===== X68000 Generic Chips =====
It also featured a wealth of off-the-shelf chips from a variety of manufacturers.  The X68000's Okidata ADPCM sound chip was also used in at least one other game console, and Yamaha was essentially the only soundchip manufacturer of any import back in the day.   Chips from Zilog, Motorola, Hitachi and NEC all made their way inside.   As was the norm back then every chip that had extra pins was put into service for another device. The printer controller also handled joystick input, the serial controller handled the mouse and the MFP had its fingers in nearly every input or output port available.
