Default PDP11 Unibus boards.

This pair turned up in a box of assorted ham 'junk' recently, I thought they might bring some memories back for those who may have used these computers. The Unibus termination board (M9302) is clearly marked PDP-11/04 or /34.
The minimum load module (M7556) is reffered to on the 'net as being for /84 systems.

I would imagine there are still a fair few of these around in use?

Amazingly enough, I believe that one of our members has a PDP11 of some sort.

I had many years of paid fun programming PDP-11s in the power industry. There may be some left, especially in nuclear sites - the paperwork for changing something means that equipment has a longer working life than in a conventional power station.

All I have left now is a few manuals. I think I have some instruction set reminder cards and a KDJ-11 (i.e. 11/73, 11/83) processor manual.
