Disk: Atari ST
|
|
==============
|
|
|
|
Atari ST disks are standard MFM encoded IBM scheme disks without an IAM header.
|
|
Disks are typically formatted 512 bytes per sector with between 9-10 (sometimes
|
|
11!) sectors per track and 80-82 tracks per side.
|
|
|
|
|
|
Reading disks
|
|
-------------
|
|
|
|
Just do:
|
|
|
|
fluxengine read atarist
|
|
|
|
...and you'll end up with an `atarist.st` file. The size of the disk image will
|
|
vary depending on the format. This is an alias for `fluxengine read ibm` with
|
|
preconfigured parameters.
|
|
|
|
Writing disks
|
|
-------------
|
|
|
|
FluxEngine can also write Atari ST scheme disks.
|
|
|
|
The syntax is:
|
|
|
|
fluxengine write <format> -i input.st
|
|
|
|
`<format>` can be one of these:
|
|
|
|
- `atarist360`: a 360kB 3.5" disk, with 80 cylinders, 1 side, and 9 sectors
|
|
per track.
|
|
- `atarist370`: a 370kB 3.5" disk, with 82 cylinders, 1 side, and 9 sectors
|
|
per track.
|
|
- `atarist400`: a 400kB 3.5" disk, with 80 cylinders, 1 side, and 10 sectors
|
|
per track.
|
|
- `atarist410`: a 410kB 3.5" disk, with 82 cylinders, 1 side, and 10 sectors
|
|
per track.
|
|
- `atarist720`: a 720kB 3.5" disk, with 80 cylinders, 2 sides, and 9 sectors
|
|
per track.
|
|
- `atarist740`: a 740kB 3.5" disk, with 82 cylinders, 2 sides, and 9 sectors
|
|
per track.
|
|
- `atarist800`: a 800kB 3.5" disk, with 80 cylinders, 2 sides, and 10 sectors
|
|
per track.
|
|
- `atarist820`: a 820kB 3.5" disk, with 82 cylinders, 2 sides, and 10 sectors
|
|
per track.
