( _DDN[INFO-APPLE@BRL.ARPA] ) Subject: Interrupts and Reboots on II+ For: Lyman Hurd Re: Interrupts and reboots on II+ I had a similar problem with a II+ a few years ago. The power supply turned out to be very sensitive to voltage dips, and the electric heat in my house would sometimes kill me as often as three times in 30 minutes. I finally proved it was power fluctuations by borrowing a SOLA constant-voltage transformer. With the transformer, I didn't have any problems at all. If you can't get your hands on a good transformer, try plugging in a lamp on the same outlet with your Apple. If the lamp dims every time the Apple crashes, you'll know it's a power problem. If it is a power problem, good luck. Transformers and UPS's are expensive unless you can find one secondhand or build one yourself. It might be better to modify the power supply in the Apple, if someone knows a cheap fix. Terry Myers ESD/SIO Hanscom AFB (MYERST@ESDVAX.ARPA) ------
