Regarding Mac SE emulation on a IIgs (admitedly a hairballed idea :)

Tis possible, but I would seriously question the sanity of any
programmer attempting it. ;)

Ok, clearly state in the docs that at least a 12Mhz Zip or TWGS is
required to make this mythical emulator run at any kind of speed
even remotely resembling a stock SE.

Whoops! Gotcha here! <g> The Mac SE can indeed run System 7, with
no problems (other than pitifull speed) My own SE infact is using
System 7.1, with no problems. (Ok, so I have an AE TransWarpSE in
it... (040, 40Mhz, 128k cache) but this is only for speed, Sys 7
ran fine, but slow before)

Agreed. (especially considering how cheaply an SE can be picked up
these days. They actually make a pretty decent IIgs peripheral too,
great for dealing with .gz, .tar, etc archives, file server, etc :)
