That is exactly what I want because my ROM is not intended to be a 
DOS.  Since the EPROM Pak and floppy controller ROMs don't actually 
auto-start, Extended BASIC will do it's thing then transfer control 
to what it thinks is a Disk BASIC ROM because it sees that the first 
two bytes "DK".

The CoCo 3 emulators in M.E.S.S. are crashing the CoCo when my ROM 
attempts to switch to ROM mode, even if I mask FIRQ and IRQ 
beforehand.  I don't know if this is a M.E.S.S. thing or what will 
happen on a real CoCo 3.  I could only stay up so late last night.
