The Z80 splits the memory into multiple banks of 64K each. There is a setting
in the chip that keeps track of the current bank, so any memory address refers
to the address in the current bank.

The TI-86 has 128k, 96k user accessible, or something like that...

How does it access all that memory with a Z80 chip? It has 16-bit memory and
instruction pointers?

Someone please take pity on my poor newbie question.
