Are you talking instructions per second here?  I'm sure you realize that the
individual 68040 instructions are more powerful than individual 88000
instructions (in general).

I don't what your definition of REAL customers is, but I _know_ that there are
a _lot_ of computer peripherals which use 680x0 processors.  No, they're not
personal computers, but there are a lot of 'em.

Is the CA for content addressable?  I'm not familiar with this term.

And how much will this beauty cost?  You can get some pretty fast ECL chips
right now.  Darned expansive (and power hungry) though!

I'm sorry, but I still don't understand your definition.
