I am not sure if the CD quoted is complete enough. There were three manuals published over the production life of the Mini plus supplements.
The third manual, code AKM 7169 was published in 1992 and covers non-Cooper carb Minis as well as all SPis.
The CD seems to have the first manual, AKD 4935, and only the MPi supplement to AKM 7169, which was originally released in PDF format. The latter you can download from here:

The engine, gearbox and other major components are not properly covered in the MPi supplement. It is useful information but you really also need AKM 7169.
I did buy a CD a few years ago off eBay, which had all three manuals on it but it is not always easy to identify the content of the disks.
