I'm going to try that 4th link software that Zoot posted.  It's also at the SXList site, just for future reference:

I really am using 4700 ohm resistors with the LED's.  I can still see them just fine for testing purposes, and I know I'm way under the current maximum, even without having to do a calculation.

I have an older 9-pin D-sub connector style SX-Key, that says, "Revision F" on it.  I've run many programs on it without any problems.  I've pulled the oscillator out, so that can't be the problem.

Still, the program seems to be doing something when I use the I2C example in the "Programming the SX Microcontroller" book.  I was hoping someone would find a line out of place.

BTW... in the i2cs.src program, he allows you to choose whichever two port pins you want.  But... isn't the SX hardware set up so that only PortB can trigger interrupts?  So wouldn't that mean that I can't use PortA?

Anyway, thanks for the tips and advice, please keep them coming.  I'll post in this thread after I run the i2cs.src  program.
