I haven't counted but I would guess that there are about five hundred discs here. They are nearly all 5¼" but there is one box of 3½" discs.

There is tons of software here from the Welcome Disc, Beebug Magazine disc to shareware from BBC PD and 8BS.

A good proportion of the discs are DOS type discs for use on the Master 512 including an original set of the four Master 512 discs.

I haven't had chance to look at many of the discs yet but will be doing so over the coming weeks.
