One might wonder if there is anything left to discuss
other than history... And most of us veterans of the
big B or Sperry are not getting any younger.

Looking at the current Unisys website there is still mention of
Clearpath Forward and AB Site (was Enterprise Application Environment,
was LINC) but it is well buried.

I was wondering whether there were still mainframes (MCP and OS2200)
still being sold. I am from the MCP (Burroughs) heritage.

Those of us who came through from Burroughs or Sperry will now be well
into retirement but there must still be some involved with production
systems descended from these times.

Both V-series and A-series can be considered MCP. The last V-series
was decomissioned circa 2010. I believe that there are still
A-Series (Clearpath Libra) systems running, albeit in emulation on
Intel hardware. Likewise the Univac descendents.

I'm from the 2200 side and retired the day the last system I was - in
part - responsible for closed down. If I was still working now, it
would definitely be only part time, as in a couple of days a week.
Retirement age has since come and gone.

Also being old, decrepit and retired I have no first hand knowledge
but I knew two Unisys users who's use dated back to 1100 and Exec8
who are probably still running it. As a matter of fact I would not
be surprised if one of them was still running some of my code.
(although I will probably never know because they are not likely to
reveal anything about their operation!!)

The other one has tried "modernization" but as of the last time I
heard anything about it, it was not going to happen and was considered
somewhat impossible. :-)

Since there isn't a Convergent newsgroup
I just pushed a bunch of new updates to bitsavers for
CTOS/BTOS, and the NGEN and AWS including some of the
CTOS kernel code and drivers to

http://bitsavers.org/pdf/convergent
and
http://bitsavers.org/bits/Convergent

which applies to the B2x up through Supergen products

Both the ClearPath MCP and OS2200 systems are still being sold and
supported (well, after a fashion), but I suspect it's entirely a
replacement market at this point.

It's true that Unisys stopped making their own hardware, probably a
decade ago now, and everything runs on Intel processors. If you buy
hardware from Unisys now, it's standard Dell server boxes. While that's
a little sad, it simply got too expensive to design custom chips for the
size of the market, so Unisys effectively replaced their custom
microengines with a COTS microengine. After some creative re-engineering
of the firmware, they get quite impressive performance.

In addition to buying complete systems from Unisys, you can now license
just the firmware and system software and run it on your hardware,
either bare metal or virtualized under one of a couple of hypervisors.
You can also run it in the cloud, I think at least under AWS and Azure.

I believe that all of the remaining customers are facing big, difficult, expensive, risky migrations, and most probably have had five-year
replacement plans in place for the last 20 years.
