I have the 82C284 data sheet, which is the CMOS version. I assume it's
very similar.. It's described as 'Clock Generator and Ready Interface for
80286 Porcessors', and I remmeebr it being used in the IBM PC/AT.
Yep, I actually stumbled across the same IC by accident and did find the
datasheet for that one; I'm also assuming that they're compatible. The
They are very close. I can remember debugging an AT clone using that data
sheet, and it was good enough to ensure the machine was clocking correctly.
