Nah, not even close. In the unit I mentioned

32KHz. (no typo there)
I don't see that being able to handle talking to a PC keyboard,
though.
Yeah we might have to bump the clock rate up to a screaming
1MHz. ;) (I personally have done it at 4MHz with lots of cycles to
spare)

At this late
date it would probably be easier to design
and build an interface so that a common PS/2-type keyboard
could be used, along with some self-adhesive key-top stickers.
Seems like overkill - the interface would need more processor
power than the ZX81, most likely.
