I was given two boards that were "spares for a PDP-11/40." The
business that I got my PDP-11/40 from was cleaning out storage and
found these two boards and gave them to me.
It looks like board 2 is for a Sun 3/50 workstation. Board 1 is some
kind of micro-programmed processor based on AM29331 and AM29331. There
are also some Analog Devices DSPs.
AM29000 based processor with Analog Device DSPs
Sun 3/50 processor
Can anyone identify them?
