I have a dual 3.5 and 5.25 inch drive.
The 3.5 inch drive I bought from my local PC supplier - it's just a standard
1.44M 3.5 inch floppy, but it works fine with the BBC and Master. Cost me 13
quid. I mounted it in one of those 3.5 to 5.25 bay brackets.
By default, the PC disk appears as drive 1. If you want to use one as drive
0 you need to put a twist in some of the connections (not the same ones as
usually twisted in a PC).
