Ok, tried all combinations of "STK500 Osc" and "ISP Freq" settings and still 
no hint of a suggestion that the M168 wants to talk.

I've checked that miso, mosi, sck all have impedances to 0/5V in MOhm range, 
and reset-to-5V just under 10k (these values are the same on the older M8 
board that does work with STK). Are there any other conditions that I ought 
to check for? Should I try removing the external xtal?

Thanks,
Mark
