Hi guys,

I'm very new to looking at Paperboy PCB's. I've recently setup a power brick and AR3 on a test bench, and have the correct voltages going to the PCB, although the -15v is a bit low at -14. something volts, but I think this should be good enough

Anyway the PCB is watchdogging. I think I've previously checked the ram and the roms as they are socketed, and they were ok

Any ideas where I should look next?
