Good advice. The situation is the same with the extensions off. Freezes anywhere from instantly to a minute later. Arg!
If the PowerCache is broken, and I look into tweaking it - anybody know what was different between the 33MHz and 50 MHz versions? Is it as simple as replacing the crystal, CPU, etc with faster rated parts? I wouldn't do it right away, but if something is fried on the board I might eventually just pull the parts off and repopulate it to see what happens
