Sun 3/50 processor board and unknown processor

[Charles Dickman]

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.

Can anyone identify them?
