(j3.2006) (SC22WG5.4208) RE: RE: 43 Fortran compilers

[Van Snyder]

According to
http://www.spiritus-temporis.com/univac/history-and-structure.html,
Remington Rand bought the Eckert Mauchly Computer Corporation in 1950,
producing the Univac I in 1951.  The article doesn't say when Remington
Rand bought Engineering Research Associates, but it does say that it
merged its tabulating machine division (which had been the Electronic
Computer Corporation subsidiary of American Totalizer -- which made
horse race track tote boards), its Univac "business" computer division,
and its Engineering Research Associates "scientific" computer division
(where 1101 originated), into a single division under the "Univac" name,
in 1953 or 1954.  Remington Rand merged with Sperry Corporation in 1955,
with Douglas MacArthur as head of the company.  The Univac division of
Remington Rand was renamed Sperry Univac.

By 1978 Sperry Rand was a disharmonious old-fashioned conglomerate
making computers, typewriters, furniture, hay balers, manure spreaders,
gyroscopes, avionics, radar and electric razors.  They decided to
concentrate on computing interests and unrelated divisions were sold.
They dropped "Rand" from the name and reverted back to Sperry
Corporation.

In 1983 Sperry Corporation discontinued the name Univac for their
products, calling them Sperry 1100 and Sperry 2200.

In 1986 Sperry Corporation merged with Burroughs Corporation to become
Unisys.

It looks like they only make one system, perhaps in several varieties.
It's called ClearPath.  I've seen it with "IX" and "Dorado" and "Libra"
and "MCP" stuck on the end.  Everything in the various machines is
common except the actual CPUs.  One provides 1100/2200 compatibility (36
bit words) through ASICs and runs OS/2200.  Another provides Burroughs
large system compatibility (again through ASICs) and runs MCP.  At least
some systems have Xeon (and briefly they had Itanium) processors and run
Linux.  They claim the forte of OS 2200 is security.  They also claim a
single system can run Windows, Linux, OS 2200 and MCP concurrently --
probably with Univac, Burroughs, and Intel CPUs all in one box.
Probably a big box, since Dorado systems start at $200,000.
