For the third time in six months, the PC running my CNC mill has broke.
First time, the hard disk fried. Second time, CPU cooling fan quit.

This time the computer won't try to boot to any drive. No messages at all
from POST on the monitor. For that matter no text at all. Power supply
cooling fan comes on, CPU cooling fan on, strange sound from a drive (can't
really tell which one). I need an ISA slot, or I'd just buy another box and
be done with it. Any suggestions?

Do you really need an ISA slot, or it the card something that can be had
in a PCI version for not too much money? I.e. is it a servo controller
card, or just an extra parallel port card?

Some of the Dell Optiplex business systems have a single ISA slot
available depending on which version of riser board is in them.
