Gene, not quite right
Color BASIC starts at $A000
Extended BASIC starts at $8000
Disk BASIC starts at $C000, and there's a 'mirror' at $E000 due to the
16k decoding of the CART output.
In fact there was a trick to get 8k more for color basic programs on a
64k CoCo by copying the ROM to RAM and somehow switching off the
Extended BASIC functions. I remember it appearing in Rainbow but I'm not
sure if I ever used it for anything practical.
