This looks awesome. The readme says it's unsure if this is v6 or v7. Diff
of a few files suggests v6 with the 'u' area being a pointer instead of a
struct and a few of the elements names changed a bit... The dates are from
1976 or 1977, which also matches...

And we have this from wikipedia: "By 1976, the operating system was in use
at various academic institutions, including Princeton
<https://en.wikipedia.org/wiki/Princeton_University>, where Tom Lyon and
others ported it to the S/370, to run as a guest OS under VM/370
<https://en.wikipedia.org/wiki/VM_(operating_system)>."  which matches the
dates as well found on the tape.

This is seriously cool. There are a few corrupted files (like dsk.h).
Kernel sources are there, but there's no userland programs apart from the
assembler and C compiler. Looking at the kernel dskio.s routines suggests
it's making an upcall to something with the sio instructions which suggests
this is the VM/370 version.

The hits keep coming!
