DSQD generally means 80 track two sided drives such as
TEAC FD55F or G and double density encoding. Typically
they store around 800k.

FYI that can mean hard or softsectored as that is controller
not drive dependent.

Kaypro with Advent turborom, AmproLB, Micromint SB180
to name a few.

St225, ST251 and related drives are fairly common.
