. It is a large and heavy laptop and from a collector standpoint, in my opinion, isn't worth persuing unless you can get it on the cheap $15.00 to $25.00 maximum as a curiosity. An 8086/8088 system by any other name is an 8086/8088 system. $500.00 is a joke. Dream on.

According to DG's website, it was the "first truly portable" PC and they made 43,000 of them: http://www.dg.com/about/html/dg-one.html I don't know what a reasonable offer would be, but it's apparently more than the $15 I offered :-) GRiD's clamshell-style Compass laptop preceded the DG/One by a couple of years (and the GRiD is *much* cooler, IMHO).

Mac II problem

by rexstout＠ptld.uswest.net

Here's the message I just sent to ClassicMacs mailing list, I'm too lazy to type it all again ;-) ============================= Just picked up a Mac II 5/80/two 800k FD's for $15(including a datatronics keyboard and an Apple mouse), with an ethernet card that everyone seemedd to think was a second video card... They said whenever they plugged a monitor into it, the computer shutdown. I hope it hasn't been destroyed... Anyways, it came with System 6.0.5, Word 4.0 and Illustrator 88(and tons of documents for both programs), all of which have already been deleted. Problem is that I'm having trouble getting System 7.0 to run. At first I couldn't get it to boot at all from the disk tools disk, then I finally installed it onto one of the three partitions and deleted the Sys6 system folder. Then it still woudn't boot. I took out the ethernet card and my PC Drive card(which I think may be bad). Now it tries two or three times minimum to boot from the hard drive, and usually refuses to boot from the floppy(although that may be fixed now, I'm not sure). The Apple HD SC Setup on the Disk Tools disk did not see the disk, so I went back to my PowerMac which had a copy of a hacked HD SC Setup I had downloaded. Back to the II, where the disk refused to boot. OK, I finally got it to boot from the HD, then I opened the floppy, and then the system folder. Finally the normal System Folder icon is back and it boots again. I launch the hacked HD SC Setup and it sees a disk at SCSI ID 6(I haven't changed that yet, I need to take the HD out and find the info on it), but it can't reformat. It says it can't prepare the disk for initialization, no particular reason is given... Current config right now is 5/80 with the two 800k drives, and the Radius Pivot interface. Any ideas? I'm stumped. ============================= -------------------------------------------------------------- | http://members.tripod.com/~jrollins/index.html - Computers | | http://www.geocities.com/Area51/Lair/1681/ - Star Trek | | orham(a)qth.net list admin call sign coming soon... | --------------------------------------------------------------

HP Win 3.1 -- off topic, but need help

by engine＠chac.org

Yesterday I did the Silicon Valley Elderhostel comp. hist. lecture, and in the Q&A afterwards, a woman from one of the gold rush ~ghost towns in the Sierra said that her school had been given two HP Vectra 486's, but with no OS's. HP has been forced to follow MS' ultimatum (who but MS could or would step on HP?) and can only supply her with Win95, which these boxes don't have the horsepower for, on CD, but.... no CD drives either. She badly needs HP Vectra OEM Windows 3.1(1) on 3.5" floppies, and HP's response to her is basically "We're only allowed to tell you that that never existed." Can anybody help with a copy?

CMOS Battery for PC/AT

by djenner＠halcyon.com

I picked up an original PC/AT that has a dead lithium battery for the CMOS bios parameter storage. The battery says it's 6.8 volts. It's the kind that is a 1/2x1x2 inch pack with a six-inch lead. I've tried several places to find a replacement, but either a store doesn't have it, or, if they have one, the voltage is not exactly 6.8 volts. So, what's the acceptable voltage range, especially on the low end? And any good sources? Thanks, Dave

