Joe:

	Thanks. I had a momentary short in the power supply line when I was moving
the board around during some testing. Could be anything. That's why I was
trying to decode what appears to be a diagnostic code on the screen before I
start replacing things. It's probably NOT the CPU or the ROM only because
I'm actually getting screen output. I'm guessing one of the 74xx chips or
the DRAM.

  Major bummer!  I don;t have a source listing but I do have a couple of
working SB-180s. I can dump the EPROMs for you if need be.
