Re: Drive speed pot for Disk ][?

[Mark Graybill <saundby@neworld.net>]

OK, I didn't read through the section on adding an external pot to the drive, or I
would have known I had the right board (which has only one pot on it.) The gif
would not have been much help, though. It shows the side of the board that I can't
see well without detaching the board from the drive (the trace side, rather than
the component side), and it's a bit sparse on detail (not that it needs much for
the project).

Maybe a note in the FAQ section on how to adjust the drive speed - mention the
location of the board and the "VR1" masking next to the pot. That should be enough
to get anyone there.

Thanks for your message (and the FAQ. It's astoundingly comprehensive.)
