I recently acquired and restored a rare Tektronix 8002A microprocessor lab. This thing contains no less than 4 microprocessors: Signetics 2650, Motorola 6800, Intel 8080 and Zilog Z80! It can run programs for each one of these processors. Its 8" floppy drives are missing, but the drives of my Signetics TWIN work on this beauty too. It's fully operational, and can program 2704/2708 eproms too.
