Hello:

After the tips from the ppl at these forums, I washed the motherboard and the computers works! I been able to boot and enter the Os without problems, everything is working even the programs (I believe the computer was last used around 1999).

Anyway, I have two further problems:

1.- High pitch noise: as I understand is a symptom for bad caps. I have worked around this problem installing a plug in the audio out of the mac. It eventually stops after 5 minutes of continuos use of the Mac. Any advice for a long term solution (other than recapping)?

2.- The system is not recognizing the installed memory (2x1mb simms). These simms have been tested in a SE/30. Any tips as to installing the memory or other hidden issue that could be causing problems with the RAM?

Many thanks to every1
