Silent IIci

...maybe there's something more inherently difficult with the SE/30.

Perhaps the traces are somewhat more fragile, either due to construction techniques or old age (ore a combination thereof). Also, with the way the capacitors leak on the poor things, the electrolyte seems to get right underneath the traces in no time at all. I don't know if it's the way they're built or what.

FWIW, other than one IIsi board, the only losses I've had are SE/30 boards. In addition to the capacitors, you have to worry about failed Bournes filters also.
