electronics/computer surplus in Virginia?

by netsurfer_x1＠hotmail.com

I don't know of any dedicated electronics/cpmputer surpluse tores in that area. However, I suggest to you that if you ever run across any CHKD (Children's Hospital of the King's Daughters) Thrift stores to go there. Why, you ask? Very simple, I've been there on many occasions and see lots of computers (most are PC) but I had to pass on an Atari 520ST and (just yesterday!) had to pass on an Amiga 2000 (the whole setup cost less than $30!) just bacuse I live on ship, and have no room for this stuff. ____________________________________________________________ David Vohs, Digital Archaeologist & Computer Historian.

Self-combusting Speccy

by optimus＠canit.se

So I find this nice little program called "Toot", which "toots" Spectrum snapshots into the earphone socket of said machine. What happens when I plug the machine in? A hideous smell, that's what. Now I'm back at square one. No working Speccy. All I get is a black screen. When fine- tuning the receiver, the border is sometimes visible. Is there something irreplacable, like the ULA, which has broken, or is it the CPU (I've got plenty of those) or just some discrete component? -- En ligne avec Thor 2.6a.

SGI Indigo keyboard and mouse wanted!

by marino13＠btinternet.com

Hi all... Have been trying to find these for ages now but may be worth a re-ask! I have an old SGI Indigo Personal Iris minus keyboard and mouse. Does anyone have one of these spare they would be willing to sell? Its a specific Personal Iris set of hardware that was changed for the later machines - the mouse is plugged into the side of the keyboard, then the keyboard to the back of the machine, pass thru fashion. I have tried keyboards from later machines but they arent recognised on boot up. If anyone can help me out I would be extremely grateful. Cheers! Shaun

Are office people really that, umm shall we say...slow?

by alan.pearson＠cramer.com

> This is correct, the primary problem lies w/ teachers spewing GIGO, > good teachers is percious few. Too true... my brother-in-law was doing a C++ course earlier this year and sent me one of his assignments to have a look at. Imagine my horror when I looked at the bit of code his teacher had given him to work from and the first 5 lines were "#include <whatever.cpp>" ... There have been an alarming number of interviews where I've asked a graddie (who's supposedly been studying Java for a year) what the significance of java.lang.Object was, only to be greeted by incomprehension. What do they teach these people? At least they've moved towards Java now, 5 years ago I used to ask graddies who "knew C++" what a pointer was and get answers like "it's that arrow thing on the screen that you move around with the mouse".

PCjr Stuff

by mbbrutman＠magnaspeed.net

There were a few 3rd parties that made hard drives for the PCjr, both MFM and SCSI versions. The SCSI ones are really interesting to me - there was a Future Domain TMC850Jr controller that PC Enterprises sold that attached on the side, and a card sold as part of an upgrade package by RIM that went in the internal modem slot. Unfortunately, I have neither - and I'd love to have one. I imagine that the SCSI solutions can be faked into using a SCSI Zip drive, which would be awesome .. Jr heads ... here is my contribution to the web: http://mail.magnaspeed.net/~mbbrutman/PCjr/pcjr.html I have the tech ref, the service book, and other goodies. I also wrote a cartridge & system ROM dumping program - might be handy if anybody ever decides to start copying the old cartridges. (Email me for source & .EXE) Mike

Altair32 2.10b released

by RCini＠congressfinancial.com

Hello, all: This weekend I posted the latest code release for the Altair32 Emulator. Right now, it's feature-complete except for the Altair Integrated Debugger, a fully-integrated debugger based on the one used by Jim Battle in his Sol emulator. There are a few known issues with this release: * Programatic access to the paper tape doesn't work properly for some unknown reason. So, for example, using the toggle-in bootstrap loader to load and run Altair BASIC 3.2 from tape doesn't work. Execution is never transferred to BASIC. Loading BASIC in the form of a memory image still works fine. Tape access has been sped-up by fully buffering the tape in a buffer and reading from the buffer. * Other BASIC versions, such as 8k (4.0) and Disk Extended BASIC, don't work properly. They seem to crash the emulator after the "MEMORY SIZE?" prompt. A quick trace of 8k BASIC shows some possibly strange IO port usage. * Emulated floppy access with the included disk images doesn't work properly. I can boot the emulator to CP/M and are able to see the console output but the CP/M BIOS doesn't seem to register console input. I've asked for a copy of the CBIOS source that relates to the CP/M image (borrowed with permission from the Sysun on-line computer museum) so that I can track this one down. I suspect that it's a problem with the emulated status register for the console serial port. Enjoy! Rich ========================== Richard A.

