I have a PCP-11E board, which I'd like people to comment on, perhaps point me at some documentation if you know of any. Google is saturated with references for the three letter acronym for a controlled substance, nothing much has showed up, and the manufacturer was not very proud of the board, so that won't reduce ambiguity in searching for info. It has a z80, and a couple of Parallel I/O chips as well as a Zilog CTC on it, so it is smelling like some sort of equipment interface or perhaps a Laser printer or high speed printer board. Probably has a 2716 chip on it for code, would like to get it imaged and disassembled. http://jimsoldtoys.blogspot.com/2016/02/pcp11e-qbus-board.html I did a quick look at the thing and there are pictures of the overall board as well as closeups. I guess one could hope to play with CPM on it if nothing else. thanks Jim
