Rockwell 350  
Written by Accutron on 2017-02-03  

Introduced in 1976, the Rockwell 350 is a rare example of Rockwell's narrow desktop scientific calculator product line. The 350 is a single-chip design with the same functionality as the more common 63R handheld scientific calculator. Rockwell scientific calculators have notoriously inaccurate transcendental functions, a key factor which sabotaged their entry into the scientific calculator market.
