Microprocessors - The Early MPUs, Part 2 - PPS-4, F8, 8008, 6100, 6701, IMP-00A, 2650

About this Artwork This collection contains some of the earliest, and perhaps more esoteric, microprocessors. These designs are among the very first microprocessors, but when compared with the Intel 4004, MOS 6502, or Zilog Z80, they are relatively obscure. Many of these were the first microprocessors for their respective companies and, in fact, played important roles in the development of the microprocessor industry. The design variation of these devices is amazing. All developed in the 1970s, some were 4-bit, others 8-bit, one even 12-bit. They used TTL, PMOS, NMOS, and CMOS technologies. Whether the job was to run mini-computer software or control a pinball machine, early microprocessor designers were free to decide what their microprocessor would look like and act like. They could focus on its function.The internal architecture of these microprocessors is quite varied. The 6100 was designed as a DEC mini-computer on a chip. The 8-bit F8 and 2650 were good at realtime control and po
