The PPS-4/1 is the third iteration of the {{rockwell|PPS-4|original PPS-4}}. The PPS-4/1 were architecturally identical to the {{rockwell|PPS-4}} and {{rockwell|PPS-4/2}} with the addition of a [[clock generator]] and [[program memory]] incorporated internally, making it a single-chip system (hence the "/1").
