Micropolis 1043 II

Floppy Disk Drive


Model Capacity Size Height Media Type
Micropolis 1043 II 315K 5.25" Full Single Sided, Double Density / 100TPI

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.

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.


Model 1043 Mod II is a master module, used with a Micropolis 1071 controller and interface cable A. Its sister-module 1023 Mod II is an add-on module only.

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.
