mosbbz

This is a MOS for 6502 execution environment. It's a 6502 emulator that
intercepts the calls to the Acorm Machine Operating System (MOS) and
services them as a native console application on the host.
This is not a BBC Micro emulator. It does not emulate the BBC Micro
hardware, just the 6502 processor.
BBZ is a console program, it tries to look and feel as a modern console
application not as a BBC Micro.