DING DING! Back to your corners... WAS: Re: Irreverence to irrelevance

by lfb107＠psu.edu

I think we all need to take a step back, grab a few drinks, and try and look at what's going on here. So far, everyone has had some valid points. If we interpret the FAQ literally than perhaps Sam is right. I would tend to believe, however, that Bill Whitson's original idea was to have "liberal" restrictions on the group so as to perpetuate discussion of "classic" computers. Not all posts have adhered to the exact words of the FAQ. Some examples might be posts on logic probes or on "orphaned" machines that aren't necessarily 10 years old. The idea behind these posts is that it might be something that interests people who like to talk about classic computers or that this mailing list might actually be the best place to get info on that topic. There are noted exceptions of course, but I think that what would be best would be to ignore these posts and just delete them as was earlier suggested. I guess the main thing I'm trying to say is that the FAQ should'nt be treated as gospel but as *general* guidelines that should (normally) be adhered to. This means that instead of launching inquistions against people who may post off topic, a "Hey, please try and stay on topic for now on, but, yeah, I don't like AIWA CD players either" would be nice. There really is no need to attack poeple either. We all have our "allegiences" and we've all probably have had some kind of altercation with Sam in the past but I really think that we shouldn't take all this THAT seriously! Sam has called me an ass recently too. SO WHAT? I sent an e-mail back to him and called him an asshole too. CASE CLOSED. We're ALL assholes to some degree but when it comes down to it, if I need help putting an Apple II back together (something I know NOTHING about) than Sam is here to help. So... on that note. I am in need of some old removable SyQuest disks for an SQ555 drive. (the 44mb variety) Anybody know where I might find some? The local 'puter store still sells them for $40 a pop! Thanks, Les lfb107(a)psu.edu

Russian PDP-11 info source

by healyzh＠ix.netcom.com

In case anyone is interested I found an odd source of a little info on a Russian PDP-11 the BK0010. The February issue (107) of Amiga Format, which should currently be available in the US, has a section on Emulators, and they talk about the BK0010. In my area both Barnes and Nobles, and Borders books carry the magazine, with Borders carrying the version with CD coverdisks for ~$15, and B&N carrying the Floppy coverdisk version for ~$10.50. The emulator wouldn't be on the floppies, but it MIGHT be on the CD, I don't know, I've not had time to look at my CD. There is an emulator available, but the minimum system requirements are a 68020 WorkBench 2, and 1Mb RAM. A 40Mhz 68030 is recommended to get full speed, and apparently a 68060 is to fast. In all it's only about 8 paragraphs, but it might be of interest to some of the PDP-11 enthusiasts on the list. I've no idea if the emulator is available for any other machines, but it might run in the Amiga emulator if you have a fast enough machine to run that on. Zane | Zane H.

What's an RA90?

HP Win 3.1 -- off topic, but need help

Sorry, but this is just a thought... if HP could give Win 95 LICENCES, and you could find a 3.5" copy of Windows 95 (and the HP's have 8MB RAM), you could run Windows 95 fine.

drive info needed

by jpero＠cgo.wave.ca

All right, guys, After conferring with Allison, we found out thus: > > <Could you check the grounds on one row of IDE pins it's very easily > <visiable on solder side if it's more than 4 pins in middle, it's XT > <ide interface otherwise it's true AT IDE and yeah you can slave this > > All the even pins on the drive are ground, it has the 42c22 chip. I > suspect 8bit (xt) IDE. If mueller is to be believed it's 8bit IDE. This is right, that 93028-A is original pack with ATA logic board but somehow was blown, (Commonly happens), so someone found a good XTA interface logic board from dud 93028-X hd and installed that to this good pack. I suggest you cross out that -A and scribble on a -X? I had so many logic boards of all kinds of Tandon make and WD make, packs were bad too and that shows how high failure rate was with these design. Worst design indeed. Even the same period of time an ST1102A had 150K MTBF compared to those drives with 30K. > <Also, Allison, check that 8 bit card, sometimes it's rare to > <find one > <that will support AT IDE drive on that 8 bit card. > > I have an accutrack isa-8(xt) adaptor for standard ATA IDE it has a > miniscribe 8051A hooked to it. (!!) I have Miniscribe 8051A too. Thermal problem, stays dead but spinning and making funny noise for few minutes then power cycle it, comes up fine. This is only oddball hd I know of that used moving magnet with the coil fixed to the hd case. Snip. > They exist. IDE drives plugged into XTs are no big thing and JAMCO or > JDR has a board for that.

