CPCAI magazine claims the device has a WD1010 Winchester controller inside. The ROM seems to imply this too although the WD1010's A2, A1,A0 are not mapped to A2,A1,A0 on CPC.
The WD1010 has different commands and communication method compared to the Dobbertin (which appears to use SASI) and modern IDE (which uses ATA).
Therefore the software is *not * compatible with the Dobbertin or modern IDE drives.
FBFA ?FBFB read/writePorts seem to be:
FBFA - write command to WD1010 (write)FBFB - read status register from WD1010 (read)F9F8 - WD1010 data register (read/write) FAF8 = cylinder low?FAF9 = cylinder high?FAFA = ?F9F9 = ?F9FA = ?f9fa F9FB = ?
