Multibus card haul

by skogkatt007＠yahoo.com

I obtained a bunch of MB (1?) cards from a fellow list member. Mostly Intel, 1 Matrox video card. Didn'y see a floppy controller anywhere, but I'll have to look closer. I have an Intel 286/20 chassis (the 20 doesn't mean mhz). Got to get me a keyboard and I'll be all set, right? O how I wish. There's an MDS keyboard on ebay, kind of pricey. Have to wonder where I'd stick the plug. No ribald suggestions please. So apparently my future has taken a turn for the very grim. As I'll be writing device drivers from this point until my death. Yep. It's all rawhide and buffalo chips from here on out. Maybe sum yu westerners can give me a hand. Fred, Chuck, Sellam. You're all westerners and cowboys apparently. Just rustle up some docs and software for me.

DEC VR14 TO-3 heat-sink socket?

by Tom Hunter

I finally got around to replace the dead TO-3 power transistors in my VR-14. They are mounted on the power supply regulator heat sink using TO-3 sockets made by AUGAT. Unfortunately one of the sockets has been broken by somebody in the past by over-tightening the transistor mounting screws. This may have been the root cause of the power supply failure as one transistor was doing all the work with the second transistor's collector lead having poor or no connection. There are two NPN transistors in parallel to double the power which is not a very good design anyway. I am trying to find the original Augat sockets. Here are some links to photos showing a closeup of the socket and the threaded insert with the originally crimped collector tab which broke out of the bakelite socket: https://drive.google.com/file/d/1MXclwHLDmoz_P2ub7tPc9oqSgrDbnTzR/view?usp=…, https://drive.google.com/file/d/1XJ7DpGA5Zx0ZSqDVL_gdBSWYuKdFHLlR/view?usp=… I would be grateful for any help trying to source these AUGAT made TO-3 sockets. I had no luck finding stock of these with Google and Ebay. Thanks and best regards Tom

Quoting/replying etiquette. (was: Re: I need to make some space.)

by Stan Sieler

Hi, PLEASE TRIM THE DARN POST BEFORE REPLYING! For example, Bill's interesting post about needing space was 75 lines long (#1)... The first reply included the ENTIRE MESSAGE. The second, from another very long time participant, was TWO !@#$%^& LINES OF NEW CONTENT, with *TWO COPIES OF THE ORIGINAL POST* (about 145 lines). I don't want to single out just that post ... I haven't counted, but I'd bet that the vast majority of posts include the entire OP, and replies! Some other post had three copies in today's digest. The basic guideline is to quote *just enough* for the reader to understand what you're referring to. (Whether you quote below or above is another subject entirely :) Please have consideration for *EVERY* reader of this list, our disk space, and our network bandwidth! thanks, Stan ---- 1. BTW, Bill, that line count includes the totally unnecessary (and never believable) text: "This email has been checked for viruses by Avast antivirus software. www.avast.com"

Re: Excellent CHM Article on Apple Lisa Software (Apple Archive)

by skogkatt007＠yahoo.com

Companies don't care about history. It does not affect the next quarter's sales. I had serial number 1 of a Radio Shack shortwave receiver and offered it to them. I got a reply back, 'I'm sorry, we no longer support that model.' cheers, Nigel C: wow I didn't even know the Shirt Shack monitored much less replied to customer inquiries via shortwave. I suppose that's 1 way to get patrons to buy your rigs.

HP3000 recently deinstalled available in Colorado for nothing.

by Technoid Mutant

I snipped this from an instant post on facebook, 26Jan2022 at 12:35pm Eastern Standard Time.:: We just de-commissioned our HP3000 minicomputer in December 2022 and are willing to give it away free to anyone willing to pick it up. Photos to follow, but it is the whole system, with 2 green bar printers, manuals et al. Be sure you understand what this is. It is a 1970s era minicomputer that is large and heavy. Sitting on our loading dock inside our building it takes up maybe 10 feet of wall space. This is not a modern "mini computer" like an Intel NUC or Mac Mini... this thing is a BEAST. Priority given to whomever can pick it up first during business hours (8:00am to 5:00pm). Located in Denver, Colorado near I-25 and Colorado Blvd.

68k textbooks

by skogkatt007＠yahoo.com

I have a few scanned somewhere. I always kimd of liked Douglas Halls Microprocessors and Interfacing: Programming and Hardware for 80x86. It's a large format textbook. There is a 68000 version which I don't have. Curious what textbooks other can recommend. As I said I scanned at least 2, maybe 3 some time ago. The Antonakos book seemed to stand out. https://www.amazon.com/68000-Microprocessor-Hardware-Principles-Application…
