Your jumpers seem correct. It looks to me like something is intermittant. Perhaps one of the traces near a jumper got messed up or you're not actually jumpering in the correct hole (some can be tricky) If you want you can remove J7 and jumper from BA10 to J7 (the hole that connects to UC3 pin 1- the rightside one when viewed from the front). Reinstall the UB8 latch. This will remap the odd ram to $8400-87FF ready for ColourPET ;-) I will try to post some closeup pics of the jumpers for 40col so you can compare.
