[Coco] [Color Computer] COCO BASIC ROM

[Bill Pierce]

Stephen, you are wrong on this. Only RSDOS did not support the 4 new keys on the Coco 3. And they can be used. OS9 Level 2 used the alt and ctrl for alternate characters and the "keyboard mouse" feature od Level 2 that allowed you to use the arrow keys as a mouse also used F1 as the firebuttoon

Well if you want to look at the asm for basic then you can find it here:

but the coco hardware doesn't support all keys. I believe that the Coco3
keyboard matrix was entirely used up when they added the extra buttons to
it. There is no way to add more without a large modification to the
hardware. If you wanted your coco emulator to support all the keys then you
would need to modify the source code to the emulator. Out of curiosity,
what keys would you add and why?
