Hi
Does anyone have any data books with the specs
and signals for Rockwell's 4 bit processors that
they made during the late 70's? These were in a
funny flat pack called spider chips.

I didn't know Rockwell made any processors like that. But I have a lot
of boards with spider packs on them. Can you list some of the part numbers?

If those are PPS-4s, they were used in some early pinball machines, you might
google for pinball PPS-4, maybe there is a schematic available...

I have a book by Steve Money called "Microprocessor Data Book", and
it lists three Rockwell 4-bit chips, the MM75, MM76 and MM78. They
make up the PPS4/1 Series. Are they the ones you are interested in?

I have a 1984 Rockwell Data Book with lots of ICs in
it - I will need a part number.
