That's fair enough, it was a very subjective opinion, my previous
experience is mainly in "critical systems" work. Perhaps it is not as
relevant as I first thought.

...yes, this was the bit I was suggesting could be optimised!?

...ccooowelll, is the full info online anywhere? For a start "how
much?" <:-)))
Again, my 'newbie' apologies, I was unaware that you could upgrade the DSP
in these little babies

One is left only to presume that assembler was not his strong point ;)
