One machine I know of is an ISA/PCI machine. I'll check to see how much RAM, etc., it has. It's not networked, so being so old hasn't really been much of a problem.
It might be worth the ~$250 or so to try, as moving to a new machine with new interface boards means new software, etc., etc. None of these new hardware and software changes will make us more productive in running the equipment - it's insurance.
It would be great if it works, but if it doesn't it hasn't cost us much to try.
That's the thinking at the moment, anyway. :-)
Thanks.
Cheers,
Scott.
