I have just finished translating a copy of
Apple Roots: Assembly language programming for the Apple IIe & IIc by Mark Andrews.
This is a really good book that explains concepts clearly and also gives
examples of how they are used. If anyoneone wants a copy of this
PM me of what books you have on the Apple (in digital realm of course, PDF format, etc)
and we can do an exchange.
I have also translated a copy Programmer's Guide to DOS, which I have
not seen anywhere. I am willing to do the same for that also.
