An 8-bit microprocessor released by Zilog in 1976. It powered many home computers and arcade machines, as well as the hardware Zgrass ran on.
Tom DeFanti at EVL took that machine, added memory and a keyboard, and ported his GRASS language from the PDP-11 to create Zgrass, named for its Z80 processor.
