Even if you see 3 inc disks on this tweet by Kevin Edwards, they were used on a Tatung Einstein TC-01 computer. But they hold the development archives of the brothers Tim and Geoff Follin (with their agreement of course) for C64 but also for Amstrad CPC and ZX Spextrum.

On this github page, you will be able of course to download the content of the disks (music and player code source) but also an historic of the preservation of these data which were done in two steps first by Dean Belfield then by Kevin Edwards. Sadly Geoff Follin leaved us in May 2024 due to a cancer.
