It's not just the *hardware*-specific stuff that will make IIgs software
incompatible with your 65802--it's FIRMWARE and ADDRESSING MODES.  Nearly
all IIgs software makes extensive use of the TOOLBOX routines in ROM.  They
will start JSLing to $E10000 to make tool calls.  Also, the 65802 only has
a 16-bit address bus (not the full 24 of the 65816), so it doesn't have
all the neat addressing modes, right?

I think some of the Merlin utilities make use of the 65802 if you have one,
but I don't know of much other software that does.
