I believe you have two choices.
1) Just take the Zip disk from the Gateway to the PowerMac and read the
files. You may have to use a file converter like FCS Assistant (which is
free on the WWW) or BD's FACSConvert, but it should be fairly straight
forward since Mac's have no problem reading PC formatted Zip disks.
2) Buy a copy of a "MACLan" which is software that lets Win95 computers and
Macs talk on a peer net basis, and buy a cheap 10 Mbps hub. Make sure your
Gateway has an ethernet card in it, if not buy that too. Then you should be
able to hook it all together and each HD will show up on the other
computer. Should also be easy, and saves you dragging disks all over the
lab.
Good luck.
