The Z80 is an 8bit CPU designed by Zilog.
All NeoGeo systems use it to handle "tracker music" playback. It runs at 4MHz and only has access to the YM2610, M1 ROM, Z80 files, and its RAM.
Since it doesn't share any memory area with the 68k CPU as on the Sega Genesis, it can't be used efficiently to perform gameplay-related tasks.
See Z80 memory map and Z80 port map.
