Hi,
I got an PDP11 board, labeled BSB11 from ROI.
There are some diag LEDsi for Power and some BUS Signals,
something that looks like an connector for an front paneel,
an hughe field of soldering points for placing own circuits,
an 5.0688Mhz Crytal oscillator, an GAL, and some 74xx ICs on board.
Does someone know what that circuity on the board should do?
Regards,
Holm

Don't see any wires going to the bus on the top.
Picture of the solder side?
But probably it is a bus analyzer of some sort.

Bus analyzer or possibly a prototyping card with some built in functionality?

Yes, for sure since there are some BUS signals near the LEDs printed on the
PCB. But to what they need a crystal OSC?
I make more pics tomorrow.
