	Just to clear something up. The above fact is true for a _stock_ 
out-of-the-box Apple III or III Plus machine. Using Apple III hardware, you
could only emulate a 48k Apple ][ Plus -- even though it would have been
possible to do more, had Apple not purposely barred III-specific features
from emulator software. However, Titan (I recently learned) produced a
hardware slot-based card which emulated an Apple //e. Quite simular I suppose
to the Mac LC //e card or IBM-PC TrackStar //e card -- it used a combination
of independant hardware and software for emulation. The Titan card allowed
the III to emulate a 128k Apple //e, 80 columns and Double-Hi-Res graphics.
Only drawback was it was an unehanced //e (no mousetext, 65C02, revised
firmware, etc) and it could access no more than the 128k of RAM supplied
on the board. I've no idea if an enhanced Titan board later came to be, 
though I doubt it since the Apple III market was probably dead by late
1985, early 1986. Oh well, it did allow you to replace the 6502 with a
65C02...perhaps enough to run ProTERM or the latest version of ProDOS. :)

	On a related subject, wasn't a 3rd party company designing an
Apple III emulation card for the IIgs? I seem to remember seeing this in 
some newsletter long ago. Maybe it was the joke section...? ;-)
