Hi!
Some of the stories on here reminded me of the fact that there's also likely
a whole boat-load of UNIX ports/variants in the past that were never released
to customers or outside certain companies.
Not talking about UNIX versions that have become obsolete or which have
vanished by now like IRIX or the original Apple A/UX (now *that* was an
interesting oddball though..) and such, but the ones that either died or
failed or got cancelled during the product development process or were never
intended to be released to the outside ar all.
Personally I came across one during some UNIX consultancy work at Commodore
during the time that they were working on bringing out an SVR4 release for the
Amiga (which they actually sold for some time)
Side-note.. Interestingly enough according to my contacts at that time inside
CBM it was based on the much cheaper to license 3B2 SVR4 codebase and not the
M68k codebase which explained some of the oddities and lack of M68k ABI
compliance of the Amiga SVR4 release..
However..
It turned out that they had been running an SVRIII port on much older Amiga
2000's with 68020 cards for some of their internal corporate networking and
email, UUCP, etc. and was called 'AMIX' internally. But as far as I know it
was never released to the public or external customers.
It was a fairly 'plain jane' SVRIII port with little specific 'Amiga'
hardware
bits supported but otherwise quite complete and pretty stable.
Worked quite well in the 4MB DRAM available on these cards. The later SVR4
didn't fare so well.. Paged itself to death unless you had 8 or even (gasp!)
16MB.
It was known 'outside' that something like this existed as the boot ROM's
on
the 68020 card had an 'AMIX' option but outside CBM few people really knew
much about it.
It may have been used at the University of Lowell as they developed a TI34010
based card that may already have had some support in this release.
Still..
This does make me wonder.. Does anyone else know of these kinds of special
'snowflake' UNIX versions that never got out at various companies/insitutes?
(and can talk about it without violating a whole stack of NDA's ;) )
No special reason.. Just idle curiosity :)
Likely all these are gone forever anyway as prototypes and small run production
devices and related software tends to get destroyed when companies go bust or
get aquired.
Bye, Arno.

I’ve read from early Microsoft employee’s that you had to learn to use vi to get vacation
time, as they ran Xenix on all their backend stuff. Although their first Xenix ads did
mention it was available on the PDP-11, and other than one old post where someone
mentioned that anytime there was a serious bug it was always in the Xenix portion.
It’s kind of funny that despite at one time being the highest installation by site count,
Xenix has all but disappeared. Not that OpenSERVER was either open or much of a good
server. And the only people I ever saw all that excited about UnixWare was telecom
companies.

There is that emulator shoebill which can run A/UX, even the 0.7 version which has the
lower level unisoft sysv source.
But by the time they got around to version 3 it was an incredibly robust UNIX with a very
simple UI, and by nature had access to an incredible amount of apps being source sysv
compatible, and could run most sys6/7 apps, including SoftPC!
It's crazy that Apple never ported it to the PowerPC, as they basically had a next
gen OS right under their nose the whole time, and ended up paying to port NeXT to the
PowerPC, and doing the carbon shuffle to get apps... But Apple has never been shy from
doing things strange.

AIX/370 was a real product. One of the ones that I don’t ever think saw the light of
day was the i860 AIX port. IBM made two i860 add-in cards for the PS/2. The single
processor version was called the Wizard and there was a 4 processor version with an
integral frame buffer called the W4. We ported AIX to both. The i860 version
actually had more in common with the 370 version than it did with the 386. All of
these AIX versions came from the same source code and used the IBM TCF to allow you to
transparently run executables across nodes in the cluster. The only AIX that didn’t
play was the completely independent (and in my opinion somewhat brain damaged) IBM/RT
UNIX. If there was a TCF-based RT kernel, I never saw it, even inside the IBM labs.
Speaking of odd job control mechanisms. The 386 side had a device that multiplexed the
PS/2 console into multiple streams called the “High Function Terminal.” When we wrote
the virtual console for the Wizard/W4 add in card, we called it the “Low Function
Terminal."

I had never hear of an i860 board from IBM, but a little searching, and it almost looks
like it was going to be a thing.
NUMBER 290-817
DATE 901218
TYPE Programming
TITLE INTEL OS/2 AND AIX I860 SOFTWARE DEVELOPMENT TOOLS FOR C AND FORTRAN
ABSTRACT Today, IBM announces C and FORTRAN compiler support for the
PS/2 (R) Wizard Adapter running under both AIX (R) PS/2 and OS/2 (R)
operating systems.
< hundreds of lines of information deleted >
TECHINFO TECHNICAL INFORMATION
SPECIFIED OPERATING ENVIRONMENT
v MACHINE REQUIREMENTS:
| o The Intel OS/2 and AIX i860 Software Development Tools for C and
| FORTRAN require one of the following PS/2 system units:
| - PS/2 Model 70
| - PS/2 Model P75*
| - PS/2 Model 80
| - PS/2 Model 90 XP*
| - PS/2 Model 95 XP*
| The Model P70 is not supported.
====> * These models are not currently supported by AIX PS/2.
Therefore, the PS/2 Wizard Adapter will operate only with IBM
OS/2 on these models.
Or later something like this:
IBM architecture - RT
IBM architecture - RS/6000
IBM architecture - S/370
Intel architecture - i386
(rumors of)
Intel architecture - i860 (Wizard PS/2 cardset with 4xi860)
whatever comes out of Steve Chen's supercomputer work
Of course, with IBM not licensing AIX source to anyone, these are only
IBM machines, but that is not the same as AIX being a non-portable OS.
Rumors are that IBM's customers are pressing very hard for source
licenses and that someday such licenses will be available. Whether
that would lead to ports to other machines, I can't predict.
Very interesting!

