In case you ever pass through Pittsburgh, Dave has 370s of various flavor and some pdp-11s.  I’d be pretty entertained trying to get this running in some capacity on real iron in the future when I visit Dave.

I may put out another form to see if people would be interested in doing an event there.

In the meantime thanks for recovering and posting this.

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:

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

Cheers, Warren

P.S Thanks to Stephen Jones for this as well.
