   Well I don't remember where I got 25MHz, it's been in my head for at 
least a decade.  But I can tell you for certain that the 78032 on a 
KA630 is clocked at 20MHz, as I've overclocked a couple of them...so 
that would seem to support the idea, as I doubt its successor would 
have a lower clock rate.
