FA: old computer sales and service video training tapes. Compaq Deskpro, Compaq Portable II, DEC Rainbow, AT&T 6300.

by rigdonj＠intellistar.net

I'm still cleaning house and I've just finished listing a bunch of video tapes on E-bay. These tapes were for sales and/or service training for several of the old PCs, including the AT&T 6300, Compaq Portable II, Compaq Portable 286, Compaq Deskpro, Compaq Deskpro 286 and the DEC Rainbow 100 and 100+. There are also a bunch of various tapes from the old ComputerLand stores. All of these tapes were propriatary and were only supposed to be viewed by authorized dealers. Consequently they are very hard to find. These are top quality tapes and are very informative. Take a look; http://cgi6.ebay.com/aw-cgi/eBayISAPI.dll?MfcISAPICommand=ViewListedItems&u…. Joe

H89 Computer needs good home

by jweder＠telusplanet.com

Hi... I do have some interest. Having lost my old Heath catalogs I can't quite recall what the H89 is all about, but I wouldn't mind taking the H8. Please let me know what kind of $'s you're looking for, and what all is included. Thanks! p.s. I did try emailing you directly but I had it returned with an error message. I'll try again shortly.

RMA, RTMA, EIA and one more

by r.stek＠snet.net

After the RMA, RTMA and EIA published standards, aother industry association tried to make some sense of the various computer connectors. The retiring president James McDonald of the Electronics Industry Engineers' (EIE) tried unsuccessfully to promulgate yet another set of standards for computer inter-connects. This was known as old McDonald's EIE I/O.

AFAIK, all Amiga mice are dumb quadrature mice with two buttons, and their interface consists of 5V power, ground, four quadrature signals (2 for X and 2 for Y) and two button signals. A Sun mouse has a proprietary encoded interface that uses three (or four?) wires. I suppose you could rig one up to a serial port, if you wrote a suitable driver (might also need a level translator). -- Pete Peter Turnbull Network Manager University of York

Mine is in the smae workshop. Not ideal, but I'm careful where I let the swarf go (metal swarf is quite heavy so it's not too hard) and where I lay disk packs. Now the arc welder is a different story. The spatter from that can go everywhere, so it's in the garage not the workshop/computer room. -- Pete Peter Turnbull Network Manager University of York

There's a web page somewhere describing exactly how to do that for a Microsoft mouse. -- Pete Peter Turnbull Network Manager University of York

Anyone know where I can get MS02-CA RAMs for DECstations cheap? I need about 120 of them and I don't want to spend $7000+. Thanks. Peace... Sridhar

Encoded as "[ Attachment (multipart/alternative): 3829 bytes ]", so if you had HTML display turned off in Eudora, it probably just showed you the flat-ASCII version, which was there as well as the cruft. -- Pete Peter Turnbull Network Manager University of York

(OT) Acorn RiscPC 600

There are two long L-shaped locking pins that hold the case together at the back and two near the front of the slice. Pull the back L-clips out and look for two circular clips with small (3mm or so) tags on. Rotate them and pull them out. Lift off the slice and you can get at the HD. It will probably be a standard IDE interface. If you really want to get help with this machine, try joining up to the newsgroups comp.sys.acorn, comp.sys.acorn.announce, comp.sys.acorn.apps and comp.sys.acorn.hardware. Chances are, someone there will be able to help. I'm also a regular in CSA, CSA.misc, CSA.hardware and CSA.programmer. If you want, I'll scan in the relevant part of my Risc PC Welcome Guide and upload it to my i-drive. -- Phil. http://www.philpem.f9.co.uk/ philpem(a)bigfoot.com
