These two "modules" used a common processor and memory so they can be described together. The microprocessor was a 12-bit central processing unit manufactured by Toshiba, the TLCS-12, which began development in 1971 and was completed in 1973. It was a 32 mm² chip with about 2,800 silicon gates, manufactured on a 6 µm process. The system's semiconductor memory included 512-bit RAM, 2 kb ROM and 2 kb EPROM. The system began production in 1974, and went into mass production in 1975.[1][2]
Ford's internal code name for the TLCS-12 microprocessor was "PM-11" or "Poor Man's 11" implying it was a stripped down version of the, then popular, Digital Equipment Corporation PDP-11 computer. A PDP-11 was used in a vehicle in the first half of the 1970s for "proof of concept". In reality, there was very little in common between these two computer architectures. This chip was never commercially available.
