I pulled this board out of a bin of processed PCB's so it seems that the EPROMs and possibly a CPU is absent.


Trying to specifically get additional information about what exactly it's doing and where I might get those IC's replaced, or if I should bother with the board at all. Research indicates that the board was manufactured by Scientific Micro Systems for the FWT0100 and FWT1100 combination floppy/hard disk cabinet for the PDP-11. The cabinet emulated an RX02 and had a qbus interface. It's pretty obvious that the 50 pin header connected to the drive however I cannot tell exactly what the rest of the headers do as the wiring diagram in the manual ( https://archive.org/details/bitsaver...lJul83_7644764 ) is cut off because someone didn't fully scan it.
