## 308kB 5.25" 77-track 16-sector SSDD, hard sectored
<!-- This file is automatically generated. Do not edit. -->
The Smaky 6 is a Swiss computer from 1978 produced by Epsitec. It's based
around a Z80 processor and has one or two Micropolis 5.25" drives which use
16-sector hard sectored disks. The disk format is single-sided with 77 tracks
and 256-byte sectors, resulting in 308kB disks. It uses MFM with a custom
sector record scheme. It was later superceded by a 68000-based Smaky which used
different disks.
FluxEngine supports these, although because the Micropolis drives use a 100tpi
track pitch, you can't read Smaky 6 disks with a normal PC 96tpi drive. You
will have to find a 100tpi drive from somewhere (they're rare).
There is experimental read-only support for the Smaky 6 filesystem, allowing
the directory to be listed and files read from disks. It's not known whether
this is completely correct, so don't trust it!
