Burroughs had three lines of mainframes:

  Small Systems (B1700/B1800/B1900)
  Medium Systems (B2x00/B3x00/B4x00)
  Large Systems (B5x00/B6x00/B7x00)

You're describing the small systems architecture which came along
in the 70's.

The B3500 (derived in part from the B300, which history includes the
electrodata 220) was the first system in the Medium Systems line
(a BCD machine addressed to the digit, designed to run COBOL).

The B5500 (follow on to the famous B5000) was the first system in
the large systems line (36-bit word, stack-based capability architecture;
buffer overflows are impossible!).

The Large systems lives on today in the Unisys Clearpath machines
(emulated on x86).

I worked on the medium systems MCP for 7 years, wrote the software
stack from power-on to system idle, and the data communications stack.