DEC Lab 11/40

by djg＠drs-esg.com

You had already gotten a bunch of good responses, you noticed all the foam was falling apart like in mine, I cleaned it all out so bits of stuff wouldn't be floating around. I used some furniture foam where I needed thick and soft weather stripping foam for areas like the air feed to the disk pack. If you pull the fan to replace the foam check to see that the duck bill which cools power supplies doesn't have dust blocking the end. I also had to replace the nicad battery pack which retracts the heads when power fails. If it isn't leaking you can see if it took a charge after the drive has been running a while or try charging if you got a power supply and then load test. You can also test by carefully pulling the head forward with the drive powered off. It will suddenly yank it back when you hit the switch (watch the fingers). Don't pull it far enough that it starts to get to the head load ramp, it should pull back before that. If you think you might have some dropped packs what I do is with cover off watch the reflection of something at the edge of the disk where the head loads. Blip the run switch to start the pack spinning and as it slows down watch for the reflection to move. If so the edge is bent. I don't know how much is safe, I have a couple I declared unsafe and a couple with just a slight change which worked fine. For packs that weren't stored in bags I clean them before using. I use alchohol wipes then "air" can and a lens brush to remove all I can. Look at various angles, the proper lighting angle makes the dust visible. I then let sit in the drive for a while, spin it up then run a program which quickly steps through all tracks. Frequently I get a little ping on a track on the first pass or two but the moving head seems to knock the dust bits off. If the head isn't moving it can sit pinging at a track which doesn't seem like a good thing. If after two passes the disk isn't quiet I try cleaning again or put it in the trouble stack. Check/clean heads after this. Also keep the finger on the load button and hit it if things sound too loud. I also have some PM procedures on my site which a company wrote for maintaining their drives.

Go into Extended Mode (both shifts down at once to get the "E" cursor), then press the command key you want while keeping Symbol Shift held down. Good old Sinclair keyboards... the keyword entry thing worked ok on the ZX80/ZX81 IMHO because they were such horrible "key"boards. Not so sure about the Spectrum, there were just too many keywords to find, even if you knew where to look it was still a pain to type in a listing from a magazine :-) I recently got hold of one of the 128K Spectrum+ machines - the ones with the QL-style keyboard. Firing up the 128K BASIC allows you to type in a program character by character - I would have thought that would be an improvement, but I find it to be just as nasty as the 48K BASIC's keyword mechanism because the keyboard layout is non-standard. I ask you, putting the " on it's own key :-) -al

Network protocols - RS232 Serial

Mine also says 'Digital Products Inc' on it. > I've got a couple of different models here. ----------------------------------------------------- Well, I guess Product*S* is appropriate after all... They did indeed make quite a few different combinations, as well as the PrintDirector and DeviceDirector Printer/Terminal port sharing units, but I don't see yours listed in any of my literature; musta been older or newer than mine. I do see an NC7 (4S/3P) and some of the MultiSpool Print Directors were S/P combos. These are serial-only single-board babies, 16 RJ-45's along the back of the board, using standard DIP 256x1 RAMs. When you look at it, it sure doesn't look like $3000 worth... Now if they'd put some LED's on the front panel, say 4 per port, all blinking away merrily... We used them in two applications: One was collecting data from a bunch of AIM65's (later replaced by PC's) monitoring stock thickness in a brass rolling mill and sending it to a central Cromemco (also later replaced by a PC), and the other was a bond trader who used them to broadcast news of a new issue to his clients over dedicated lines, so some of them have been modified to simultaneously broadcast 1 port to the other 15 ('cause ya couldn't have one client getting the news before another, even at 9600 baud; that's how hectic the bond business is). mike

what RAM for this printer memory board?

by ysgdhio＠yahoo.com

I just got a memory board for my HP IIIp. The board only has 2MB on it, but there are 2 rows of empty 20-pin sockets that lead me to believe I can add another 2MB for a total of 4MB. I'd like to do that in the most cost-efficient way possible. The board is marked "(C) 1991 Pacific Data Products" and "P/N 012186". The soldered-in RAM is mostly marked "HY534256S-70", although three chips are "HY534256S-80"(?) Thanks in advance.

That awful Spectrum keyboard

by optimus＠canit.se

I found a keyboard-less Spectrum at the salvation army, and I got it at only 15 SEK. Great price, that's about one GBP. So I proceeded to mix and match a working Spectrum out of one and the one I already own. The keyboard ribbons on my old one were really beat up, so I took the matrix (and ribbons) off the one without a keyboard and transplanted it into the old one, which turned out to work this time. It was probably just a disagreement with an AC-DC adaptor or the tuner in the TV. So now I've got a working Speccy, with a luxurious on/off switch and all. The keyboard is... interesting. So far I've worked out how to generate all characters on the keytops (letters, keywords and symbols) using CAPS SHIFT or SYMBOL SHIFT. I've also discovered how to print the keywords listed above each key, by pressing both SHIFT keys in order to enter the "E" input mode. But I'm lost as to how to print the keywords and characters listed below the keys. No combinations of SHIFT keys seem to work out. -- En ligne avec Thor 2.6a.

