## 800kB DSDD with PHILE

pSOS was an influential real-time operating system from the 1980s, used mainly
|
|
on 68000-based machines, lasting up until about 2000 when it was bought (and
|
|
cancelled) by Wind River. It had its own floppy disk format and file system,
|
|
both of which are partially supported here.
|
|
|
|
The PHILE file system is almost completely undocumented and so many of the data
|
|
structures have had to be reverse engineered and are not well known. Please
|
|
[get in touch](https://github.com/davidgiven/fluxengine/issues/new) if you know
|
|
anything about it.
|
|
|
|
The floppy disk format itself is an IBM scheme variation with 1024-byte sectors
|
|
and, oddly, swapped sides.
