I would like to thank all the people who responded to
my question about the "sonata" I heard when turning on
my MacII. I was informed of a freeware program that
plays the different tunes and tells you what they mean.
I was also told that the problem could likely have been
to the SIMMs not being seated properly or having some
corrosion.
Thanks again for the help. You know who you are!

I have a Mac II that suddenly doesn't respond to the mouse or keyboard. (ADB ports seem to be screwed up). I tried different mice and keyboards and also switched ADB input ports on the back of the machine, no luck. I called an Apple repair place and explained the problem. The person said that the "logic board is fried" and I need an entire new one (quote ~$400) Is there another way out of this? The solution seems a little overkill. Thanks for any help, Dave Francis - Sapphire Design Systems

If you have plugged/unplugged any of the ADB devices while the machine is on, you may have blown a fuse on the motherboard. To my knowledge, it is soldered on the motherboard, so it requires a board swap. You could try attaching the keyboard and/or mouse to another system for verification, or try attaching a different keyboard using a different cable... -- ----------------------------------------------------------------------------- | Glenn L.