OT: power & ground for wirewrap boards

by zaft＠azstarnet.com

Gang, Sorry for the offtopic post, but I need y'alls expertise... I've got a wirewrap SBC that I'm working on (6502-based system). I've got my wirewrapping skills down pretty well and that part is not a problem. For the power and ground connections for each chip, a friend suggested I should solder 16-gauge wire from a tie point or the power connector straight to each chip and/or its bypass cap. The only 16-gauge wire I have is stranded, and it's a mess to work with -- too large to work with easily and the strands mean it won't really bend and stay on the tie point or pin. Can someone who's done this successfully tell me how I should do this? Thanks! Gordon

What I'd like to do is to be able to make disk images of all (okay, maybe just 'many') of the old DOS floppies I have so that if they disks get trashed or the bits fall off I can remake 'em. I'm assuming I'd probably be making these archives from a Windoze box although DOS or even FreeBSD or Linux is a possibility. Thanks in advance. GZ

What's the deal? Yes... they really are that dumb... at least the ones that I have to support here are. I regularly have to mark cables and drives, or they screw things up. It seems to most staff here, if it doesn't fit, force it... so the fact that most cables only fit in one place doesn't stop them (I have found VGA monitors plugged into MALE 9 pin serial ports... yes, it can be done... lots and lots of force, but it can be done!). Of course, sometimes labeling everything can backfire... thanks to my efforts to make my offices idiot proof (make something idiot proof, and they'll build a bigger idiot)... my boss now thinks EVERYTHING can be made that way... he routinely complains that he needs written directions on how to fix problems with the WIndows NT network... so in case something unexpected goes wrong while I am out of the office, they can fix it. He doesn't grasp the difference between looking for a port marked "Mouse" and diagnosing Win NT problems. So yes, office people CAN be that dumb. -chris <http://www.mythtech.net>

PowerWare 6000 UPS

by pete＠dunnington.u-net.com

Probably off-topic due to (lack of) age, but... I have inherited a PowerWare Prestige 6000 UPS. Anyone have any experience of these? It doesn't seem to like my mains supply. It trips the 16A (240V supply) breaker as soon as I turn it on, whether I have two, one, or no battery packs connected, and with or without any load. I've followed the procedures in the manual. It's rated for 19A at 240V, so I'm going to try a larger breaker; I'm told it always did have a large switch-on surge. Any other clues? -- Pete Peter Turnbull Network Manager University of York

In many cases, including the situation Russ is referring to, it's a matter of a manufacturers warranty. If I do *anything* to the monitor, and two weeks later the tube dies, the customer has no warranty rights. It's in the customer's best interest for us to send the monitor back to the maker for repair. Glen 0/0

Just wondering you any of you guys know other in the KC Missouri/Kansas area interested in starting an informal classic computer group/club? Within a convenient radius is Omaha, NE, Des Moines, IA, and Topeka KS as well. As the usual sources of older equipment seems to be drying up, maybe those of us with an educated eye can network a bit more efficiently around here. Spread the word and have those parties e-mail me.

Are office people really that, umm shall we say...slow?

by Lee.Davison＠merlincommunications.com

Speaking of which, I'm planning to replace a CRT this weekend and naturally don't want to get a big shock. I've read that one way to discharge a CRT is to use a well insultated screw driver with an alligator clip/wire on the shaft of the driver comnnected to ground, and then insert the end of the driver under the suction cup where the anode meets the tube. Any thoughts on this approach? Don't connect to ground, connect directly to the wires that rest on the coating on the back of the tube. This will ensure that you discharge the tube. Also, if neither CRT has been on for a week, how much charge likely remains? Up to all of it. Also be aware that a tube that has been disconnected for any length of time may self charge due to electrolyte stresses. Not enough to harm you but enough to make you drop the tube in surprise.

NCR X-Station?

by donm＠cts.com

At swap today I picked up a neat little package made by AT&T/NCR in the early '90s. The package is 9.75W x 9D x 1.25H and looks rather like a book. The front carries only a push switch and an LED, while the rear has DB25F Parallel, RJ? and DB25F EIA, RJ? AUX, HDE15 VIDEO, and RJ? and OS/2 KEYBOARD connectors plus a concentric power input connector. There is an Intel 80C32 microcontroller, various static RAM chips, and a specialized NCR/ADDS SMD chip that pointed to X-Station information via Google. Anyone ever run across one of these critters and have any information on it? Also picked up a dual port SGX full length network card using DA15M connectors. I was intrigued by it carrying an NEC V50 PLCC chip. First I had seen. - don

Computer collectors meeting in The Netherlands 27 oct.

