Old BX board won't boot- just beeps

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.

Any idea what to try next?

Or try to find one on eBay. Search for "pentium isa 440bx" and you'll find several, including an ITOX CB60-BX for $650.

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.
