Hmm. Check over in comp.sys.tandy, but I think there is some odd
problem with the Model 4P drives. It may have only been that you
couldn't add more than the existing two drives without PC board
hacking, but check and see if someone has tried+failed just from the
hardware end first.

ps. Does anyone know if Software 2000 is still in business? I have a
license for my personal copy of TurboDOS, of which I have the port to
the Model 4 (in fact, the Model 4P I am typing from...) If there is
anyway to "liberate" TurboDOS, I'd go though the effort to liberate
the drivers for the ported version (myself and two others hold
copyrights to the drivers.) The floppy driver (which I wrote) could
read DSDD on the Model4D, and in fact it could read some 40 different
formats including BOTH Osborne ones... but I ramble.   _Mark_
