Sharp X68000 Pro (CZ-652) IC List

This is an old revision of the document!

This is a list of all the discrete logic components on the X68000 Pro (CZ-652) motherboards. I have not included:

ROM/RAM devices
Microprocessors
Custom Sharp IC's

This is just the standard, off-the-shelf, 74 or 75-series logic chips that could be replaced fairly easily.
