I heard a few years ago that there are some pin for pin replacements
for 765 chips. Actually many 765 controller chips have some pinouts.
If I remenber right, the newer controllers need higher clock rates
that those old, so you may have to also change some other componets
as well. You have to check it yourself, I am not sure about that.
