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.

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.
