Wanted: PERQ 3 photographs and logic diagrams

[It's me]

Hi,

For the Perq 3 I am trying to find:
a) close up photographs of the boards, to enable device types to be read.
b) logic diagrams / schematics.
c) I am most interested in the CPU board.

Any help gratefully received.

Regards

There are a few known PERQ 3A systems around the world, so photos may someday be attainable if the owners were willing to do the disassembly and photograph the components. There are only a few tantalizing pieces of a PERQ 3B system (so far all I've ever seen is a memory board from a prototype unit) and absolutely zero photos of any systems derived from it, notably the Crosfield 9500 photo-typesetting workstation. I, too, would be thrilled to see any PERQ 3 photos, since they're a LOT more interesting than I'd ever suspected - far more than "just another 68k workstation" from the mid-'80s...

Archives of some of this have been found! Whether or not the media can still be read is another story; 8" floppies have held up well, but QIC tapes have not aged well at all...

Indeed! :-)
