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

Quite possibly a substantial charge... to verify this, perform a case study: convince a clueless office PeeCee "expert", or some random Micro$oft-brained IT manager, to wet their fingers and touch the right places.

anyone in the greater KC area interested in classic computers

by ghldbrd＠ccp.com

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
