[Coco] CoCo3 and 16K cart roms.....

[Phill Harvey-Smith]

Hi all,

I'm trying to develop a ROM for the Dragon & CoCo that will act as a 
disk controller type rom that is started by having DK in bytes C000 / 
C001 and entry at C002.

This seems to work without problems on the CoCo 1/2 & Dragon machines, 
but falls over on the CoCo3, as it fairly early on jumps to the upper 
half of the ROM which then causes it to die as the correct code doesn't 
seem to be there.

Is there anything I need to be doing to ensure that my code is mapped 
into the E000-FEFF block?

Cheers.

Phill.
