On the Pro, the software sees a fairly traditional CSR
set with disk address registers (sector and track). So an assumption like the one you
worry about would be in the controller, not the OS. If it works at all then that would
say the controller doesn't make that assumption.
Yup, things just seem to work. I even was able to boot the diagnostics
disk from virtual floppy, you just have to remember which Gotek is DZ1:
and which is DZ2: and wait a few seconds after switching for the Gotek's
to "settle down" when swapping images.
But it works, my DECNA passes all diagnostics, and it looks like it also
passes the loopback tests for DECNET 3.2.
Now to figure out how the TMS software works.... :-)
