The otherwise binary Wang VS machine supported a 64-bit decimal floating-point format in 1977. [2] The Motorola 68881 supported a format with 17 digits of mantissa and 3 of exponent in 1984, with the floating-point support library for the Motorola 68040 processor providing a compatible 96-bit decimal floating-point storage format in 1990.

The first American-made pocket-sized calculator, the Bowmar 901B (popularly termed The Bowmar Brain), measuring 5.2 by 3.0 by 1.5 inches (132 mm × 76 mm × 38 mm), came out in the Autumn of 1971, with four functions and an eight-digit red LED display, for US$240, while in August 1972 the four-function Sinclair Executive became the first ...
Despite its simplicity, it can handle complex tasks typical of high-performance computers. MIX allows programming in both binary and decimal, with software emulators available for both models. MMIX, which superseded MIX, is a 64-bit RISC instruction set architecture, modernized for teaching contemporary computer architecture.
Codon is a language with an ahead-of-time (AOT) compiler, that (AOT) compiles a statically-typed Python-like language with "syntax and semantics are nearly identical to Python's, there are some notable differences" [148] e.g. it uses 64-bit machine integers, for speed, not arbitrary like Python, and it claims speedups over CPython are usually ...
A 1 MHz chip used in KIM-1 and other single board computers in the mid-1970s. 6502A A 1.5 MHz chip used in Asteroids Deluxe and at 2 MHz in the BBC Micro: 6502B Version of the 6502 capable of running at a maximum speed of 3 MHz instead of 2 MHz. The B was used in both the Apple III and early Atari 8-bit computers, each running at ~1.8 MHz. [c ...
