Hello all,

I don't think I explained the ROM SIMM situation this very well in my first post!

My IIfx works fine but when I use its ROM SIMM in the IIci it chimes normally, then it plays the chimes of death.

With the SE/30, which still suffers from 'Simasimac' after a recap and replacement Bourns filter, ROM SIMM the IIci will give the chimes of death.

I'll keep testing the traces and vias of the ROM (HH) to make sure continuity is OK. When I removed the oscillator to check underneath it the traces looked fine.

Thank you!
