I decided to startup my 660AV that been sitting unused for about 9 years. No video. I checked the PRAM battery and found it was reading 1.4V, so I installed a new 3.6V 1/2 AA Lithium and the computer booted up and ran for about 2 hours off the original 230MB drive. For some reason, the 730MB (internal) was not showing. I turned the computer off and tried some SCSI terminators, without luck. The computer now only boots to the disk ?. Looking for advice - should I recap the motherboard, or install another power supply? I see a few power supply's on ebay for $35 - Astec (original is Astec), TDK and others.
