You could utilize EBay and get the Asus P2bf, 2 ISA. It would not be new but if that's not essential an option you may consider. It will take Coppermine/100mhz at 1GHZ, slotket and CPU or cartridge.
I just bought a second P2bf to build up a PC for my better half- the wife. My first P2bf is a retail purchase and it is very good.
I want a big American automobile with tail fins!
