Complete
MetaFloppy™ single-disk subsystem with a total of 315KB
of formatted on-line storage. Includes one disk drive, S-100/8080/Z80 compatible controller
(Model 1071), drive enclosure, interface cable A and power supply.
The 1043-II is the single-drive version of the
1053-II
dual-drive. It is a single head / single-sided drive. The roman numeral "II" indicates it
operates at 77 tracks / 100 TPI. This drive only accepts hard-sectored media when used with the bundled
Micropolis 1071 controller.
As model
1043 Mod II is a master module, a very common setup was to have one 1043-II and the
sister add-on module 1023-II, both driven by a
Micropolis 1071
controller card and connected with
interface cable A.
Another possible setup would be to have two 1043-II subsystem kits, one "drive 0" master drive, usually in the
form of a "1015-II F" drive mechanic with another 1043-II, internally a 1015-II, as "drive 1". Both of these
setups would be an alternative to dual-drive model 1053-II.
There's another variant of the 1043-II, the 1041-II, which has no power supply or regulator/
heat-sink-package but a bundled power cable instead and a leaner enclosure so it can be
used in desk-top-mode or installed in a chassis.

Note on Micropolis' floppy drive naming convention
If you ask yourself what the meaning of the Roman numeral literals in disk drive names
is, here's the explanation: Labeling convention for the Micropolis floppy disk drives
from the 1040/1050 series is that each model number is followed by either the notation
"Mod I" or "Mod II". These notations indicate whether the system operates at a track
density of 48 TPI (35 tracks total) or 100 TPI (77 tracks total). "Mod I" storage modules
have a black disk load actuator and "Mod II" modules have a blue disk load actuator.
