Does anyone know what this board would go to? It's a California Data
Processors board, ca. 1978.

It was found packaged in a Data 100 Corporation cardboard box, but I am not
convinced it really belongs in there.
Thanks,
Kyle

The shape, size and edge connector style match a hex-height Unibus card
for a PDP-11, and a quick look at the edge connectors shows bus grant
jumpering where I'd expect it, and what look like poer and ground
connections seem to match too. So I believe it's for a Unibus PDP-11.

CalData made a PDP-11 emulator, totally unauthorized by DEC. A mediocre
machine, but relatively affordable. We had a few of them at Washington
University in St. Louis. DEC people would get hysterical when they saw
it, and start backpedaling out of the room!

It is for a Cal-Data PDP-11 clone.

Wonderful! Looking at page 24 in this PDF (
http://bitsavers.trailing-edge.com/pdf/calData/CalData_Brochures_1974.pdf),
I guess it's safe to assume that I can in fact put it in a DEC-brand Unibus
as well? That'd be quite nice.
