I think it is related to the reverse function. The source code to the apple
library is contained is the cc65 source distribution so I will have a look
at that next.

Should be possible ... It would be cool to use the tgi interface and
extended memory support on the Apple IIe as well ..not sure if there are
Apple II drivers for the memory access yet.

Yeah ..we get this inverse problem fixed first.

I took a quick look at the code and could not see a way to compile a apple 2
version ..have  not had time to figure it out yet ...ar if the current
verison in cvs is based on v1.0 or V1.1 source tree's.

I was kind of wondering at first as someof the posts in Adams Contiki news
archive indicated he a version of the code that compiled (quite a while
agao) but he could not test it as he didn't have an emulator (and probably
way to busy anyway)


Rob, I sent you a couple of emails ... did you get them?
