And incidentally what would it take to upgrade a II to utilize superdirves. Heck I thought my SE had one, but I'm not positive. Is it simply a rom upgrade, or is it a function of the hardware?" The floppy controller chip is what needs changed on the SE, not sure if the one on the II is solderd on or removable ( I don't own a Mac II). The batteries (2 needed) for the II are 3.6V 1/2AA axial leads (soldered to the motherboard unless it has been modified). New model IIx/IIfx etc have socketed batteries.
