Hey, my rifa caps haven't exploded yet, either! :-D

See reply to Glen, though - I'm getting an alternating F-9 on the hex 
display / CPU diag LEDs, which the docs don't mention as being a 'thing'; 
they seem to imply that startup codes should decrease from 'F' and stop if 
there's a fault, not go into a condition where they alternate.
