My suggestion would be to read previous threads
on this subject. From what I can gather, the most
difficult thing isn't the interface hardware, but
getting someone to write the drivers for each of
the individual devices you want to use. Also, how
about memory? The Apple II, except for the IIgs
possibly, is very limited when it comes to user
ram, and when you take up that ram with a large
driver, how would you load a program? I believe
that USB is just one of those things that we will
simply have to do without.
