sorry about not getting back to this post, here's some more info:
m/b 1: soyo sy-7sbb ver.1 baby a.t. board(has atx power header)
info can be found
herem/b 2: atrend atc-5000, also baby a.t. has simm and dimm slots, comes with amd k7 233 cpu.
the sound cards are isa and the extra cpu is an amd k7 350 mhz.
nothing that's going to blow your doors off here, but i think you could use it for dos mame, or even and early version of windows mame w/ classics roms.
i can get a.t. psu's at the local dollar computer store if someone needs one, but it would increase shipping plus the 1$ for the psu.
i haven't tested these since i got them a year or so ago, they did work then, but i make no guarantees.
