[Albert Stinger]

I think I tackled the first part of a enhanced edit command.
Interfacing with the old command. However, there are
some questions before I can proceed. What is the state
of the mc1& mc0 rom mapping if someone has a disk.rom
plugged into the cartridge slot and then uses the edit
command, is it the first state 0 & x ?

MC1 & MC0 - ROM mapping
 0  &  x  - Ext BASIC | BASIC | Cart ROM
 1  &  0  - Ext BASIC | BASIC | Reset init | Sup Ext
 1  &  1  -         32K  Cartridge ROM