We had RTs where I was. By the time I came on the scene, they were being
decommissioned in favor of RS/6k hardware (arguably, the RT was pretty
low-powered even for its day), so the students were running around grabbing
them and playing with them. We ran AOS on ours, which was a more-or-less
straight port of 4.3BSD+NFS (maybe they started with Tahoe? I don't know),
but IBM seemed to want to push AIX with them. The RT was my first exposure
to "real" Unix source code.
What was interesting to me was all of the #ifdef's in the source that made
it clear that someone at IBM had obviously tried to port 4.3 to the 370. I
don't think that ever saw the light of day, but there were definitely
vestiges of it in the kernel.
I had understood was that AIX/370 was actually OSF/1 based and totally

wrote, it sounds like that wasn't quite right.

Hello!
We (well most of us) all of us know about AIX. Well what about AIX/370?

AIX/370 was a real product. One of the ones that I don’t ever think
saw the light of day was the i860 AIX port. IBM made two i860 add-in
cards for the PS/2. The single processor version was called the Wizard
and there was a 4 processor version with an integral frame buffer called
the W4. We ported AIX to both. The i860 version actually had more in
common with the 370 version than it did with the 386. All of these AIX
versions came from the same source code and used the IBM TCF to allow you
to transparently run executables across nodes in the cluster. The only
AIX that didn’t play was the completely independent (and in my opinion
somewhat brain damaged) IBM/RT UNIX. labs.
Speaking of odd job control mechanisms. The 386 side had a device that
multiplexed the PS/2 console into multiple streams called the “High
Function Terminal.” When we wrote the virtual console for the Wizard/W4
add in card, we called it the “Low Function Terminal."
Did the HFT survive into the RS/6k? I seem to recall hearing about that.
Perhaps it was an option on the RT, or somehow could be used with the
"crossbow" card on the 6152?

No wonder, given what they did to the poor chip it ran on. #6-)

Exactly right. TCF - Transparent Computing Facility -- No mean trick...
you can mix PS/2 and 370 in the cluster, so root on desk allowed me root
on the mainframe too. What was cool was that the TCF will look at the
executable and find the proper CPU. The big mistake was that that node id
was stored in a single 32 bit word and assigned per bit, which was a
scaling issues.

with the original UCLA work. I did not work on the IBM project, although a
number of my peers did. I was higher to help developed TNC - Transparent

TruClusters and a never shipped HP Cluster Product. Many of the same ideas

never be any concern about ownership. The architects like me and Roman,
were allowed to talk to the AIX architects, such as Bruce; but we keep
separate development environments at separate sites. After the IBM work
ended, all of the Locus distributed system folks the struct around went to
work on TNC and the technology go sold off and licensed. What was
interesting is that TNC was open'ed sourced after the Compaq/HP mergers and
put into Linux but I've forgotten the URL (I'll search and follow up).
It's a real shame it never went anywhere. It was a very, very cool.

That was IBM politics. LCC has the contract for the original AIX port to
the 370. When the RT was developed, the Austin team was ramped up. One
of our members of the TUHS list who is remaining silent I see is not saying
why but I know was there ;-) and might known the actual politics, I never
did. But when the AIX/RT port was forked, they started with AIX/370 code
base and removed the TCF code. But LCC still had the AIX/370 contract
from Enterprise system group to maintain AIX/370. And also, Locus had the
contract from Entry Systems, who all they wanted TCF. So AIX/386 and
AIX/370 as Ron points out were one code base, one dev team (at LCC in
California).
Dan Cross said: "I had understood was that AIX/370 was actually OSF/1

It maybe that by the end, the user space was based on the OSF/1 user space
code. That was true for HP and DEC also. But I can definitely state
AIX/370 and AIX/386 were one set of source trees and all of was done by
Locus Computing Corporation certainly through the mid 1990s.

Slightly off or on topic, but since you seem to know, and I've never seen aix 370 in
the eild, did it require VM? Did it take advantage of SNA, and allow front ends, along
with SNA gateways and 3270's?
Or was it more of a hosted TCP/IP accessable system?

Hello!
Well before it was withdrawn from marketing, it played in a big pool
Namely the mainframes at one of the universities in Norway. And I got
this from a VMer I who is best known for writing the pipelines stuff,
And sadly that was its only customer.
By contrast AIX for RS/6000 gang and its ancestors were well taken
care of and its still available.