I wish I could learn to make a simple adapter for both 16bit and 8 bit wide, using an ATA drive. So far, I was bit frustrated with some info I found on the net. Did you got good one I that I could understand how to design one? For starter, making a GOOD complete buffered type card with IORDY selectable ATA card for ISA bus? Far as I can understand, a choice of binary setup for first address 10 bits long selects the IDE address beyond that zip. Many cheapo cards have partial buffering which is bad for the IDE chipset. Is this assumption correct? > > I can use an 8bit IDE drive for a CPM system. Then use this that WD 93028-X for this CPM system? > > Allison Jason D. email: jpero(a)cgo.wave.ca Pero, Jason D.

capability. The drive that you have - unless someone has swapped logic <cards - cannot be expected to work with the 8 bit card. Whatevery you do wisper that... it's running with the 8bit ide adaptor in my xt. There is no reson to suspect the card was ever swapped. Allison

Mac II

by rexstout＠ptld.uswest.net

Just picked up a Mac II for $15, looks like 5MB of RAM or so, 68020 & 68881 FPU, two 800k floppies, an 80MB hard drive with three partitions, and an ethernet card. I swapped out the old Mac II video card since it didn't work with my monitor(64k Mac II video cards from Apple don't do very much) and put my Radius Pivot monitor/card in it, and it works OK now. It's running System 6, so I'll have to upgrade to at least 7.0(i think I have it on 800k around here somewhere) or maybe network it and install 7.1... Also got two "black boxes" for free, one is an automatic RS-232 switcher, and the other appears to be a RAM buffer for RS-232. More info after I figure out exactly what they are... Tonight is going to be busy(upgrading with spare parts I have, looking for info, etc...)! -------------------------------------------------------------- | http://members.tripod.com/~jrollins/index.html - Computers | | http://www.geocities.com/Area51/Lair/1681/ - Star Trek | | orham(a)qth.net list admin call sign coming soon... | --------------------------------------------------------------

More on setting-up Sun3 from tape

by rcini＠email.msn.com

Well, I resolved the tape drive access problem on my Sun3 workstation. Although no other device on the SCSI chain is terminated, the Sun3 does not like the DD50 passive terminator that I have on the end of the chain; it will only access the drives on the chain without it. Anyway, I can now load the tape boot image and start the mini-kernel. Really, the question that I have today is related to the "edlabel" partitioning program. Although the following results from using edlabel, the question is more about disk partitioning in Unix. The drive is a 330mb SCSI hard drive with the following geometry: 512 bytes/sect, 32 sect/trk, 15 trk/cyl, 1254 cyl (as reported; maybe should be 1408 cyls?). Running edlabel reports the following: start c/t/s blks c/t/s type a(root) 0 0/0/0 29297 61/00/17 4.2BSD /* 15mb boot b(swap) 0 0/0/0 0 0/0/0 swap /* swap (would like this to be ~10mb) c(disk) 0 0/0/0 601920 1254/0/0 unused /* disk d(user) 0 0/0/0 0 0/0/0 unused /* user I can create the root partition (and write it to the disk as shown above) with no problem, but I cannot create the swap and user partitions. I get the following error: "ioctl DIOCWDINFO: invalid argument". This is the first Unix drive that I'm setting-up in a non-automated fashion; can anyone give me the benefits of their experience in doing this?? Thanks!

drive info needed

I have a WD93028A disk I know the geometry but the interface is apparently IDE. It's currently attached to a 8bit ISA card (also from WDC) and I'm curious about it. What I need to know is what flavor of IDE it is (it may be 8bit) and its pinouts. Allison

System/34 again

by maxeskin＠hotmail.com

OK, I moved the System into a room where there is light and power. There are no 220V plugs, though. So, I have 2 choices: a)Step-up transformer - how much would 110-220 1700 watts min. cost? b)Using a bunch of PC power supplies to power the DC components. My first problem is how I trick a PC/AT power supply to stay on when it's not hooked up to anything. Do I need to short something? Next is the problem of pinouts on the 34. There is ground and +5v labelled clearly. THere is also a circuit board with lots of screw terminals.

