Strange.  The ATMega16 I was using was fresh from Digikey but, in my noviceness
I may have cleared the fuse.

But, if the fuse is enabled from the factory doesn't this mean that the JTAG
lines on the PORTC are unavailable until you clear it?  Of course that would
mean that you couldn't use the JTAG to program the chip as received from the
factory.

Oh, well, I'm up and running so no matter :-)

Cheers,
