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.

PCjr Stuff

Yep. The only restriction on Linus's final blessed tarball is a MMU. ELKS (and several other embedded/handheld ports) don't. ELKS will run on MMU less 'Intel' systems.

List Maintenance

Mike, I had to abandon the former world.std.com account as I was getting between 55-60 UCE/SPAM a day. After a while even wholesale deletes take too long. Whats this address your babbleling about as this address is getting on average 3-5 UCE/SPAM a day. This bugs me as I've taken pains to keep it out of circulation.

GenRad Futuredata

by clandrum＠monumental.com

I have two Genrad Futuredata 2300 systems and accompanying software and am hunting for other owners. Specifically, I am looking for a 2716 or 2732 EPROM burner that these units supported. This was a small box with a ZIF socket that conected to a Microkit board on the Futuredata S100 bus. I have software for these machines and can exchange for leads on an EPROM box. - Craig Landrum CTO Mindwrap, Inc. home: clandrum(a)monumental.com work: craigl(a)mindwrap.com 540-675-3015 x 229

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

Archiving floppies?

by zaft＠azstarnet.com

Does anyone have any recommendations on software (preferably free) for archiving old DOS floppies? 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. Figuring out a suitable explanation to make this agreeable to them shouldn't be too difficult - after all, the unit is safely unplugged from the mains socket, right? ;-) This will also demonstrate the correlation between failures of evolution and modern hiring practices.

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

The LACK of knowledge, or simply WRONG knowledge coming out of these people was frightening, frightening to the core that these people were going to graduate and get jobs running the IT infrastructure of the US corportations. The only good thing that came of it, it finally convinced my boss that a college education didn't mean jack... which got me a raise (being a college drop out myself) -chris <http://www.mythtech.net>
