Ah - mine is Rev B01 and is without this Table 1.
The only mention about 21066A is as "future DECchip 21066/21068
processor upgrades"
Interesting about your version is that they also mention a 21068A.
Wonder what's different between 21066 and 21068 beside the clock
frequency that they gave them a different number.
Considered that it made it into A revision there must have been a
market for it.