HP 82143A Peripheral Printer

by ds_spenc＠alcor.concordia.ca

I picked up an "HP 82143A Peripheral Printer" a little while ago. It physically resembles the "HP 82162A Printer/Plotter" that is pictured, attached to an HP-75, in a little book entitled "Computer in Your Pocket" which reviews several early pocket and notebook computers. Will the 82143A (the one I have) plug into an HP-75? Will it work with anything else? What kind of battery does it take? Power connector? Pinout of the 12-pin connector? The printer still has a small roll of paper in it (about 2.25" wide) and I wouldn't mind finding out if the thing still works. I got it at a Salvation Army store, and there was no sign of whatever it had been attached to. Doug Spence ds_spenc(a)alcor.concordia.ca

Silicon Graphics Power Series machines available (Chicago)

by eric＠fudge.uchicago.edu

My department is getting ready to scrap two Silicon Graphics Power Series computers. They are both quite dead (parts from the one were used to keep the other going until there were no more reliable CPU boards left) and have been stripped of some parts, but it may be possible to bring them back to life by some magic, or at least to get some use out of the 19" racks and power supplies. If you have any interest in these, please let me know as soon as possible before they are thrown away. They are large and heavy and you will have to pick them up from the campus of the University of Chicago. Eric

Tuning 8" floppies

by dwollmann＠ibmhelp.com

I have a MicroTech ReformaTTer unit with two 8" NEC floppies attached to a PC with the MicroTech FDC. Both drives seemed to be in need of a tune-up (head alignment, in particular) when I installed the unit, and now (this is four yrs. later) I can only read diskettes with one drive, the other just gives me "sector not found" errors. Is it practical for me (me = board swapper) to try to align the heads on these drives manually by trial and error? Is there still a source for the disk required to do it the right way? I have access to a scope if I need one. -- David Wollmann dwollmann(a)ibmhelp.com

GPIB + disk drives

by rigdonj＠intellistar.net

Doug, I saw Tony's reply and responded to it before seeing this one. I thought you had an HP drive but since it's a GRID drive I can't say what kind of format or command set it uses.

"First" key system?

by kyrrin＠jps.net

Sam Ismail typed out... >I have an AT&T Horizon phone system (circa late 70s) which is significant >in the history of telephone systems as it was the first "key" system. It <reaminder snipped> Sam, speaking as an ex-telco person, I can say with confidence that the Horizon was far from being the first "key" system. That honor goes to the original electromechanical 1A system, which was introduced in the late 50's/early 60's. During the early-to-mid 60's, the 1A1 was introduced. It had several improvements over the 1A, mainly in reduced size, weight, and complexity. In the later 60's, the venerable 1A2 key system components were introduced. They endured well into the early 90's, and are still in use in various incarnations to this day (I have a 1A2 system here in the house). The Horizon system fits neatly into the category of 'hybrid' systems. It could, dependent on programming, become either an electronic key system or a small PABX, incorporating the best features of both. Thus endeth key system history 101. We now return to normal topical stuff. ;-) BTW, if you ever want to look for a good home for that Horizon... ;-) -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Sysop, The Dragon's Cave BBS (Fidonet 1:343/272) (Hamateur: WD6EOS) (E-mail: kyrrin(a)jps.net) "Our science can only describe an object, event, or living thing in our own human terms.

CMOS Battery for PC/AT

by Marty＠itgonline.com

Typically the CMOS battery voltage runs from 3.6V to 6.8, either should do okay (in my experience). Try Fedco @ 1-800-542-9761 or Battery Biz @ 1-800-848-6782.

And it did move back to its usual position. Well, if the ones that don't boot do move the heads, and the light comes on, sounds like the machine can "see" them and make them respond, but just can't read the data. It's still possible they're faulty, but if they're all single-sided, my guess is that one pair is 40-track and the other is 80-track. However, if this were the case, I'd expect that the boot would go partway (the drive would probably read track 0 OK, but not any other). > > Usually there's a set of jumpers, or sometimes a small DIL switch pack, > I'm afraid it's not that easy.

