They appear to be in an 800k DOS-like format similar to, though not the same 
as, the Acorn 800k DOS format as used by the Master 512 (for that, see 
http://www.cowsarenotpurple.co.uk/bbccomputer/master512/format.html)

This one has two copies of an FAT (Master 512 disks have only one). The FAT 
ID byte has value xB9. The directory format also appears to be not quite DOS 
standard. There is no boot record sector or BIOS parameter block.

I am not sure what uses these. Is there an 800k format used by the ARC?
