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??

To really be useful, the Option Board needs completely
different software.
If you write new software for it, then it would be a nice
feature to include analysis of reversed tracks.
There is a document on the web somewhere on programming the
Option Board. (The "Confidential" stamped on it is an error
from a new clerk at my office who thought that rubber
stamps
were fun)
But, if you modify the drive for a different index sensor
(hint: I have modified 5.25" drives to index from the spindle,
instead of the disk! (for other reasons)), or repunch the jacket
(sorry, I am completely out of stock on 8" index repunch jigs),
then reversing the motor might be a way to go. SOME drives have
DC motors, some AC. Electrically reversing the motor might be
more reliable than a twisted belt.
Converting a single sided drive to double sided doesn't seem
practical either.

I haven't been able to find any API documention for the Deluxe Option
Board. If your writeup pertains to it, a URL or valid Google search term
would be greatly appreciated.

Not my write-up; just something that Central Point sent me.
It does not exactly match what I found in disassembly of
TE.COM
They wanted software to transfer files to and fro with Mac
diskettes. I told them that the [non-deluxe] Option Board
did not have enough range of data transfer rate. They went
with somebody else for the software for the Deluxe.
