Richard,

I see your point, but to me the 68K is an old obsolete CPU, thats well due
for retirement.

16MIPs is enough for most apps, agreed sometimes you need more.
My biggest bugbare is that the newer CPUs are all SMD, which means no
prototypeing onto vero (yeah, I know you can get adapters but that costs),
so you have to design a PCB and get it made, before you can start
prototyping a design.

last time I checked (a year ago) around $70 each, so not bad for what you're
getting.
But if all you need is a micro to drive your DAC and S&H, the a £5 AVR will
do the job with ease :-)

Hehehe, NEVER, until they can guarantee delivery at a set time!
but, thats a whole different argument.
