Is there supposed to be a ROM at U1 on the MPU? I read in Google about
how if there is a 32k ROM at U2, there doesn't need to be a ROM at U1. I
recently installed a 6810 RAM at U7 that originally was missing, so
maybe U1 is missing too? Or does there need to be a jumper set
somewhere? The LED before the 6810 replacement flickered then flashed
once, now it flickers and doesn't flash, and according to my manual,
it's a problem with the memory bank and to replace U1-6, 7 and 8 one at
a time. I would appreciate any help.
Thanks,
Matt
