Which Pi do you have?
I'd be willing to help with a SIMH-VAX distro for the pi. I've been wanting to write crappy shell scripts to generate simh configs anyway.

I wasn't thinking of using this for production use. Compiling the kernel on Hercules was a giggle, took like 2 days.
Could always cross-compile!
If only they could get Ethernet support working (right now the tun/tap thing is a weird point-to-point link AFAIK).
It is. It works fine for TCP/IP (at level 3) but no level 2 so far.
Really? How? I thought the level 3 works as a point to point link as I said, the level 2 stuff would let things like DECNET run.
Could possibly be done with tunnels, or hacking your own encapsulation via RJE.
I'd love DECNET on some virtual IBM gear.
Got a sample say Debian/390 setup you'd like to share?

Oh, I think so... but I'll have to dig for it. I know it works for z/OS (I can tn3270/ssh into the emulated machine, use IMS Connect, access DB2 remotely, ) so there is no reason for it to not work for Linux.
As for level 2, I think the Hercules implementation uses tunX devices, which work at level 3, so I guess it simply won't work for anything not IP.
I'd like it to support other protocols encapsulation... XCF for instance. Hercules-based Parallel SYSPLEXes would be doable then :)

Be careful when you disparage it. AIX/370 could do some good stuff and I know of a number of firms swore by it for their engineering development teams. One large semi-conductor firm used it for all the simulation of an extremely large processor in the 1980s. At the time, they claimed no other system could handle it. In fact because of the support for process migration and rolling upgrades they keep the simulation running across some upgrades to the system.
Right I want a copy - I could run this under VM in Hercules, right?

Yeah we had it at RPI and it was insanely slow. Sometimes it would drop
you during login because it couldn't process your username/password within
the 60-second timeout. And the software BS didn't help. The C compiler
was High-C and it had all kinds of bugs including choking on its own
#include files.
Fear.
Another side of the same mainframe ran MTS (from UMich) and a lot of people
never got over the culture shock, but it sure ran like a bat outta hell!
So it wasn't a slow computer, unless they horribly misconfigured the VM
AIX/370 was in, I guess.
VM tuning is a bit of a black art, even more involved than VMS tuning. (but VM doesn't have autogen ;)) Given the penchant for secrecy in the IBM world, at least compared to the DEC and UNIX worlds, I guess it's pretty conceivable that such things could happen.
P.S. I wrote the ROM half of PD.SYS for E11's new PDT-11/150 emulation and
now I'm working on the PDT-11/130 (TU58 with mutated DLV11) version for
good measure ... but slightly sidetracked attempting Terak stuff. I guess
this release is going to be all about the weird LSI-11-based micros!
That's gonna be just too much fun. :-)

No for Ultrix. And for the VAX.
Oh. Yes, of course. :)
