Calculators became available in the early 70's, soon after the integrates circuits, and several companies were competing with each other for a share of this market. Texas Instruments was one of the bigger companies producing calculators. With RCL it is possible to recreate the TI calculators, strating with the Ti59e, with 960 program steps and a persistant memory (a combination of the the Ti58C and the Ti59). RCL offers any person interested in the ancient ones in calculators (more specific: TI calculators) an option to have your old calculator under your control again. Looking for user manuals? go to http://www.rskey.org/CMS/index.php/the-library/12 (The site owner does a great job at preserving the history and the documentation of calculators of the period.) RCL is targetting developers interested in applying the Von Neumann architecture and attributed grammars and developers with a need to do complex calculations in their applciacation.
