The AF motor was in the lens as they did for the EOS system.
The difference is they tried to keep the flappy aperture lever and mechanical linkage for meter information.
Fortunately they saw the error of their ways and lost the FD mount and went with the infinitely adaptable all electric mount.
Another little known camera Canon continued to make well after the EOS came out was the T60 (FD mount) primarily for foreign markets.
Glad I was able to add more to your knowledge of cameras.
Have a great evening.
