This is a bit naive. The factors that made the apple ][+,e 
difficult to 'compatiblize' have been fixed with the ][gs.
The biggest stumbling block is the lame screen mapping on the
old apples. The linear screen area on the new apple with eliminate
a major problem. Other problems like memory management have also
been repaired with the new hardware. It should, therefore, be significantly
more simple to create a PC clone card for the gs than it was for the
][+,e. This, in turn will drop the price of the card. The "very
reasonable price" should be possible because now they *won't* have to
create a whole PC clone on the card, just a 8088 processor and bus interface.
Previously, one had to add memory and graphics hardware, as well as deal with
incompatible file formats and other problems.
