The Hard Disc OS for the SD IDE Interface.
Tragedy struck for HDOS when the source was lost in a drive crash on one of Nev’s machines:
Quote from Format Vol 12 No 2 (Jan 1999) from Bob Brenchley:
Nev Young wrote HDOS using a C compiler on the PC which was designed to produce Z80 object code as its output. This was by far the most efficient way to write the operating system, I know because Nev and I talked it over on the telephone and in person for many (many) hours. However, due to a faulty hard drive on the PC, the C source for HDOS no longer exists.
