I have an HP "Pompard" prototype disk drive, made in spring of 1984.
It's a dual 3.5 inch drive in a 9121-like case, but with an HP-IL
interface rather than HP-IB. It's not battery powered, but I believe
that the HP 9114A was derived from this design.

There are jumpers in the unit for one drive or two, and for
single- or dual-head drives. But it's not apparently which way
the jumper setting for the heads is, and I can't see enough through
the flap to tell if there are two heads by visual inspection.

The drives are Sony model OA-D32W. Does anyone know from that model
number whether they are single- or dual-head?
