Re: 1.4M drive in a 800K case

[Locutus <locutus@locutus.org>]

   So let me get this straight.  If I go and by a Sony Macintosh 3 1/2
mech and put it in an Apple 3 1/2 case (those for the Apple GS) and got
a Surperdrive card, I will have a 1.4mb floppy drive for my IIgs?

   Thanks for clearing this up for me?
