In the OS-9 case, definitely; LSN 0 of the disk tells OS-9 that there are
only 35 tracks (and the device driver will even double-step a 96tpi (80
track) drive to read a 35 or 40 track disk).

In the Disk BASIC case, yes, too; Disk BASIC won't even notice that the
extra tracks are there.

I got the Disto 512K upgrade, the instructions for which said I should clip a
couple of capacitors from the main PC (that's printed circuit, of course :-)
board in addition to pulling the RAM chips on said board and plugging in the
512K RAM board.  Yes, it uses DRAMs, but I don't know which kind, either.
(Sorry.)
