The Disk Basic 1.0 ROM does not support the DOS command, so you need to 
have a second boot disk with a file named "OS9LOAD" to load it.

The 26-3022 controller is somehow detected by stock Tandy OS-9, and it 
will not access double sided disks on it.  Hopefully Nitros-9 does not 
have that limitation.

The Disk Basic Rom 1.0 ROM is different enough in the undocumented 
locations that my program written to run ROM Basic under FLEX-09 will 
not run with the 1.1 ROM.
