Doesn't all the IIgs's ROM count as part of the 24-bit (.'. 16MB RAM)
address limitation, making a limit? I'm guessing the IIgs doesn't
have 8MB of ROM, but a ROM-switching-in-and-out thingiey like in the
//e et al. was probably never added to the IIgs, making the bulk of
the IIgs's ROM pretty much stuck in place. Assuming I'm right (am
I?), what would the theoretical RAM limit be (I mean GS RAM, of
course, not "Slinky", Titan, et al.)?
