Still more Parts available: DEC, TI-990, and HP1000

by pfriedr＠gainbroadband.com

I've just added to yesterday's list of vintage computer items that need to find a good home. Details, part numbers, and descriptions can be found here: http://www.hpfriedrichs.com/hpfparts/hpfparts.htm Thank you to several classiccmp members who corrected my earlier post. Some of the parts I have listed are associated with PDP 11/23s, not 11/34s. 73 Pete AC7ZL

Analog to Digital Converter

by dj.taylor4＠comcast.net

I have a number of laboratory instruments that are from the 1990 time frame. They produce digital data that is the digitized signal from a detector, the data can be from 512 to 65K samples long. The ADC used in these instruments is a 16bit 100ksample/sec design. The ADC is in a 3 by 4 inch metal box with a row of pins on each long edge. I think some of them are failing because I get the full 16 bit resolution from one machine, but not the others. This was determined by taking the digital samples and sorting the values and computing the increments between the adjacent values. In some cases the output looked like 14 bit resolution and in one case 6 bit resolution. Does anyone have any experience with this ADC technology? Who was the manufacturer? (There is no id on the outside) What is inside the box? Is it a hybrid circuit? Doug

Booting an IBM MP 3000 S/390 System

by ggs＠shiresoft.com

I spent some time today and made a video of my MP 3000 system booting up to z/OS. The video is here: http://youtu.be/WnJmeQR0GQU. Even though the video is about 9-1/2 minutes long, it takes longer than that to boot. I edited out some of the more boring bits. ;-) TTFN - Guy

SCSI Tape to TAP utility

by marc.verdiell＠gmail.com

Well, Chuck, thanks a bunch, this is very useful and quite difficult code to write from scratch. How does one compile for DOS by the way (I have to admit I am too young to have ever tried), and get a copy of MSC 8.00C. Is the DOS compiler buried in some part of Visual Studio? I have some old versions dating back from Windows 95 time, when it was called Visual Studio 97...

A series 42 would be nice, but a series 37 or micro XE would do. Any leads? I'm already aware of the one on Epay in Florida that's been sitting at $1,725 for the past year. I'm in central PA.

8-E(s) in Illinois

by useddec＠gmail.com

While pulling parts for another list member my workers found another 8-E. I thought I had 2 in the area, but who knows. Anyway, if you are going to Chicago (VCF) I'm almost 3 hours south of there, but I have several list members who plan on stopping by before or after and might be willing to deliver or get it closer for the right price. I had already planned on selling one, so now I actually have 2. Both are 8-E boxes, H724(I think) power supply, a single omnibus backplane, a switch panel, silkscreen, one has white bezel. They do not have :keys, cover (or lid), slides. I can configure the boards to anything within reason, but I suggest you go with the mos board or kit available on the list. Core is getting expensive. Please contact me off list with questions. Thanks, Paul
