Burroughs was one of the first companies in the U.S. to successfully market the electronic calculator.  The first machines were built for Burroughs by Sharp in Japan.  These machines, identified as the C3000 line (C3100, C3200, C3300, C3350) were large, used Nixie tubes for the display, and were very expensive. 

The early machines were so fast as to amaze everyone who saw them, and at the same time, so slow that when the operator performed a difficult calculation, such as a square root (on the C3350), you could see the tubes flash as the calculation was under way. 

Burroughs built many models over the years of production, including a book keeping model with a moving printer. Never a market leader, these machines were very early on the market and were sold to replace the thousands of currently installed mechanical machines in Burroughs accounts.
