I have a Sega Scud Race upright single player.
The machine comes on but after about 90 seconds while in attract mode the following message appears.
Error (03) Data access exception.
LR : 00000308
SRRO : 0002c048
The machine now locks up.
During the short period before this happens i can enter test. The ROM test checks all Good .
Any suggestions or ideas of what might be the problem would be appreciated.
Thanks Jim
