Hi, folks. Tom Lyon here - this UNIX 370 stuff was
recovered by Stephen at
LCM+L from DECtapes that I've had sitting around for 40+ years.
You can read all about the Princeton/Amdahl project here:

If anyone wants to get serious with the code, you'll need Hercules with a
VM/370 image as well as a PDP-11 emulator running V6. There's not a lot
beyond the kernel, I got the shell working enough to prove that fork
worked, and then ran out of steam because of the awful communication
problems between the PDP and the IBM. [ But that was my start as a
networking guy ]. I personally haven't had time to do anything with the
recovered bits.
I've been lurking on TUHS for a while - a special Hi to Ken Thompson and
Steve Johnson. I owe a lot to each of them. Read about my summer at Bell
with the Interdata 8/32 here:

These are interesting bits that add to the flavor of what we know already.
Thank you for taking the time to write this up...
One interesting thing from this. Your UNIX 370 port was started before the
Wollongong Interdata port. Your work on Unix 370 started in August of '75,
but the Wollongong port started in November '76 and was put into production
in July '77.
And we have the TSS/370 port described in the BSTJ, and the Bell Lab's
Intersil 8/32 port. It makes me wonder what other porting efforts had
started in the 75-78 time frame....

All, the second Unix artifact that I've been
waiting to announce has
arrived. This time the LCM+L is announcing it. It's not the booting PDP-7.
So, cast your eyes on https://www.tuhs.org/Archive/Distributions/IBM/370/
Cheers, Warren
P.S Thanks to Stephen Jones for this as well.
