Documation M200, M600, M1000 card reader, circuit boards

Most recent revision date of this page, Apr 20 2021.

I acquired in 2014, several sets of small Documation M200 series card reader cards. They may also fit M600L and M1000L readers. This page describes them; contact me for more information and to order cards. If you want to duplicate cards you have, send photos of your cards and PC board numbers on the back; I will charge more to try to duplicate your cards as best I can. In 2016, it's time to move these or scrap these - but for my fuss I want more than scrap prices of course. Three boards weigh just under a pound, 10 close to 3 pounds. I want $10 a board for a few, several dollars for many, and some $$$ if I have to provide very specific match-your-photo boards. Shipping is extra.

I offer a variety of vintage computer circuit board cards. My "contact me" Web page describes my terms and ordering details. - Herb Johnson

Documation series circuit boards

On the Web

The Documation M200 tech manual is online at bitsavers.org. The manual shows a rack of six cards, boards number 1, 2, 4, 6 on the board extractor clips. Drawing numbers are 10407XX series.

The 1040353 sync card looks like board #3; 1040765 clock card looks like board #1 (#4?); 1040619 control card looks like board #6; 1040610B error card looks SIMILAR to board #2.

cards I have

The cards appear to be for the Documation M200, M600 or M1000 series of "tabletop" punch card readers. These cards have TTL chips from the late 1970's. Small boards with two edge connectors, many tagged as nonworking. They are numbered 1-6 on extractor clips. There's an assembly or PC board number etched (in solder) on board, and usually some kind of part number too. The PC board numbers seem to follow a 104XXXX, or 164XXXX, or 124XXXX - maybe those are model 1000, 600, 200 boards - my guess?

Here is a sample set.

carddoc_2.jpg 2 - 305658
carddoc_3.jpg 3 - 1640944
carddoc_4.jpg 4 - 104?799D - looks similar to #1

Here's a set of boards I have on hand, of the sort that might be from one reader.

Here's another of boards I have on hand, of the sort that might be from one reader.

An extender card. As of April 2021 I have TWO - The one with undamaged connectors has been sold. here's the other side. The second has both card connectors but has some damage to one, which may be repairable. The third has no card connectors but I have one loose to solder in: this board doesn't have gold-plated fingers, they look like "ENIG" (look it up under PC boards) and so much less shiny. People ask me about buying one of these and then choke on the price. Don't expect to buy them for $10-$20.

Here's a photo of all three. In April 2021 I've bought more edge-connectors to repair these cards. Contact me if you need card-edge connectors. 2 X 18 pins about 2-3/4 inches long across the connector pins - and DEEP, 3/10 inch. TRW 253 18 00 254.
