Thanks for the detail! I meant "second after PDP-11" so the confusion
was only an off-by-one error.

The topic for my talk next week. Unix had virtualization in 74. The
second Unix port ran under OS/360's VM in 78.
I thought the Interdata port was second?
Wollongong to the interdata?7/32 was April of 77. Went into production
July 77.
Bell Labs to the closely related interdata 8/32 was June of 77. Never
went into?production, but portability fixes plowed back into V7.
Tom Lyons had his booting to a similar level around May of 77 ("end of
his junior year"), though he wasn't hired by Amdahl unti the following
summer and he reports having the full V6 up early in 1979. V7 up later
in the year when they got it from AT&T.
I kinda lump the two interdata ports together as 'the first' and I don't
have good dates for when Tom Lyons booted beyond hello-world, or what
the benchmark for 'first' should be.
