DEC 8640 Pinout

8640 looks like a date code; most dec chip numbers begin with "DC".

    I am trying to trace the reason why the CPU on my Pro 350 is apparently
    being constantly reset. I have reached a DEC 8640 chip. Does anyone have a
    pinout for it, perhaps even a datasheet, so I can understand what it is
    supposed to do and whether the pin is an input or an output?
