Wow! I did not anticipare such a wonder ful response. Thank you very much
all.

I will take *all* of your advice actually - I will use the 74AC192 for the
divide-by-N counters and try my hand at PLD's for the PLL and peripheral
circuitry.

I run Linux and can program Perl blindfolded, so writing a programmer will
be no problem :-)

Again, many, many thanks!
