Documation card readers for sale

[Curious Marc]

Interested in the Arduino interface too. Will save me some time. Has it been posted anywhere?

I'm interested in that!  I was designing one in my head this weekend.

Much better to stand on the shoulders of giants!

 

I'm also working on getting a cable made to hook up to the M843 CR8-E

punched card reader interface for the PDP-8/E, but that's a project for

another day (year?).

 

I have an M8291 CR-11 board (untested) but no cable.  Same cable as

the M843 AFAIK (documented as such).

 

The interesting thing about my M-200 is it has a factory mod - a

6802-based parallel-serial board, mounted on an internal 44-pin

0.156"-spacing connector, so rather than remove that and use an

external cable, I have the option of making my own card for the socket

with a 40-pin Berg connector and using a straight 40-pin cable to the

M8291 or M843.

 

But since mine is punched-cards only (not mark-sense cards), I'm not

that likely to punch a lot of card decks for mine.  Once I read 3-4

decks for a local buddy, I don't really have "next use" for my reader.
