I have an old PC out of an automotive alignment machine. It has a CB60-BX rev b+ board with a socket 370 Celeron 733/66 and 1 stick of pc133 128 RAM.
Before anybody recommends a new one, the machine has 2 very large ISA slot cards that interface to the Alignment machine. Any more recent PC won't accept these. Also I don't have any backup discs for the alignment program so I need to use the hard drive it has(WIN98).
So when I turn it on, it has 1 long beep that keeps repeating. The CPU fan runs and the beeps is all.
The MB manual suggests that the RAM is bad. I have tried 3 different sticks in all 3 different slots with no improvement. I also cleared the CMOS and tried a different CPU, p0oer supply and video card.
Yeah I did find one CB60X-BX on eBay for $331 buy it now. I can't imagine why the high price.
I found I had an old Tyan BX board here that booted up. I won't know until I mate it to the alignment machine if it works.
I still like to know why the old board didn't boot up.
