810 question

[OldAtarian]

What drive mechs are known to have been used in 810 drives? Did they ever use the Tandon TM100?

I know the 810s used two types of mechanisms, the MPI and the Tandon but I couldn't tell you the model number of the mech itself. The Tandon mechs were lift-up "garage door" types whilst the MPI were push button.