by kees.stravers＠iae.nl

Hi, I don't know if it has been mentioned here already, sorry for the dupe if it has been. The members of the Dutch computer collectors mailing list CVML are having a computer swap meeting for the third time this year. The focus will be on trading, where the members will bring machines they don't want anymore (and of course a few to show off with :) ). The list members mostly collect 8 bit micros from the 80's. Last time the meeting was a great success for me, I arrived there with a van filled with computers, and I left with only one :) The meeting will be held on october the 27th in the TwinType building at the Valkenierslaan 47 in Breda from 10.00 to 20.00 hours. There is a (Dutch language) web site at http://www.xs4all.nl/~rimmer/cvml/ For more information you can mail ton.brands(a)xs4all.nl Grtz, Kees. -- kees.stravers(a)iae.nl http://home.iae.nl/users/pb0aia/ http://www.vaxarchive.org Net-Tamer V 1.08.1 - Registered

by mythtech＠Mac.com

>I'm doing a Tony here, but... >Is replacing the connector/cable on a modern monitor so difficult that it >can't be accomplished without sending it away? I have replaced many monitor connectors (all VGA HD15s). They aren't usually TOO hard to do. The hardest part I have run into is usually getting the old one open. If I am doing a total replacement, it isn't an issue, as I can just cut it off... but usually, for broken pins, I try to extract the bad ones, and insert new ones... in which case I will dremmel open the old casing, and replace the pin. Molded pins can be tough, but a hot needle will usually melt away enough of the plastic to slip them out. Then a dab of hot glue on the back side holds the new pin in place. Certainly in my book, easier, cheaper and faster then sending the monitor out to be repaired... but I know what I am working on... I would never expect a regular office person (and in some cases, even a regular IT person) to be able to do it. -chris <http://www.mythtech.net>

ASR 33 Emulation - help!

> I don't see how. I have some documents (I think written by Ward >Christiansen) about how XModem and YModem work and it seemed fairly >straightforward to implement the protocol. XModem isn't exactly that >difficult of a protocol to support 8-) Hey, since there is a discussion of protocol's going on... does anyone have the specs needed to write an implimentation of the I-modem protocol? (that's I as in "Eye" or "Myself"). I know it was created by John Friel (at least, that is what I learned when researching the protocol). But I can't find any real specs on it. The only other thing I know about it is Procomm Plus version 1.1B supports it. I need it to download data files off one of my systems here, and I want to write a nicer download front end for it. Right now I have to do it manually thru Procomm... not that it is a big deal for me, but I want to be able to let some of the other office staff here take care of the job, and for them, using Procomm and sending ASCII commands isn't a good idea (they will screw something up... they have in the past, and they will again in the future). If I can get the specs on the protocol, I can write a program with a nice GUI to handle the logging in, and selecting data, and downloading it... not to mention, then I can do it on the Mac, which means some of these people can do it right from their desk. I'm hoping some of you wizards out there might have the info I need. (I have exhausted Google among other search engines looking for it) Thanks -chris <http://www.mythtech.net>

Those HDD15 connectors are a bit fiddly, and in a commercial environment it makes sense to have an "approved" repair done if the equipment is very new, as it has implicatons for the warranty. Also, some cheaper monitor cables use twisted pairs instead of coax (yuk!) and if you cut off the moulded plug, it can be a pain to sort out which wire is which. -- Pete Peter Turnbull Network Manager University of York

Does anyone know how to make a PC emulate an > ASR 33?? Most PCs running Windows either have installed or can have installed on them a terminal emulator named Hyperterm which can do what you want. However, the serial ports on PCs are RS-232C ports, while many ASR33s had 20ma current-loop serial interfaces. You'll need to either get a converter, or a separate 20ma current-loop serial card for the PC. BlackBox used to have both of these, but they got acquired, IIRC, and I can't recall the new firm's name... For the paper tapes, once read in, you can just use Hyperterm's file transfer... oops, NIX that, I see ASCII mode is not among Hyperterm's file transfer options... Hmmm, you may need to use something like PROCOMM PLUS or ProcommPlus/Win... they still have the ASCII transfer mode. Or just run DOS and use COPY, I did that with a PC and a friend's CNC machine a few years back, worked quite well. hth, -doug q

Looking for PDP-1 listings

by dpeschel＠eskimo.com

No, not PDP-10, PDP-1. Thanks to Al Kossow, I already have the manual for MACRO, but he didn't scan the source listings (which are supposed to come with the manual) and I haven't found anyone else who has a copy. Any other listings (DDT, TECO, MIDAS, the LOGO programming language, TVEDIT or any of the timesharing systems) would be interesting too. I'm trying to spiff up the cross assembler that comes with Bob Supnik's simulator, so that's why MACRO and MIDAS are important. I'm also trying to understand Peter Deutsch's LISP, so that's why DDT is important. The others would be just for fun. I already have Spacewar from http://lcs.www.media.mit.edu/groups/el/projects/spacewar/sources/ but maybe someone has a newer version. Thanks, -- Derek

