Z80 in a surface mount package, as found in the MVS and CD hardware.

The Z80 is an 8bit CPU designed by Zilog.

All NeoGeo systems use it as a coprocessor to handle "tracker music" playback. It only has access to the YM2610, M1 ROM or .Z80 files, and its RAM.

See 68k/Z80 communication.

Since it doesn't share any direct memory zones with the 68k, it can't be used to perform or speed up gameplay-related tasks.

See Z80 memory map.

Z80 in DIP package, as found on AES boards.
