I only remember seeing the 32 pin ones on 386 machines. Do you have 72 pin SIMM sockets? I'm guessing the EDO variety doesn't work on most 486's?
Many of the earlier 486s used 30 pins (not 32 pins) simms, and mostly had 8 slots (divided in two banks) for them, although I also owned and old 486 which could handle 12 of them. Later 486s were built for 72 pins simms, in which case you only need 1 simm per bank and could use (much) larger simms. Although some 486 mobos would work well with EDO (I owned one such board), it would not take advantage of it, as it would work as if it was fastpage memory.
I owned one of the last incarnations of a 486 motherboard, which therefor was pretty advanced: it could handle 128 MB of ram (two 64 MB simms), had three PCI-slots (and two or three ISA), two IDE-connectors and could handle 8 GB harddrives. It has served me well over the years with a P24T/83 as its cpu, running Windows NT4 very reliably.
