Why couldn't you put a
double sided disk in a single sided drive and read it off. My Commie
1541-II used to read the one side of a single sided disk. Maybe I don't
have an acceptable understanding of what the Option Board/software does.
Your commode doesn't use index pulse.
With the option board and a double sided disk in a single sided
drive, you will be able to read the first side of the disk.
If you flip the disk over and put it in backwards, the
Option Board SOFTWARE will not work at all, because it won't
see any index pulse. (NOT USED in Commode, Apple][, and Atari)
IF you repunch the jacket, or modify the drive for an
additionalindex sensor, so that it sees an index pulse,
then the Option Board software will still be useless,
because it can't understand backwards tracks, and they
never considered adding such a capability to the software
just because you won't get a double sided drive for your
double sided diskettes.
IFF you repunch the jacket or modify the drive, AND write
your own software from scratch for a flux-transition board,
then there is no reason why you couldn't read the second
side of the disk by flipping it.
Is it THAT hard to find a double sided drive??
