Dopo provo con il G+DOS...
Qualcuno si ricorda o sa dove trovare la POKE che serve ad abilitare
il secondo drive? Sembra che la ROM fornita con RS lo abbia disabilitato.

Io ho queste info che riguardano la *Disciple *(non so se possono valere
anche per la *PlusD *e per BetaDOS e G+DOS...):
*APPENDIX B - THE POKE @ COMMAND*
The POKE @ command allows a value between 0 and 255 to be stored in the
variables area of the disk operating system (GDOS). POKE @ statements
can either be entered while work is in progess, to effect temporary
changes to the system variables, or written directly int Basic program
listings to cause changes every time the program is run. By reading
through the descriptions of the first few POKE @ comands, you will
quickly see how they can be used.
*POKE @0,n* (n = 0 to 8) [RBCC] default 7
The boder colour change occurs essentially every time a sector is read
from or written to the disk. This variable ins ANDed with the sector
value, then output to the screen boder.
If 0 is chosen, no border colour chagne will occur.
If 7 is chose, all sectors will change the border colour.
Therefore, if your originally set up your "system" file to allow
flashing borders, but wish temporarily to stop the flashing, you can
enter POKE @0,0; this would avoid the need to make a permanent change to
your system file.
*POKE @1,n* (n = 40 or 80 + 128) [TRAKS1] default 208
This variable holds the number of tracks and whether double or single
sided for disk drive one.
*POKE @2,n *(n = 40 or 80 + 128) [TRAKS2] default 208
This variable holds the number of tracks and whether double or single
sided for disk drive two.
