PRINTOS MARSH CPU II+ operating instructions

by brain＠jbrain.com

Someone gave me a copied copy of the PRINTOS MARSH CPU II+ Operating Instructions. I have scanned it to PDF. I do not want or need it here. So, I am happy to ship the hardcopy to someone for cost of shipping. I am happy to provide the PDF to someone who can archive it.

ADM 3 OR 3A NOT SURE AVAILIABLE

by RLAAG＠pacbell.net

I HAVE AN ADM 3 OR 3A, NOT SURE WHICH, I THINK THAT I DON'T NEED... WHEN I USED IT YEARS AGO IT HAD SOME HORIZONTAL PULLING BUT MORE OR LESS WORKED THEN... NOW I DON'T KNOW BUT DIDN'T WANT TO TEST IT OUT... THE SCREEN HAS SOME STRANGE SPOTS APPEARING BUT THEY MIGHT BE JUST ON THE SURFACE OR MIGHT BE INSIDE LIKE THE OTHER POSTS ON HERE ABOUT THAT... I DON'T KNOW, BUT MIGHT BE GOOD FOR PARTS ANYWAY... CAN LET THIS GO FOR SHIPPING AND A LITTLE POCKET CHANGE...

Anyone have specs (voltage, polarity, etc.) for the Radio Shack 270-1551 power pack? I want to test out an old tabletop computer game, and do not want to invest in six C cells. -- Will

Looking for a Zenith Z29 terminal, and some VT100 keyboards

by ian_primus＠yahoo.com

Well, I just acquired some VT100's, albiet without keyboards. So, now I'm looking for some VT100 keyboards - even broken or damaged ones. Also, I _just_ missed a Zenith Z29 terminal (newer than the Z19, with detachable keyboard), on eBay, simply because I forgot to bid before I left the house. Augh! So, I'm looking for one of those too - does anyone have one that is looking for a home? Also, while I'm looking for stuff, anyone have a Qbus Pertec tape drive controller that'll work in a Vax? Thanks guys! -Ian

MOD8/80 hardware?

by sellam＠vintagetech.com

I'm passing along this request from Zbigniew Stachniak, a regualr VCF speaker and Associate Professor at York University in Toronto who also does a lot of excellent computer history research. He's looking for Microsystems International MOD8 and MOD80 hardware for some current research (see below). If you can help him, please contact him directly. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ] ---------- Forwarded message ---------- Date: Tue, 06 Nov 2007 11:22:44 -0500 From: Zbigniew Stachniak <zbigniew at cse.yorku.ca> To: Sellam Ismail <sellam at vintagetech.com> Subject: Re: VCF 10.0 Sellam, It was so nice to be able to attend VCF again. It was a great event, I have met a number of interesting people -- thanks. I have briefly mentioned to you my search for Microsystems International Ltd. (MIL) MOD8 and MOD80 hardware. These are little blue boards that plugged into a backplane which is depicted on our museum's page http://www.cse.yorku.ca/museum/v_tour/artifacts/artifacts.htm The MOD8 and MOD80 hardware (as well as the MONITOR8 software and MIL cassette interface) were reasonably popular among the hobbyists in the mid 1970s. I'm looking for the MOD8/80 boards not only to supplement our museum's MIL collection but also because I need them for my current research. If you could help in finding some of these MOD8/80 boards it would be great.

What is a safe way to clean corrosion?

(You want to neutralize the affected area as well as possible.) Then take a hair dryer and gently dry the area. I recently found a discarded power supply that was so coated with oily, nasty, soot-like "stuff," that I decided to experiment. I disassembled everything and got my special green soap used for cleaning aircraft interiors and a brush. It worked wonders. I then rinsed the whole pcb (with components) and blew it off with compressed air. Then I dried it with a heat gun (very carefully, as this heat gun could easily ruin everything). I allowed the pcb sit for a few hours, then put it all back together and fired it up without incident. Caution: "Your mileage may vary..." Regards, Robert Greenstreet

know where I can get a 800k drive for a mac SE?

Could it be mid-life crisis? Instead of buying sports cars, we're looking for the computer configurations we longed for but couldn't afford in our youths? Although, I must say, my head has been turned by the prospect of MythTV running on a shiny *new* collection of hardware. I'm seriously considering decimating my collection of old Macs and just focusing my attention on playing around with modern stuff for a few years. Of course, I want to perfect replacing the FBGA soldered memory chips in the Apple TV and use hacked ATVs as the MythTV front ends. If there's no hardware hacking, where's the fun? Jeff Walther
