Not really necessary. The files on those disks looked quite uninteresting.
It was just that curiosity that hit me when I was browsing through the
hexdump. I now have concluded that the second disk is infact a disk for a
Tandberg TDV21xx machine. The TOS operating system is supposed to have
similarities to ISIS. The disk structure and the presence of files like
ISIS.DIR, ISIS.MAP etc among othes.

I have seen a lot of ISIS disks archived. But I didn't immediately find a
disk with PL/M 80 and ICE80. Maybe there is.
