This is, unfortuately, not much. The Z80 can address 64K of memory (twice
what the ti-85 has). Now, if you do something like the 86 does with a paging
system, then you can address more, however it's a good deal more complex,
and individual programs really shouldn't exceed 64K. It can also be very
slow.
