A 720K 3.5" IS a DD drive.
Depending on the specific model, the Kaypro will only see 40 tracks of the
3.5", and may or may not support using the second side.
There was substantial third party support (Advent? Micro Cornucopia, etc.)
for DS 80 track ("720K") drives on Kaypros.
One quirk about the Kaypro format, is that it puts an incorrect value in
the head number field of the sectors on the second side. But, it doesn't
seem to object to a disk having the correct value there.
