Very short note announcing that Rockwell intends to shut down its Unicom Systems, Inc. calculator division. Unicom Systems, Inc. was acquired by Rockwell from American Micro-systems, Inc. (AMI) in September of 1972, and served as Rockwell's calcualtor manufacturing and distribution arm. Initially the calculators that Unicom sold before becoming fully integrated into Rockwell were sold under the Unicom brand name, but used chips from Unicom's former owner, AMI. Rockwell mandated that future calcualtors use its own Large Scale Integration calculator ICs and designs using Rockwell's chips soon began to be sold under the Unicom brand name, with the calculators with AMI chips in them being phased out. In time, all Unicom-badged calculators utilized Rockwell's calculator ICs exclusively. Due to the intense competition in the electronic calculator marketplace in the mid-1970's, as well as a general down-turn in the global economy during the period, it was decided that Rockwell did not need the overhead of Unicom, and shut down the division. Parts of Unicom were integrated into Rockwell, manufacturing and selling calcualtors under the Rockwell name. This action reduced costs significantly, allowing Rockwell to stave off the losses that it had begun to incur in its calculator business.
