Does anyone happen to have documentation, schematics,

Quay 900? It's a system based on the Quay 90F/MPS single-board Z80
computer and two MPI double-sided 8-inch floppy drives.
The drives are MPI part no. 77618022, apparently a 9406 variant but not
listed in the drive manual on Bitsavers. I suspect the pinout is close to
the SA800/850 pinout (industry standard), but I was surprised to find that
none of the variants in the 9406 manual have a pinout similar to that.
I don't know if it helps, but HPC 77618022 is mentioned in the 9406
manual, see Table 8-1:

Maybe that will give a clue as to how the thing differs from other 9406
variants.
