The Bell Labs 370 port was different, it was based on running inside of TSS/370, which was an IBM OS which hardly anyone besides Bells's ESS group used.

Clem can tell us all about the IBM/Locus port to the 370.  And maybe there was another IBM port??

Much later, Sun ported Solaris to the Hitachi HDS 370 clones (for Hitachi), and then to Amdahl clones for Amdahl/Fujitsu.

Hi Tom,

Kudos for making these things available. The links are great reading
as well.

I have the strong impression that this is different from the port
at Bell Labs described in the 1984 BSTJ article; can you confirm?

Warren, can you add the links into the README or whatever that's
in the archive?
