The schematic is dated 1975, the manuals 1976. I purchased it in 1979 for $245.00, power supply not included. It has an 8 bit processor with a 16 bit address bus. The hex keypad allows input of 8 bit machine codes and the hex LED displays the 16 bit memory address and 8 bit output. The program I wrote required more than the standard 1024 byte memory so I wired an additional 1024 bytes (lower right).
