Digital Group, The

The Digital Group was the first company to produce a system built around the Zilog Z80 processor. Their hobbyist-targeted products were based on a system of interchangeable boards and components which allowed users to upgrade to different CPUs without having to replace their peripherals. Their products included the MOS 6502 and Motorola 6800 processors. They were established circa 1975 and went into bankruptcy liquidation in late 1979.
