So they're 10 sector 5.25" floppies. Vector
Graphic maybe?
To the best of my recollection, the VGs were 16RH, not
10. To which end
I asked Dwight if a 16 hole model might be feasible.

The two Heathkit / Zenith HZ89s that I have both have hard-sectored 5.25? floppy drives. I
successfully made some new disks up when I got them (circa 1991) by making a paper
template from an original hard-sectored disk and punched holes in soft-sectored disks
using a pencil. It worked but the disks are noisy due to ?burrs? around the holes catching
on the sleeve inside the envelope.
