Ah yes, I stand corrected.  According to Wikipedia, the affected CPUs
were all the 2106x CPUs (EV4, EV45, LCA4, LCA45) plus the 21164 with no
suffix (EV5).  However, we're still talking about museum pieces here.

I wonder what the one I have in my garage is... I'm sure I could emulate
it faster, though.
