Re: Hardware Diagnostics Tests on a Star Wars board, how does it work?

After reading Marc's post I found 'A New Hope' to get my own board set
fixed, as it also has mathbox errors (divider and matrix). I took all the
notes out there but am stuck at the same spot Marc was. My boardset has
Clay's ESB kit installed; would that give me the unimplemented lights?

Here's what I did: turned on the game, then flipped the switch into
self-test and got the on-screen option display. Then I grounded the DIAGN
and when I ground & release RESET all three lights start blinking. Any ideas
for me?
