Nice post from Jason’s blog and a perfect question too: why is 8-bit technology so important these days?
Simply put because it’s where we all come from!
The most common 8-bit CPUs of the time included the Intel 8088 (used in the original IBM PC), the Zilog Z80 (used in many early home computers such as the Tandy TRS-80, Sinclair ZX-81, and Osborne 1), and the MOS 6502 (used in the famous Apple II, Atari 400/800 and VCS, as well as the Commodore PET, VIC-20 and 64). These same CPUs were also used to create the custom computer boards used within nearly all video arcade games.
