Yeah, Corkyg, that would be my plan - that Supermicro is going to chomp the wallet. But there are a few on Newegg and one on Compgeeks.com that are reasonably priced that have one ISA slot. There are some new Socket 7s and Super Socket 7s on eBay that have several ISA slots. And there is a Socket 370 on eBay that has one ISA.
. In any case, those ISA cards have to be getting up there in age. Electrolytic capacitor lifespan is around 10 years - so it won't be long before they start crapping out unless you have them refitted with all new caps anyway. Time to look for a modern equivalent - nothing is forever...
