- Nope. That's how all 64k XL/E computers access memory. Since the 6502 is an 8
- bit chip it can only "see" 64K at once. 48k of Ram and the 16K O.S. In order
- to see the extra "Bank" of memory (i.e. the other 16K) you have to swich the
- new bank with the O.S. or (now, I may be mistaken about this) with one of
- the other banks of RAM. So this should not be your problem (unless, of course,
- for some strange reason the 1200XL banks memory diff than the other XL/E's, but
- I doubt that).
