Can anyone comment on the feasibility of a setup similar to the following one?
- Z80 processor at something like 3 or 4 MHz
- maybe a meg or so of memory, of which:
- - the bottom bit is ROM containing CP/M
- - the first 64K is that which is used as memory.
- - the highest part is non-volatile and contains a filesystem.
- USB.
- a smallish lcd display, similair perhaps to that of the Amstrad NC100
- small keyboard
and how does a Z80 normally access memory, by itself or through some sort of memory manager?
and how does I/O with the usb and keyboard normally work?
