Thank you Aaron, Gene and Bill.

My PC is new, it has no FD controller, hence no FD drives, but lots of ram.
My original, 128k Coco-3 has 2 physical floppy drives connected to it,
with HDB-DOS in a FD controller, 
The goal is to make a real boot floppy for the coco, that leaves
more free ram, then the repo .dsk images do (about 24k).
This can be achieved by editing the bootlist, leaving out the graphic,
sound, joystick, etc. modules, making the Term to default to the Coco's
bitbanger serial port, configured to 9600 baud, xon/xoff with a shell.

"You can access both DriveWire drives and real floppy drives on the *same*
coco, whether real or emulated, and whether in BASIC or OS9, so it would
seem there is little reason to need access to one coco's drive from another."
Well, there is a good reason. The virtual Coco (Vcc) has lots of ram,
one could easily edit the bootlist, os9gen and cobbler a new boot image
on it. On the real Coco with 24k of free ram it is impossible to say the least.
I'd like to make the above described lean, bootfloppy image on the virtual
Coco, and write it on a boot floppy with my floppy drive, connected to the 
real coco.