Drive crash

Kaypro: 81-146A vs. 81-232

by ds_spenc＠alcor.concordia.ca

I finally opened up my Kaypros today to see if I could get the '2' working. The II and the 2 seem to be almost identical inside, with two notable differences: One of the ROMs has a different number on it, and my Kaypro II has some wires soldered between pins on one of its chips. The Kaypro II has a chip with a sticker marked "81-146A", with the "A" stamped on in read ink. The Kaypro 2 has a chip with "81-232" on it, in the same location. What are the differences? The chips at position U87 on both motherboards are marked DM74LS390N, but the one in the Kaypro II has been messed with. It's a 16-pin chip, and pin 1 has been bent upward and a wire soldered onto it, which leads to pin 6. Pin 9 is missing. Pins 12 and 15 are attached with a wire. Is this normal for a Kaypro II, or has someone made a modification? Anyway, I managed to make a copy of the WordStar disk that came in the drive of the II today, using my Amiga 1000, A1060 SideCar, A1020 5.25" floppy drive, and TeleDisk. So now I have a disk that boots reliably instead of 1 out of every 5-10 times. That meant that I now know there's something wrong with the Kaypro 2, because it won't boot at all with the new disk. Before, it may have just been a borderline disk that was causing the problem. So (tell me if this was a bad/dangerous thing to do) I opened both machines up and attached them to each others' disk drives. They were plugged into a power bar, so I powered them up simultaneously with that. The Kaypro 2 boot up with no problems, using the II's drives, and the II was incapable of booting using the 2's drives, so I've got the problem located to drive A of the Kaypro 2 now. And BTW, both the II and the 2 have full-height drives. Both keyboards have missing keys (including broken plungers). Will this be easy to fix? I'm thinking of fixing the 2, and using the II for parts, simply because I like the colour of the 2's green phosphor monitor better (and some other minor things). :) Is one model more rare than the other? IOW, does one warrant saving more than the other? If not, I'll go with my feeling and fix the 2 with parts from the II. Doug Spence ds_spenc(a)alcor.concordia.ca

Just wondering

by peacock＠simconv.com

>I remember reading a Byte article that told how to build a computer that >used a variant of the Z80 by Hatichi (I think that's how you spell it). >The computer was about the size of a lunch box. Apparently I have misplaced >that particular issue an was wondering if any one had it and was willing to >tell me where I could find the printed circuit board and the boot disks or at >least send me the art work and the parts list for this particular beast. The part is a Hitachi 64180, an improved Z80. Zilog also makes a similar part, the Z180. I recall the article, It was from Ciarcia's Circuit Cellar series. I think his company sold the kits, MicroMint (?). The 64180 was a nice improvement, made it much easier to add DRAM to a Z80. The drawbacks were the odd pin spacing on the DIP (70 mil centers instead of 100) and a less than perfect fit to the newer Zilog peripherals like the SCC or CIO. I believe the Zilog version fixed up the signal problems with cascading interrupts and also added one more address line (to a full 1MB). Aside from the faster clock rates and built-in peripherals, the nicest feature of the '180s was the memory management. The CPU had an integrated memory management unit to extend the 64K address of a regular Z80 out to either 512K or 1M, using three bank-switched regions. I still have a homemade CP/M system using the 64180, 256K DRAM, 16KB EPROM, two CIOs, one SCC, a National 58167 clock calendar, and a WD MFM hard/floppy controller card. It runs CP/M V3 and used the MMU to access all of the 256K RAM. I built it before Ciarcia came out with his board, chances are I would have used his for the project instead of doing a custom card. I keep it running for sentimental value, it was the first card I ever designed (and got working) with dynamic RAMs. Jack Peacock

Epson "Homewriter" cart needed

by rhblake＠bbtel.com

Need a cartridge based interface for an Epson "Homewriter 10" for Commodore - or any other machine they made a cartridge for the printer for. I have the manual for the Commie cart but no cartridge so the printer is kaput. It's essentially an LX-86 with a modification to make it accept cartridges for an interface in place of the serial or parallel inputs. The Centronics connector isn't even there although the board could accept it but one of the main chips is removed to accept a plug in connector for the "CATI" board. If anyone has this or even a good logic board for an LX-86 (maybe you have a printer with a dead printhead?) let me know and we'll work something out. I hate to have the thing lying around if it's not useable. -------------------------------------------------------------------- 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/ * Parts/Service/Upgrades and more for MOST Computers* --------------------------------------------------------------------

