(or the guts to port it to a bank-switched environment like that available in the //e.) With a bank-switching coprocessor like the PCPI Applicard, it could be an interesting system. -- - Ralph W.

Ok, So I'm really shaky on it, but that's the reason I was given for why octal was so big. . . and that yes, it was a word machine with 16 bit words. However. . . *I* don't really know. The point was, it was small. >>>Hmm. Sounds like something to do after I write my thesis. >Doug Gwyn suggests >>Try adapting Minix instead.

Actually, what I had in mind was something a little more complicated, as in the original first book of Xinu. In anycase, I currently have a C compiler for the Apple, and a friend of mine is trying to get the gnu compiler to output code for the 65816 right now. I plan to have some larg memory card available, and will either bank switch in processes with ~48K limites on data/program space, or just go the 65816 option route. In anycase, you'll probably hear about this again in 2034. >-- > - Ralph W. Hyre, Jr. Sean Kamath (OK, So I'm really testing out the new 2400 baud modem I just bought.

What bug!?!?!? Spell it out for me! I may have already fixed it.
