Like the title says, I'm trying to debug a Gauntlet board I picked up and am wondering if the slapstic has died on it. All it does is gives me about a quarter screen of garbage, then reboots. If I disable the watchdog, it will stop rebooting but does not display anything.

I thought that you could at least boot a Gauntlet board without a slapstic, but I wasn't sure. Anybody know if this is true or if there are any other issues that might cause this? All the voltages seem good at the molex on the board. Well, the +15 was a bit high, but that should only be used for sound so no biggie there.