HP cards-anyone?

by rhblake＠bbtel.com

Ok, here's a group of cards made by Hewlett Packard that appear to be of a mini computer style.... The first three have the white extractor tabs on two corners (much like an HP 1000's cards do) and are 7.5" by 17" and have female header connectors on the bottom 17" edge. Here's each card: 1) p/n 07980-66503 and has three bios looking socketed chips in the upper left corner. These are numbered 88780-12122, -12222, -12322 and there's a crystal for 20mhz on board. My guess is it's a processor board? 2) p/n 07980-66534 and has a quick lock type ribbon cable socket on the top/left, two bios looking chips numbered 88780-12423 and-12523. this has a flat coin type battery next to the ribbon connector, a Motorola MC68000 and 12 mhz crystal below that. Isn't the 68000 part of the Mac computers? I have no guess on this one other than maybe an processor or emulator card. 3) p/n 07980-66531 and has two ribbon quick locks. One is the same as the last card but behind a steel shield plate. The other is similar to the one used on older floppy controllers. This one also only has two bottom connectors rather than three like the other two. The fourth appears to be an SCSI card. It's irregular in shape and has two 50 pin Centronics females as well as two 50 pin quick lock ribbon connectors, one next to the Cent's and one on the opposite side. There's a bios type chip with a label reading 88780-12618/U51 SCSI 6.62 and a strange type brown two pin poweer connector. It appears to be mounted by screws, not cage/slide mounted. It measures 11" x 6.25" and has a cutout of roughly 3.5 x 4.5 inches near the two prong brown power type connector. Ok...you people know more about the big hardware than me. It's been 5 years since I've even seen an HP 1000 mini (from when I used an ESTS station in the AF to test missiles) and it's all a blur. Anyone know what these are, what they're from, and a possible new home for them? I hate to throw away the heavy hardware since I know it's costly and in some cases scarce. If someone wants to make me an offer for the four I'm sure I'd take it. Remember, these look like they're good and are untested. Let's face it though, anytime you can get something HP without paying HP's price you're doing good. I'd especially take anything PC parts wise in trade for these if someone has something good they can spare. Make me an offer and we'll go from there. They WILL go to the dump at the end of March though. They weigh probably 5-6 lbs for all four, very light. -------------------------------------------------------------------- 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/ * Parts/Service/Upgrades and more for MOST Computers* --------------------------------------------------------------------

Mystery Board

by ds_spenc＠alcor.concordia.ca

I picked up a board at a Hamfest last summer, and I still don't know what the heck it is. It may not even be computer related - might come from a photocopier or something. :) The board measures about 7.75" in length, and a little over 3" high. Its slot connector has 72 pins, measuring a bit more than 3.5" in length. It LOOKS like it could be RAM, but it's not like anything I've seen elsewhere. There are 16 long "plates" of what seems to be some kind of ceramic material, each with four chips embedded in them, two to each side. The "plates" measure over 2" in length, are notched at one end, and are marked "125B", "886-2". The chips that are embedded in the plates are marked "-607-2", with varying numbers beneath (e.g. "01386 34", "04836 77"). They appear to have 30 pins each, with 10 pins on each 'long' side and 5 pins at each end. All pins come out the bottom of the chips rather than the sides as on DIPs. There are some other chips on the board, three of which (20-pin) are labeled: AM2966PC WP90101L1 8546DMP There are seven 16-pin chips labeled: WE 63S 1 11085 74 And another 16-pin chip labeled: WE 63S 1 12685 77 There is a yellow bar-code sticker on one end of the board which reads "860C03900901". There's a stamp in the middle reading "ATP221". On the back side of the board is "844292540 AM 2 CM192B". I've probably gone overboard with the discription, but I don't know what info is relevant to identifying this thing. The guy I bought it from clearly didn't know what he was selling (but I asked anyway). I bought it with a bunch of old PC cards filled with old RAM chips I may need someday.

