Yes.

I did not mistype. I have a 16-sector RK05F pack. It was in the drive when
my former employer bought it c. 1982 from Ohio State University surplus before
I worked there. The tech guys removed the F pack and used the RK05J and RJ05F
in the rack with an RK-11C (which I have somewhere). I got the pack off the
shelf in 1984. I have never owned an RK8E, nor a working RK05F, but I do have
at least one working RK05J (one's in the basement, almost certainly working,
attached to an RKV11D, the other is in the shed and is of dubious value).

The drive doesn't care except for number of tracks and magnetic gap (the
F heads and J heads are different). The boards are the same (there are
jumpers to select modes of operation). The controllers are the parts that
care how many sectors of how many bytes there are.
So... can *anyone* out there read a 16-sector RK05F pack? I have no use
for it since. as I said, I have no RK8E nor working drive.