IBM Punched Card equipment docs

by mhstein＠usa.net

IBM PC system meant something different back then :) Here's the list, for Norm, Erik, Dave and anyone else who inquired or may be interested; a little musty but generally in good shape. REFERENCE/OPERATION MANUALS 24/26 Card Punch/Printing 46/47 Tape-to-Card Punch 56 Card Verifier 65/66 Data Transceiver/Printing 77 Collator 2, 1 no cover 82/83/84 Sorters 101 Electronic Statistical Machine 2, 1 no cover 402/403/419 Accounting Machine 3, 1 no cover 519 Electric Document-Originating Machine 2 519 ditto, Principles of Operation 528 Accumulating Reproducer 548/552 Interpreters 549 Ticket Converter 550/551/552 Card Interpreters - Principles of Operation 557 Alphabetic Interpreter - Preliminary 601 Electric Multiplier - Principles of Operation 602-A Calculating Punch 604 Electronic Calculating Punch 2 650 Magnetic Drum Data-Processing Machine 654 Auxiliary Alphabetic Unit CUSTOMER ENGINEERING REFERENCE MANUALS 602-A Calculating Punch - w/wiring diagram 77/85/87/89 Collators 402/403/419 Accounting Machine w/wiring diagram 24 Base 24/26/27/28/46/47/56/65/66/526/534/536/824/826/834/836, Wiring diagrams for 024 and 056 only Also, some interesting pamphlets about system design, procedures & control with these machines and I'll even throw in ref manuals for a Honeywell 400 and the Burroughs B200 Series (not the famous B205, but 250-280). The stack is abt 7" high, wt. abt. 10 lbs. Don't know about any others, but FWIW, I see there's a 604 manual at: http://www.spies.com/~aek/pdf/ibm/604_OperMan.pdf What I'd like to do to save time & trouble is ship it all to Norm since he generously offered to scan it, and then you can sort out who needs and gets what. mike/ccs

Network protocols - RS232 Serial

by mhstein＠usa.net

That's the baby, all right, but both the units and the manuals say "Products"; guess when they made yours that was the only product they had :) And these are the NC16 serial-only model, HW or XON/XOFF selectable, no parallel ports (but I do have some S/P converters... :) And I was mistaken, now that I think back; the RJ45 model (which these are) can not select DCE/DTE, it's fixed (although I don't recall which). $2995 (no, no decimals in there) when new!!!! Just found the price list. And these later models handled binary data a little better. Did I mention modem/printer sharing, many-to-many? Or computer-less local e-mail & messaging (within 250 K of course)? mike ------------Original Message------------- Date: Thu, 18 Oct 2001 19:41:00 +0100 (BST) From: ard(a)p850ug1.demon.co.uk (Tony Duell) Subject: Re: Network protocols - RS232 Serial > > Now that the OT ramblings are dying down, a serious one (sort of): > > Anybody have a use for one or more Data Products Inc.

I was never a big Kermit fan. It came at the very end of the days when it would have been of most use to me (76-81). As a nearly charter member of Ward & Randy's BBS, I adopted Ward Christiansen's XMODEM protocol, and used MODEM/MODEM86 during those years. First time I saw it was a copy that came with an 8051 protoboard in '87 and it gave me fits, being generally much less capable than a clone of Andrew Flugelman's terminal emulator/transfer program (forgot the name). PROCOMM most closely resembled Andrew's program, so that became my standard terminal emulator under DOS, and later Windows. Regards, -dq

IIgs using hard disk 20

I have several of the > 3.5" form factor. If that size, do you have the model number? Ok, On the board: SMS MODEL OMTI 3 FAB 005298 REV A.3 ASSY 0005447 REV A Chipset is NCR 0380xxx family with SMS & OMTI labeling. Paper label on one chip says OMTI 3127 and repeats the assembly number given above. ROM is labeled 1002550-A, 3127(C). If a working one of these doesn't get the drive going, then the pro0blem was with the drive. But I was hoping I'd killed the controller with improper termination. It sometimes seems to work at first, but then craps out as it warms up. The drive activity light comes on and stays on at that point. I'd sure love to get the damned drive backed up... I think I have copies of everything on there, but perhaps not. Regards, -dq

Network protocols - RS232 Serial

by mhstein＠usa.net

Now that the OT ramblings are dying down, a serious one (sort of): Anybody have a use for one or more Data Products Inc. NC16/250 NetCommanders (Not to be confused with Diamond's NetCommander ISDN adapter)? Need to talk to your 15 vintage RS232 systems in the garage from one terminal? Need to have your single-port computer talk to the 15 terminals throughout your house? Need to have your 16 computers talk to each other about you while you're away? And all at the blinding speed of 19200 baud? Or do you maybe just need another obscure piece of hardware sitting on your mantelpiece? Then THIS IS THE DEVICE FOR YOU! Original cost SEVERAL 1000 $$'s each! A 16 port cascadable RS-232 switch/hub/256K buffer, DCE/DTE programmable, allowing each device to talk to any other, either pre-routed or addressable in the datastream header; simultaneous multiple paths possible, even at different baud rates. Software setup (although they'd need 2 new AA NiCads to remember), unfortunately an austere front panel with no pretty blinkenlights. BUT WAIT! THERE'S MORE! If you order right now, I'll throw in your choice of P/S or S/P converter, parallel or serial buffer, auto printer switch or serial or parallel range extender! Any serious interest? As usual, in the Toronto area, but if ya really can use one of these, unlike the Cromemcos it's almost practical to ship; not very heavy. Might need a few $$'s though, to cover my time in checking one out and copying the docs, since there's only one copy. mike

