The second board is clearly out of a ComputerVision CADDstation.

It is labelled as a sun 3-60  270-1205-04

   I said 3/50 because that is what the silkscreen says.

The silkscreen clearly says 3/60, you have a clear serial with a 5
right beside it to compare and any other marked component.

   I know nothing about Sun hardware.

But an expert on Some Online schematics? :-)

I said 3/50 because that is what the silkscreen says. I found some
picture online and the 3/50 was a different layout. It sure looks like
a 3/60


The silkscreen reads "3/60" as clear as day...



Looking at some online schematics it looks like the P3 96 pin DIN
connector may only be for power. Is it possible to power this thing
through that connector without a proper chassis?


Don't see why not.  You'll need to rig up the proper connection with 
some eurocard connectors, and provide a decent supply (I can't find any 
solid info, but I'd wager between 5 and 10A for +5v).

In the bottom right hand corner, above ³COMPONENT SIDE², there is some
lettering that seems to read ³COMPUTER Š BEDFORD MA². Given the DSP¹s, the
MITRE corporation comes to mind. This might have been part of some
military or civil aviation signal processing system.

I think this is a 3/60 processor. Not 3/50.

Sun 3/50 processor board and unknown processor

[Charles Dickman via cctalk]

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.
