Burroughs Computer Micromodule (early 1960s)

An example of a Burroughs Micro-module encased in Lucite.

Burroughs competed with RCA, Photo-Circuits, IBM, ARMA, Hazeletine, Bendix and General Electric in the early 1960's for Micro-Module Circuit development to build the 1st generation of U.S. Army signal corp's new modular electronic communication equipment.

Item measures 3.5" tall x 3" wide x 1.25" deep.

Burroughs Integrated Circuit paperweight

Item #1005

This Lucite paperweight features an unfinished Integrated Circuit in DIP packaging from Burroughs.

It has a magnifier on top so you can view the exposed silicon die and wire bonding.

The first computers to use integrated circuits were the Burroughs B2500 and B3500 introduced back in 1968.