I guess it can step up the power. The game uses 2 D cell batteries connected in series, so it gets 3 volts input power. Humm... thinking about that, the choke coil could actually be a light weight transformer then (maybe? I'm not an EE, so I am guessing since a trans and a choke both have lots of wire wrapped around a magnetic core) I will have to see if I can get a chance to draw up those schematics, that will help tell more about it I am sure. Heck, I have to take it back apart anyway, I need to either oil the motor, or replace it. The game seems to still be working (thank god no perm damage from the battery leak), but the motor starts to slow and stress at certain points. -chris <http://www.mythtech.net>

punch cards, PPT

by mhstein＠usa.net

Hi Lawrence, Don't know yet what'll happen to the punch & cards; still trying to sort it out, along with the old IBM docs. Will keep you advised if it doesn't go to Erik in Holland or one of the other enquirers. Can't interest you in some 8 ch. punched tape equipment instead? Nice Burroughs optical reader & punch, and a box + of mylar & paper tape, assorted lovely pastel colours and black :) Hope u don't mind if I put this reply on the list, in case someone else can benefit from your tip about the cards. And you haven't told me yet what Cromemco cards you need. mike ---------- From: Lawrence LeMay[SMTP:lemay@cs.umn.edu] Sent: Wednesday, October 17, 2001 6:13 AM To: M H Stein Subject: Re: punch cards I want to eventually connect a card reader to one of my PDP 8's, and thus I would want a method of punching some cards ;) I dont have the room nor the ability to move a large IBM card punch unit, so a small unit would be desirable. I'm still looking for a omnibus card reader interface card. So no, I dont have a specific application, but i'm not looking for something to hang on a shelf and point at occasionally either. I do plan to use it eventually. By the way, it is still possible to buy blank punch cards you know. That guy on ebay who is selling the selection of different types of punch cards does sell them. I think his ebay name was key29 or key26, something like that.

New aquisitions: PCjr (minus power supply) and Amstrad PC 6400

by mythtech＠Mac.com

>How much should a PCjr PSU run me? I will do some digging, I *might* still have a power supply or two kicking around. I had shelves full of PCjrs not to long ago, and I threw out all but one complete unit (PCjr, side car expansion thingy, wireless keyboard and the wire for it, power supply, monitor). I tossed all the PwrS's back then too, but I *think* I have seen one or two still floating around (if you don't mind that it will have a number written on it in white paint). Unfortuantly, the room they would most likely be burried in, the lights are broken right now, so until I get around to changing the ballast, I can't see very well (I just took a quick look with a flashlight, but when I say they would be burried in there, I really mean burried, it is about waist deep in one giant pile of old stuff). If I still have one, I would be willing to give it to you/trade it to you. (you can't have my last one, but worst case, I can tell you what the pinouts are, and the voltages on them, so you can always try to build one yourself... although they do have an odd right angle connector IIRC and that might prove hard to find/replicate) -chris <http://www.mythtech.net>

Rescue Needed: SGI PowerSeries III 4d/48VGX FREE!!

by mgoodman＠hms.harvard.edu

Please help find a home for this system: This is one unique system giveaway...last of the dinosaurs wants a good home; and we want the space it occupies. The SGI PowerSeries III 4d/48VGX is a beast of an IRIX system (or was in it's day). This system was a graphics workhorse that ruled the world of high-end Structural Biology Molecular Modeling; chewing up other systems in its wake. Today it is a fossil that could have high appeal to a computer archeologist. This system is about the size of a LARGE refrigerator, runs on 220V power (and knows how to USE IT!!). The system is currently not in operation; but for those that know how, or want a unique project, it can be a serviceable working unit. Expensive to purchase originally; reputedly around $250K, This is a classic system that is destined as a museum piece...it would be a real shame if this ends up in the being discarded. Here's a couple of links on this unit and its family, for those with interest: http://www.reputable.com/~skywriter/pstech/index.html http://www.geocities.com/SiliconValley/Pines/2258/4dfaq.html You must be able to remove the system via your own transportation. The system is located on the Harvard Medical School campus in Boston, Massachusetts. Please: Serious Inquires only...remember you must truck this system out on your own; and removal in a timely fashion would be appreciated.