Wargames

by peacock＠simconv.com

>I just saw Wargames; what an excellent movie! I encourage everyone who >hasn't seen it already to see it. > >I ask this question when seeing any technology-based movie; >how much of the technology is actually possible? Who was Professor >Falken in the movie based upon? Can a JOSHUA be built? > Look for another movie sometime, "Dr. Strangelove". The crazed nuclear scientist character in most all movies is based on Dr. Edward Teller, father of the US H-bomb (Sakharov produced the soviet H-bomb at the same time) and an influential advisor to Eisenhower. Teller is also the guy who convinced Reagan to go ahead with the "Star Wars" missle defense program (and if you think that "Star Wars" was a stupid idea that was cancelled, guess again, it is alive and well, just goes by other names these days). As for the rest of the movie, it was pure Hollywood. Secure facilities don't have unsecured phone line, and especially no incoming phone lines. BTW, the kid's computer was an IMSAI S-100, and the graphics (if I recall correctly) were generated by Godbout S-100 systems. Jack Peacock

MacSnap SCSI, MacSnap memory

by ds_spenc＠alcor.concordia.ca

I've got a Mac 512K that came with two MacSnap devices installed in it. The MacSnap SCSI adapter plugs into the Mac's ROM sockets, and provides a 25-pin SCSI connector out the back of the Mac. The Mac seems to pay no attention to my Zip drive when it is attached to this connector, though, so I guess that it needs some kind of driver? Does anyone have this software? Also, the machine came with 512K on a MacSnap memory board. It looks like there's enough space for 1.5MB on the board. I had to remove the board to get the Mac to boot, however. Even the "Sad Mac" image was garbled with this thing in place. I think it is because two of the connectors are cracked. The MacSnap memory board actually snaps onto the top of existing chips on the motherboard, because there is no "normal" means of expanding the Mac 512K. Does anyone know if the 16-pin "snaps" are standard parts (i.e. AVAILABLE)? These are parts that fit over 16-pin DIPs, with metal contacts that push against the legs of the chips. What would be the proper name for these parts? There are four 20-pin "snaps" and two 16-pin "snaps" on the underside of the memory board, but it is only the 16-pin parts that are cracked.

Z-80 Video Pak

by ds_spenc＠alcor.concordia.ca

I think I've asked this before, but it might be a different crowd out there now. Does anyone know the specs of the power supply needed to power the Z-80 Video Pak from Data 20 Corporation? This is a cartridge for the Commodore 64 that is supposed to allow the 64 to run CP/M, and gives it an 80-column text mode. Does anyone have a manual for this cartridge? The only info I have on it are from the text on the box, and from inspecting the cart itself. Doug Spence ds_spenc(a)alcor.concordia.ca

Fairchild FST-2?

by COAKLEY＠AC.GRIN.EDU

> After hearing about some of the cool things you folks find at thrift > stores, I decided to hit a couple today. I was pretty disappointed in the > slim pickings, but I found a couple of interesting but useless items: If you're referring in part to the HP-41 I mentioned last night, I went back today and it was gone. Sob. If any of you are in Oregon, though, it's probably worth your while to go to the Goodwill on Coburg Rd in Eugene. Frequently. Today, they had a Heathkit H19, a Kaypro 4, an AT&T 6300 PC, a couple of Laser 128s, a couple of CoCo 2s, stacks of C= stuff, a Sperry luggable XT, something that said Vector Graphics on it, and lots more. All priced at under $10, and today was 40% off day. That list only contains stuff that was still there when I left - I'm driving across the country tomorrow morning, so I'm under some space constraints. Normally, I'd offer to pick things up for people and ship them off, but like I said, I'm driving back to Iowa tomorrow. Eugene/Portland people on the list? -- Ben Coakley http://www.math.grin.edu/~coakley coakley(a)ac.grin.edu Station Manager, KDIC 88.5 FM CBEL: Xavier OH Wow, this is global. -Mtn Goats
