“BattleBots” premiered on Comedy Central in, I think it was, 2000. Greg Munson: Probably the biggest is battery technology. What are the biggest changes you’ve seen, technology-wise, over 20 years or so? Sears and RadioShack were among the companies that would private-label subsequent Bowmar models. It listed for US $240, or about $1,400 in today’s dollars.īowmar soon found several customers who wanted to resell the 901B under their own names, among them Craig (which called it the model 4501) and Commodore (the C110). The 3.1- by 5.2- by 1.5-inch calculator was introduced in 1971 or 1972 (sources disagree).

Handy Guide: Early Bowmar calculators came with explicit instructions on the back, aimed at users who had almost certainly never used an electronic calculator before.
Could Bowmar succeed with a handheld calculator that used LED displays? In 1970, the company decided to find out. The very earliest battery-powered calculators, which appeared in Japan around 1970 from Canon, Sharp, and Sanyo, used unwieldy fluorescent or gas-discharge displays, or even tiny thermal-paper printers. One possible application would have been in the compact calculators that had only recently begun to appear, but Bowmar was having trouble cracking that new and growing market. They were novel, but at the time they were also small and faint, and there weren’t many commercial uses for them. Several other companies followed Monsanto into the market, among them Bowmar/ALI, then a tiny defense-industry subcontractor in Acton, Mass.Īt first, all Bowmar/ALI intended to do was make and sell LED displays. In 1968, Monsanto created the first numeric LED display cheap enough to be used in consumer products.

The creation of the Bowmar Brain was a desperation move.
