After a couple of hours of Pascal work on my //e, it starts to spontaneously reboot. After the first reboot, you can sit there, doing nothing, and it will reboot at 5-10 minute intervals.
It seems to run fine with the lid removed, so I suppose it could be a heat related problem. My system has:
-- Applied Engineering RAMWorks III card with 1MB RAM
-- Applied Engineering Transwarp accelerator
-- Super Serial card
-- Mouse card
-- Disk II controller card
The lid of the computer was noticeably warm when the reboots started, and the interior seemed warm, although nothing like the burn-your-finger temperatures inside a modern machine.
Still, I suppose some cooling is in order.
A System Saver external fan is the classic solution, but looking at the way the inside of the computer is arranged and the way the inside lip of the case comes down almost to the top of the power supply, I can't believe any significant air flow would make it in through the side vents.
I suppose I could mount a small fan somewhere in the chassis. Is there a preferred solution?
