− | + | The '''Rockwell PPS-4/2''' ('''PPS-4/2''') was a 4-bit [[microprocessor]] designed by [[Rockwell International]].

− | + | == System == | |
− | + | Similarly to the [[Intel 4004]], the Rockwell PPS-4 required two additional support chips: a [[clock generator]] and [[ROM]] memory. The chip came in a 42-pin [[QIP]] package. 12 I/O terminals are available for general purpose I/O. | |
