Hi Chad / readers,
I am not sure either, but this is what I know for sure.
Before the merger SPERRY/Burroughs, Burroughs had a systems line
but I do not know anything about those. SPERRY had the 1100-series;
I programmed even assembly (MASM-1100) on those fine main frames.
After the merger, so now it is UNISYS, the 2200 came available.
It has a smaller footprint, lower power consumption, but is
compatible with the 1100. Compiled/assmbled programs from the 1100
run on the 2200 without any re-compilation.
I worked with the 1100 from 1990 to 1995, unitl I left the company.
Never had any contact to 1100's afterward.
Sometimes I miss the "@ASG,T" and all other demand-mode commands
and the assembly language ... EXEC was (is?) a real good OS.
- Henk.

I vagely remember that the 2200 line was called the "A-series", as
there was also a "B-series" as a result of the merger of SPERRY and
BURROUGHS to the new UNISYS.
But, I am not sure. I left that company (and fine 1100) in 1990 ...

I'm not sure 100% sure either, but I recall differently (but
only from
reading). The 2200 was the Sperry's mainframe contribution
to Unisys.
The A-Series was from the Burroughs side.
I don't remember hearing about any "B-Series". Do you mean
the systems
that ran Btos..... I think that's what it was called. I don't think
they were mainframe class, but I'm not sure on that either :-)
