Right I want a copy - I could run this under VM in Hercules, right?
z/OS, AIX/ESA[370] and Debian/390x all under one emulated z/Arch box. That WOULD be cool.
If only they could get Ethernet support working (right now the tun/tap thing is a weird point-to-point link AFAIK).

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. :)

If you could, you'd be the first! What a waste of a perfectly good

I have to agree. I love UNIX, but running anything other than MVS on
something like that, or maybe VM, is just a sin.
Why not as a VM guest?
Well I thought that was sorta implied. :)

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.
BTW; AIX/370 and AIX/PS2 are actually similar (much in common) code base. They were developed by Locus Computing Corp for IBM by the late Gerry Popek. Check out his and Bruce Walker's book: http://www.amazon.com/Distributed-System-Architecture-Computer-Systems/dp/0… for the details.
The really cool thing that these versions of AIX supplied was TCF - the Transparent Computing Facility. A total of 32 nodes of 370s and PS/2 could be "clustered" into a "single system image" and operated as a single computing environment (yes root on a PS/2 gave you root on the 370). I once saw some one unbox and plug a brand new PS2 into the network. He put a boot floppy in it, turn it on and with that have it "join" the cluster. In the background it populated its disk using replication.
Although neither VMS nor Tru64 would never completely match everything TCF could do, (they never had the full process migration stuff), Locus did sell some of the technology to DEC and it would land make it into TruClusters and DEC would develop similar things for VMS.
Check out: www.openSSI.org The technology still is around, although Beowulf style clusters (which are not full SSI) have usurped the market. Which is actually real shame. AIX/370, VMS, and TruClusters were really ahead of anything we have practically speaking today. I miss full SSI and a cluster where I can move process anywhere - I just saw one giant resource.

Hello!
Close but no noxious smoking device Mark.
That was AIX/ESA. I'm talking about AIX/370. And according to one
associate on another two lists, (One I manage.) that one ran on one
specific customer's machines in the same area that one of our
associates is based in.
If John Wilson is correct and it also ran on the mainframe there,
sharing space with the MTS setup then it adds to the mysteries behind
the product.
And to add the the amusement I also met a family of machines running
ESA grade operating systems, a good long time ago, also a crowd of
RS/6000 machines and a very unhappy IBMer. The surprised look the
woman gave me was worth it.
This was the same time when Ultrix was announced for the VAX, and then
work was being started on the Alpha family, especially since I saw a
couple of MIPS based workstations then as well.
And speaking of that, there are materials available on the TUHS ftp
site for it.......

To add to the data points, PSU ran AIX in a VM on their 370 as well. It may have been AIX/ESA instead of AIX/370 as I don't remember the particulars anymore.

Not to take over the DIgital group but did anyone here ever run the Amdahl unix on 370??
