I think DWDOS is great because it reads everything included boot track
(kernel) over DriveWire. You just need to load the small DWDOS command
from floppy or even tape. Get it from the Files section at
toolshed.sf.net and use for the CoCo3 one of the files called
dw3dos*cc3*
- wav is for tape
- bin is for loading off a floppy
- trk is for writing into a boot track on a floppy, so that "DOS" will run DWDOS
- dsk rom is for putting in a cartridge
- mb rom is for replacing the BASIC ROM
