My CNC control computer quit for the umpteenth time due to CPU
overheat...

The little plastic tabs that hold the cooling fan to the CPU keep
breaking off. I found a way to clamp the cooling fan back on when the
first and second one broke. Friday the third one went. Spent most of
the day Saturday getting a backup computer running. But, I should get
this repaired.

OK, its a SOYO SY-P4I84PE ISA motherboard. Here's a link that shows a
picture of it:

only $495 or a new one for $1295. guess they won't give ISA slot
motherboards away. I just need the little plastic base that goes
around the slot 478 CPU and the clamp levers (lost one). This has GOT
to be a part used on other motherboards. Anyone know computers well
enough to know what scrap MB to look for?
