I'm a little late in jumping in this thread, but I get the digest version of the list and don't always see things immediately. I, too, have a near mint Canon Cat in original box with manuals - two manuals for the Cat and one for its daisy-wheel printer (which I do not have). I would be happy to loan the documents to any list member to copy (or better yet to make PDF files). I'd make PDF files myself, but I am already behind in promised Sol docs for Jim Battle. I realize that not many of these were made (about 20,000 IIRC), but I wasn't aware of its "collectability quotient." Anyone with an extra Altair want to trade? <g> Bob Stek Saver of Lost Sols

Win3.1 DDK

by rcini＠optonline.net

I'm looking for a copy of the Windows 3.1 Device Driver Kit so that I can get the debug symbols for use with Sourcer for some spleunking that I'm doing. I have the SDK, but not the DDK. Contact me off-list if someone has it. Thanks again.

DEC PDPs and Music/Sound Synthesis and DEC Humor Files

by rdd＠smart.net

Greetings, Last night I discovered that my DEC PDPs and Music/Sound Synthesis Summary was inaccessable. If anyone's interested, this, and quite a few DEC-related humor files, can be found on my web site from: www.rddavis.org/rdd/PDP.html -- Copyright (C) 2001 R. D.

2 awesome days of awesome finds!

by xds_sigma7＠hotmail.com

Well, I haven't had a chance to call the other place yet.... But the blinkenlights minis I have are a DG Nova 1210, 2 DG Eclipse S230's, DEC PDP-8/i, HP 1000-E, 2 Interdata 7/32's (soon to be one, as one is being traded), 2 TI 990/5's, and a Varian 620-L/100... Now I suppose I need to find a Modcomp, a Microdata, a CDC, a Prime, a Basic Four, a Bytronix, a Keronix, a Univac, a Cincinatti Milacron, a ROLM, and other manufacturers I can't remember.. I'm trying to have as many manufacturers represented as possible : ) Will J _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com

Back from the fleamarket

by optimus＠canit.se

I went on a shopping spree at the fleamarket today (well... =). First I picked up a SyQuest 88, mainly for the nice PowerUser case. Then I found an Atari mouse, and as horrible as they are (the only mice which are worse are the old IBM models), it would be nice to have at least one functioning original mouse. Then I went to Bruno, who had a whole lot of junk, as always. Amongst others, he had ISA accelerators - one Microsoft Mach-20 (No, M$ are not a hardware company, of course...) 286 accelerator and another 386 one. I bought a Kingston MCA 386 memory expansion and some odd Novell card, which leads us on to the questions: The card I bought is made by Novell, and has got the serial number 89935 and the application number 5657. Those numbers are noted with a marker pen. The words "BOARD 738-61-001 REV B" are screened onto the board. The board itself is a small eight-bit ISA card without any connectors (save for the ISA card- edge, of course). The construction is quite simple, consisting of four 74LS chips (one 7407N and three 74LS244N), a PAL, an AMD AM25LS2521PCB (another 74LS chip?) and a big gob of glue which conceals another chip. That's it, apart from some discrete components. Bruno told me that it's some kind of diagnostics card, but not exactly what kind of diagnostics card. Then he had a KA410-A board, which my research tells me is either a ?VAX 2000 or a VAXstation 2000. It's just a card and nothing else, though. I don't suppose it's really feasible to construct a working system out of it? My friend bought it for the SCSI chip, which he intends to use in order to repair a Supra Amiga SCSI controller. He also had a lot of Ungermann-Bass boards. They had some kind of VME-look-a- like DIN connector in the middle of one edge as well as some resembling D-sub connectors, all intended to plug into a back plane of some kind. They used a plethora of processors, both Motorola m68k, i80186 and i960. I finally bought a Datapulse 106A pulse generator, mainly due to its low price and the nice case (nineteen inch carry case with leather handles =). BTW, what's a Xerox FLEX? It's a small box with two centronics ports, a miniscule "parallel port" (so the label says) and a BNC connector. I also found a Zenith Z-station 235Sn, which looked like some kind of pizza box workstation, but I couldn't pry it open. What is it? -- En ligne avec Thor 2.6a.

Almost never did we find an RS232 device that > wouldn't work on the RS423 ports. Vague memory here. Almost any RS232 device should interoperate with almost any RS423 device. RS423 uses +/3.6V - +/-6V (IIRC) and usually operates at around +/-5V, instead of RS232's +/-5V to +/-15V, commonly operated at +/-12V. Also RS423 controls the slew rate in order to get faster signals further. It's also specified to be capable of driving several receivers (RS422 is a similar system but with differential drivers/receivers to go even faster/further). Unlike RS232, it's purely an electrical standard, intended to be used in conjunction with other standards (to get bidirectional interfaces, pinout definitions, etc). Oh, and in theory, it uses balanced receivers, such that the ground reference for the receiver is the same ground reference used for the driver; in other words the reciever signal ground pin is grounded at the transmitting end of the cable only. I've never had a problem mixing RS232 and RS423. The only possible problem I can think of is that some RS423 receiver chips are only rated for 10V inputs, but I've never damaged anything. -- Pete Peter Turnbull Network Manager University of York
