What is the most prized possession in your collection?

by vintagecomputer＠bettercomputing.net

That's a hard one. ?I feel like the answer should be 'my Mark-8 boards!', because they are so rare. ?But they're just boards.. they don't do anything. ?I find the computer I keep coming back to is my Digital Group z80. ?Digital Group just has that personality factor. ?

Microscope for Soldering and Inspection Work

by COURYHOUSE＠aol.com

Be sure your stereo-zoom has a cover thing screwed into the front of it. always good to protect the active optics. We have a rework station with a sliding X Y table on it.... and a scope mounted on it... but... my hands are not steady as when young..( need to find technology to assist with that!)

I use a B&L stereo zoom microscope for inspection, but have never used it for soldering. That is, after soldering in, say, a TQFP, I'll use it to examine for misregistration and solder bridges. But I can't imagine soldering under it. For that, where normal vision doesn't suffice, I use a head-mounted binocular loupe. Seems to work just fine. --Chuck

Anyone have one of these? QDP-300

by jwsmail＠jwsss.com

This looks like a very nice system. I'm not sure I ever heard of it, but today's Sharktank (computerworld) has a fun story about it. Even better extra points if you have the said system in your collection. System (from link in article): http://blog.modernmechanix.com/qdp-300-the-peace-of-mind-computer/ Quasar Data Products http://www.old-computers.com/museum/computer.asp?st=1&c=616 Shark Tank Column, 1/13/2017 (yes Friday the 13th). For future reference if the link fails. http://www.computerworld.com/article/3157097/it-industry/it-its-not-just-a-… The QDP had a hard drive and 8" floppies. Z80 x 64K memory. Thanks Jim

What is the most prized possession in your collection?

by COURYHOUSE＠aol.com

Mine is the HP-2000 ... it was a game changer for me in the used computer business as it gave me a one company direction... from dealing in parts to keep it alive to having HP-3000 systems being an indy new HP dealer on PC products in the 80s into the 90s. On a more personal level, the Classic PDP-8 with the plexi top covers we have here in the SMECC museum project I have given them. I wanted one ion 1965 and finally got one in the 80s!

I recently found a copy > and sent it to the original authors. Oh, wow, neat. Where did you find it, if I may ask - I'm curious! Did a copy go to bitsavers, too (I hope)? Noel

Looking for Dr. Dobb's Developer Library DVD 6

by classiccmp＠crash.com

Greetings all, I always figured I'd order one of the compilations of Dr. Dobb's Journal on CD/DVD One Of These Days... Then they went and stopped publication. While a lot of DDJ content is still online at drdobbs.com, I'd still like to pick up that DVD. So like the Subject says, I'm looking to acquire a copy of this last version of said compilation. Thanks, --Steve.

What's the rarest or most unusual software item do you own?

by jnc＠mercury.lcs.mit.edu

> From: Leif Johansson > Me and peter recently discovered he saved the rest of the box. Is that the one I saw in the 'MIT-MC in Sweden' pictures a while back? > Paul Koning > A listing of RSTS-11 V0 If that's not already online in machine-readable form, we should get it scanned and OCR'd. I have a _very_ soft spot for RSTS-11 - I learned to program on a PDP-11/20 running RSTS-11. (Actually, I learned to program from reading a BASIC-PLUS language manual, borrowed from Matthew Weinstein, over my first weekend at boarding school!) Being able to run on it an actual PDP-11 (using Guy's MEM-11 card) would be so far beyond super-cool that it would be below absolute zero... Noel

OT: Germany: Looking for transport opportunity Cologne -> VCFe or Nuremberg or Offenburg

by Arno_1983＠gmx.de

Hello dear listmembers, sorry for the off-topic request. I have a chance to get two beautiful optomechanical Mettler lab scales from a gentleman in Cologne for a very nice price, but the seller states outright that he won't ship them (which probably wouldn't end nicely for the goods anyway!). So I'm looking for someone able to collect those (approx. 20*40*40cm and <10kg each) in Cologne sometime soonish (payment would be effected independently by bank transfer, there is one externally accessible transport safety screw on each device which would have to be checked/tightened) and deliver (timing for this step is largely uncritical) to either my home near Nuremberg BY, hand them over at VCFe in Munich BY on April 29th to May 1st, or meet me at a field day near Offenburg BW on April 7th to 9th (additional opportunities may appear). Compensation for fuel and time will be paid, please enclose your asking amount. Thanks in advance, yours sincerely Arno Kletzander // DO 4 NAK

Unknown 8085 opcodes

by shadoooo＠gmail.com

Hello Adrian, not sure if 8085 is supported, but try to analyze your dump with IDA Disassembler. It's really amazing in analyzing the code, and reconstruct automatically, or with small effort, a readable trace of functions jumps, strings, symbols, etc Andrea
