The Intertec Superbrain was first sold by Intertec in 1979. It was advertised as an "All in ONE smart portable lightweight console (45 lb [20 kg]): Just add a printer!" The all-in-one console featured a 12-inch screen, 80-key keyboard with numeric keypad, and dual double density 5-inch disk drives. The machine ran the operating system CP/M and was somewhat unusual in that it used dual Z80 CPUs, the second being used as a disk controller.