Are office people really that, umm shall we say...slow?

by fernande＠internet1.net

I just went to a local computer show today. I was happy to find that a few vendors had components available from disassembled computers or whatever. I picked up a 3com 3C905-TX PCI ethernet card, an ATI Mach64 video card, and a very nice Sound Blaster 16, all used of course. The Mach64 had "Monitor" written in marker on the slot cover. Do office people really need to remind themselves where to plug the monitor in? I have also seen a 3.5" floppy drives marked "hard drive a:" and the 5.25" floppy, marked, "floppy drive b:". What's the deal? I also picked up a new AMD K6-II 500 to replace my IBM 6x86 233, and a nice new heatsink/fan for it too. Hopefully I'll have my re-made socket 7 setup, up and running Linux soon :-) Chad Fernandez Michigan, USA

Redactron WP

by jeff.kaneko＠juno.com

Having had some actual hands-on experience with these beasts (I used to be a service droid for a Redactron Dealer), I say deep-six the mutha'. They're pigs to work on, and utterly useless without the 'printer' (actually, it's an IBM Selectric I typewriter mechanism, with a belly plate *packed* with solenoids). Electrically, not very interesting; most of the space in the cabinet is taken up by the powersupply (ya gotta source enuf current to actuate all them solenoids). The 'brain' (if ya wanna call it that) of the thing is just a 12" square board, packed with custom ceramic SSI or MSI chips. There was another board with all of the SCR's (I think, geez, that was like, twenty years ago). ANyways, one of my fondest memories was the day I had to service on one of these puppies at the Aberdeen Proving Grounds in Maryland. Those GI's schlocked so much wax on the floor in that office, the damned umbilical from the cabinet to the selectric was *stuck* to the floor! I gave it a good yank, and the wax flaked off the umbilical like so much dandruff. Yeek. The later Burroughs Redactor II's and III's were 8085 based, and are of more interest . . .

Although, I don't think they would have, as IIRC, they would be too tall, and they have the dust cover plate for a PC on the back, which just would have made no sense in an Apple II) -chris <http://www.mythtech.net>

I assume the tritium component is a modular part of the device, as it has a rather short half-life (and IIRC, the last production facility was closed down). -dq

New aquisitions: PCjr (minus power supply) and Amstrad PC 6400

by SUPRDAVE＠aol.com

The IBM PS/1 models 2011 and 2121 both use the same monitor with power supply inside. I get several emails from people that buy the CPU but didnt get the display with it. PCjr power supplies show up every once in a while around here, especially at hamfests. In fact, I bought a jr a few months back with a second story floppy drive that connects to the main unit. I'd like to hook up my PCjr hard drive to it also. In a message dated 10/17/2001 11:43:23 AM Central Daylight Time, lgwalker(a)mts.net writes: << The 1640 reminds me of the IBM 2011 with the power supply in the monitor unit. There was an informative thread a while back on the mail list in the spring of 1999 regarding the 1640. I have one but alas no K-B. I did win one on e-bay but was never able to get a reply from the seller. I also have a PCjr and like you don't have the PSU. They come up on e-pay occasionally but either I haven't had the money at that time or else the seller wouldn't ship to Canada. I have managed to acquire some manuals for it, including the IBM one, however, as well as some cartridges but they are buried somewhere among my stuff which is still in disarray due to my move this summer.

Hard Card (was Re: IIgs using hard disk 20)

by mythtech＠Mac.com

> Could it have Been a Plus Systems HardCard? I know that they did a PC > hardcard, I don't know about an apple II version... they were acquired? by > quantum many years ago I just dug out my 2 "hard drive on a card" units (not to be confused with a "hot dog on a stick"). One is a Plus Hardcard (says so right on it), I have NO idea what kind of a drive is connected to it (4 small ribbon cables marked R/W, Encoder, Motor, Rotor... don't know what kind of drive connects that way), nor do I know anything about the size (40mb?, see below) or setup of the drive. But the specs may be available on Quantum's (well, now Maxtor's) web site... I do know I have seen Hardcard info there before. The other one doesn't have a name per se on in. The physical drive is marked Kalok, Octagon Disk Drive by the Kalok Corporation. Model# KL330. However, I think that might just be the OEM drive the unit manufacturer used. It looks like maybe an MFM drive (2 card edge connectors that look like 5.25 drive connectors). On the back of the unit is a sticker marked Part#: (blank), Model#: CARD30R, Serial# 9790, Date: 1/90. If the date is right, then this thing is WAY newer than I thought it was. At one point I must have had some specs on it, as I have penned onto the drive the setup of it (616c, 4h, 26s, 32mb). I flipped thru my binders of tech notes, and I didn't find anything on the Kalok drive, but I found a page of notes on the Plus hardcard... tells me how to change the IO and IRQ settings, as well as how to repartition it as one drive. Seems it comes as 2-20mb drives, but needs a device driver to work, repartitioning it as one 40mb allows it to work under DOS 6.22 without drivers. I don't think I have the drivers, and I don't think this is originally my page (it is dot matrix printed and that doesn't jive with the rest of my notes), so my guess is, I found it in a closet somewhere and clipped in into my binder. Well... hopefully some of you cared about all that... if so, there is a picture of the two drives at <http://www.mythtech.net/hardcard.jpg>. If not... sorry to waste the bandwidth. -chris <http://www.mythtech.net>

