Re: Maths With A Story 1 & 2 (BBC Micro Only)

SSD-ified these in August last year, although brief search couldn't find them anywhere on the forum.
Maths With A Story 2 is full, unsure about the one on the demonstration disk, but I guess it's better than nothing for now :?

Re: BBC-FDC floppy controller for Raspberry Pi

Drive 0 of Elite is 40 track, drive 2 is 80 track (first 40 tracks contain data, last 40 tracks unformatted, i think)
Looking at a few key points in the image, it's possible to deduce that it's the "fixed" version :)

Re: BBC-FDC floppy controller for Raspberry Pi

Can Bill confirm that FSD is only really meant to be single sided? If so I can change the code to only operate on one side at a time. I did notice that FSD only stores logical side information and not physical side - but then I guess the Beeb treats the sides as separate volumes anyway. Yes, I only...
