Is the whole interface spec available anywhere?
There was never any formal standard. The closest thing is the ST

That doesn't cover some of the changes introduced in later drives, such
as the head select 3 signal that replaced reduced write current, first
introduced with the Maxtor XT-1105 and XT-1140, and documented in the
Maxtor XT-1000 Product Specification and OEM Manual:
