AVR-Chat

This worked. Now I need to figure out why it happened to prevent it from
happening again. I have to go now but want o run some ideas by you when
I get back.

No.  If you just set your second board to toggle the I/O pin as fast as
it can, then that will probably be fine.

Yep.

Yes - it shouldn't be hard.

Regarding a series resistor - you shouldn't need one.

If you can't recover your fuse settings, you can send the board back to
me and I'll take a crack at it.  Worst case, I replace your ATmega128.
