This is a VAX11 programming card. It is not really a card, it's a 10 page booklet. It is a complete list of the instruction set, and registers for assembly language programming of the 32 bit VAX11 mini computers. I used it a lot, (wrote a tic-tac-toe program for the VT100 in assembly code once), as an example of the CASEL command....
I was a DEC Field Service Engineer during the 80s and 90s. This is one of the pocket cards that I carried in my briefcase. It has seen some use, I wrote lots of notes in it, but the pages are still all there, and in very good condition. You can own a piece of computing history, and write your own VAX machine language code with this card. You might have to look around a bit to find a machine that will run it...
I was a VAX specialist (worked in the SV and NI factories in the 80s and then in the field) and have programming guides, service cards, schematics, and other souvenirs from that era. See my other auctions for more of the same.
This item will be packed in cardboard, and shipped in a trackable flat rate envelope. I ship within the united states. Happy Bidding.
