General Information<\/b><\/p>\n<\/td>\n

The PPS-4 is one of only four microprocessors introduced before 1974 (the others being Intel\u2019s 4004 and 8008, and National Semi\u2019s IMP-16). The PPS-4 was the only competitor to Intel 4004. And like the 4004 was originally developed for calculator applications. The PPS-4 chip technology was metal gate versus the 4004\u2019s silicon gate. Although using a slower technology, the PPS-4 implemented a higher degree of parallelism than the Intel 4004. Its performance was comparable to the Intel 4004, according the 4004\u2019s designer Federico Faggin.<\/span><\/span>The original PPS-4, 12660, was introduced in the third quarter of 1972. The PPS-4 had two follow-on versions PPS-4\/2 (third quarter 1975) and PPS-4\/1 (second quarter 1976). Like the 4004, the PPS-4 was used in computing, control and gaming applications. The PPS-4 can be found in several of Gottlieb\u2019s pinball machines.The PPS-4 uses the QUIP (Quad-In-Line) package found in Rockwell\u2019s later 6511. The QUIP package has the alternating leads to reduce package size. While the 4004 was bottlenecked with 16 leads, the PPS-4 had 42.<\/p>\n

“The original part number of the PPS-4 was the 10660. I selected the part number very carefully. The part number appears on every mask layer, but I “accidentally” left the metal off the top of the first zero. Under a microscope the part number looks like “lubb0″ which was as close to getting my name on the chip as possible.” Ray Lubow, 12-17-2002<\/span><\/td>\n<\/tr>\n
