Monster Bash
Williams, 1998Just installed the board. Currently updating MB with the PinSound board (with USB). Their soothing elevator music is playing, and British chick is talking to me every few minutes "50% complete!" 
Looks like the entire update will take about 45m to 1 hr.
Is the DMD supposed to be blank during this? I see a few flickers and bars here and there, but mostly blank.
Guess I can wait to check out all my cables afterward.
Well, it updated and finished (apparently). But no video. Intermittent flashes on the DMD is all I saw.
Apparently the data cables were backwards... pin 1 (red stripe) was connected properly to both ends, but the cable needed to be installed the other way.
Everything looks fine now. Now I have to tune the sound so that it's not so bassy.
For anyone in the future who sees DMD problems... switch your cables around the other way (switch ends).
