So Robowar has conked out.
Midway through a ball, I got a few loud beeps, the display disappeared and it reset. Since doing that, it won't boot. Sometimes the soundcard LED comes on, sometimes it doesn't. I did get it to boot once (nothing I did would have fixed it), but then the same beep/reset thing occurred second ball.
Not much experience with fixing 80Bs (or any architecture for that matter!) so bear with me.
Things I've tried:
* Checked all transformer fuse continuity
* Reseated all connectors
* Pushing on the daughter board to check cracked joints
* Closing slam switch, although it looks as though the slam switch mod has already been done (solder bridge)
* 5V power, both on the 5V supply and after the first capacitor on the MPU next to J1 (5.33V)
* Checked connector terminals at J1, a few were broken so I repaired those, but it didn't fix
* Checked interconnect cable ground mod, had been done already
* Checked transformer ground mods, not sure about these might need to confirm
* Checked for hot chips, nothing jumping out
Anyone used a QuickScan80 before? Or have one they'd like to sell me??
Failing that anything else I should be checking?
