ISIS-II disks with PLM80 and ICE80 software.

[Oliver Lehmann]

Hi Mattis,

all I can contribute here are german IS/M Manuals of my P8000 which state,
that this IS/M is compatible to ISIS II 4.1.
Most likely, this IS/M is just a copy of IS/M + modifications to the specific
hardware.

No idea how helpful german text is to you though....
But that is all I have

http://www.pofo.de/P8000/notes/books/IS_M_Systemhandbuch/1988_06/IS_M_Systemhandbuch.pdf

There is a disk format section on Page 13 chapter 4.3.
A kinda verbose description of the filesystem is in chapter 4.4,
page 13 and following.

Since it is a PDF, maybe google translate can help a bit...

Regards,
Oliver
