The instruction set, hardware architecture and microcode of the B3-34 defined the standard of the later Soviet programmable hand-held and office-desk calculators: MK-61, MK-52, MK-54 , MK-56 . Model numbers do not follow any special order: MK-54 is a slightly upgraded version of B3-34 and MK-56 is its desktop copy, while MK-61 and MK-52 are ...
Sharp QT-8D Micro Compet front view. The Sharp QT-8D Micro Compet, a small electronic desktop calculator, was the first mass-produced calculator to have its logic circuitry entirely implemented with LSI (large-scale integration) integrated circuits (ICs) based on MOS (metal-oxide-semiconductor) technology.
dc (desk calculator) is a cross-platform reverse-Polish calculator which supports arbitrary-precision arithmetic. [1] It was written by Lorinda Cherry and Robert Morris at Bell Labs. [2] It is one of the oldest Unix utilities, preceding even the invention of the C programming language. Like other utilities of that vintage, it has a powerful set ...
Smaller programmable model with programs up to 49 steps. Version HP-25C was first calculator with "continuous memory". HP-27S: 1988 The first HP pocket calculator to use algebraic notation only rather than RPN. It was a "do all" calculator that included algebraic solver like the HP-18C, statistical, probability and time/value of money ...
dc: "Desktop Calculator" arbitrary-precision RPN calculator that comes standard on most Unix-like systems. KCalc, Linux based scientific calculator; Maxima: a computer algebra system which bignum integers are directly inherited from its implementation language Common Lisp. In addition, it supports arbitrary-precision floating-point numbers ...
The tube technology of the ANITA was superseded in June 1963 by the U.S. manufactured Friden EC-130, which had an all-transistor design, a stack of four 13-digit numbers displayed on a 5-inch (13 cm) cathode-ray tube (CRT), and introduced Reverse Polish Notation (RPN) to the calculator market for a price of $2200, which was about three times ...
