- One implication of all this is that in future designs memory may
- provide a data available signal, and be variable speed. This is an
- interesting concept, and somewhat reminds me of the AT bus with a "0ws"
- line to indicate zero wait state memory. I could envision all memory
- being 0ws, with a latch logic something like "if dav not active on next
- clock raise wait and hold until dav."
-
- Of course the "wait" would be the bus interface unit, and not the CPU
- itself, hopefully. Not too different from what we have in some systems
- today, except the wait would originate on the memory chip rather than
- the support logic.

- It never ceases to amaze me that otherwise rational people, able to
- understand calculus, compound interest, and the income tax form, can
- continue to believe that poker is a game of chance.
