YOG, TIS works on windows 7, but it has to be 32 bit installation. Don't know about the newer ones.
As for the rest of the querry: this is complete TIS online. https://workshop-manuals.com/ford/puma_1998_06.1997-12.2001/mechanical_repairs/1_general_information/100_service_information/100-00_general_information/description_and_operation/about_this_manual/
What's the disc like? The online website based TIS seems a bit 'data-only' for want of a better phrase. I've got plenty of OEM motorcycle manuals, and this is unlike any of them.
ah, I've sussed how to navigate it now to the actual procedures. Doesn't help that internet access at work is heavily filtered, so certain elements are missing I think. Plus it keeps loading a 'donate' button every time I click a link.
