/* S- and D-Drives (720K) */
These are the first generation of 720K floppy disc drives from Vortex. They came in variants having either a single drive ("S" variant) or two drives ("D" variant). The "S" variant (as well as the less expensive "Z" variant) was delivered with the same double-height casing as the "D" variant, so that a second drive could be retrofitted.
The === F1-S and F1-D models are based on BASF 6138 (81690-001) type disk drives, i.e. double-sided, 80 tracks per side, 96 tpi density.===
