Processor Technology Corporation was a microcomputer company founded by Bob Marsh and Gary Ingram in April 1975. Its best known product is the Sol-20 computer. Bob Marsh, Lee Felsenstein and Gordon French started designing the Sol-20 between April and July of 1975. The Sol-20 utilized the Intel 8080 8-bit microprocessor chip, running at 2 MHz. A major difference between the Sol-20 and most other machines of the era was its built-in video driver, which allowed it to be attached to a composite monitor for display. The Sol-20 consisted of a main motherboard (PCB) mounted at the bottom of the case, and a five slot S-100 bus card cage. The main PCB consisted of the CPU, memory, video display, I/O circuits. Inside the case included power supply, fan, and keyboard. The sides of case are solid oiled walnut wood, and blue painted steel.
