Long shot, but does anyone have any documentation or software for the Imlac
PDS-4? I'm working on an Imlac emulator/simulator (for the -1 and -1D) and
I'd like to support the -4 as well, as it appears to add some interesting
options; problem is I'm not finding a lot of detailed information about
what and how it works :).
(Hardware documentation/schematics would also be interesting - I have a set
of what appear to be PDS-4 core memory boards and I'd love to be able to
debug them since they're in rough shape...)
