Looking for old data information - test-drb@ccmp.vtda.org

2 Aug 2004

Hi Steven
 I suspect that the MM78 is at least one of the
parts that I'm looking for. I regret that the
actual chips have no information on them other than
the date code and the in-house part number. There
are no generic part numbers on their labels.

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

Steve.

  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 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?
