Greetings,

Thanks for all the advice about this. I'm sure I'll have more
questions after I get the motherboard. As I said before at the moment
I'm not too worried about using it as a GS, my main thought was being
able to use an Apple 3.5 drive to play games such as Silvern Castle
and Destination Mars! on real Apple II hardware versus an emulator. I
do have an Apple IIc that I also got through Ebay but it needs some
work before it will run. I've also noticed that the Unidisk 3.5 seems
rather scarce and hard to find compared to the Apple 3.5, which the
IIGS can use but not the IIc.

Thanks again,
Dean