IIgs using hard disk 20

by lgwalker＠mts.net

This didn't seem to get thru last time. Sorry if it's a duplicate post. L. Here's some gleanings from my database of a2gs inf. I believe it was supplied by Supertimer on the csa2 newsgroup. --------------------------------------------------------------------- There are two things you need to do to get the IIGS usable. First, get a hard drive for it. http://www.allelec.com/ Alltech Electronics sells an internal hard drive for the IIGS that is a hard drive on a card. No extra controller needed. It is an IDE controller plus notebook mechanism. It costs $59. For that price, you also get the most modern Apple IIGS System Software, GS/OS (System 6.0.1), which is normally on six separate floppy disks (a hard drive is needed to get the most out of it). You also get tons of freewares and sharewares. The hard drive is called the Focus hard drive card. Look for it on the Alltech site. The other thing is memory. Alltech (see above for web site) also sells the Sirius RAM card. They are revising their web site, so this product may not yet be on there, but just call them and ask. It is a 0-8MB memory card that can be expanded in 1MB increments using 1MB 30 pin SIMMs. I'm sure you have an old 386 lying around that you can gut. Only the IIGS can run a graphical OS somewhat similar to MacOS. The IIGS' OS can, with the proper software, generate printed pages on high resolution ink-jet printers and laser printers with TrueType fonts, an Apple (same as Mac) style GUI, and the use of the same keyboards and mice as the Mac (in fact, ADB was first used in the IIGS before being used on Macs...pre-GS Macs used "telephone" style keyboard cables). The IIGS has built in support for 15Khz analog RGB color. The IIGS itself has a 4096 color palette and is capable of theoretically throwing up to 3200 of those on screen at once. The monitor the IIGS uses will also work on the Amiga and Atari ST and their monitors will work on the IIGS. some URLS http://www.allelec.com/ http://www.sequential.com/ Sequential Systems. http://ground.ecn.uiowa.edu/ I believe the A2 FAQ by Rubywand and a bunch of other stuff is still on this site or you can find it regularly on the csa2 n-g. There used to be older FAQ by one Nathan Mates a notorious csa2 flamer who, in a snit, removed it from circulation. If you contact me off-list I MIGHT be able to tell you what was in it. Since I've had an A-gs monitor for years and by the Law of Affinity knew that a GS would eventually find it's way to me (thanks Rich) I've kept this info and even the GS manual. Lawrence SNIP > I was hoping maybe they used the same ports, and I might be able to use > the HD 20 with my IIgs so I can add a hard drive to it. > > Anyone info would be great. > > > > -chris > > <http://www.mythtech.net> > ------- End of forwarded message ------- Reply to: lgwalker(a)mts.net

IIgs using hard disk 20

by mythtech＠Mac.com

Does anyone know if an Apple IIgs can use an old Macintosh Hard Disk 20. The Mac HD is NOT scsi, but rather uses the disk drive port on a Mac. It was designed to work with older non scsi macs (128k 512k), and could be daisy chained thru the disk drive ports (at one point, I think I had 3 HD 20s and a 400k drive connected to my 128k Mac). The IIgs has a disk drive port, and visually, the 3.5" drive I have for it looks just like the 3.5" drive I have off an old Mac Classic (I have to go off visual, as the one from the Classic has no labels or other markers beyond the apple logo... don't know why, that is the way it was when it was given to me). I was hoping maybe they used the same ports, and I might be able to use the HD 20 with my IIgs so I can add a hard drive to it. Anyone info would be great. -chris <http://www.mythtech.net>

One gone, one awaiting its fate: T300 dual floppy PC semi-compatible, no monitor (but std RGB OK), spare KB, 2 sets of 3 manuals, 123 & dBII, diskettes & some tech info; also service info & schematics for T100. Good for converting 360 to/from 600 Kb diskettes. Headed for landfill if no interest. mike

Available in NJ: BYTE magazines, 1982 and 1983 complete

by ysgdhio＠yahoo.com

In the process of reclaiming basement space for other hobbies, I have unearthed a box containing two complete years of BYTE magazines, specifically 1982 and 1983. They are in very nice condition. If you want them, please reply to me directly to arrange pickup in central New Jersey, just off the Garden State Parkway. At a later date, I might also be uncovering at least one complete Sony SMC-70 (CP/M) system, perhaps up to two more system units and a number of add-on cards. These probably won't be free, but certainly not eBay prices. (I'd work a trade, but I really really need the space) Again, reply directly if you'd be interested. Thanks.
