List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE. The following table is split into two groups based on whether it has a graphical visual interface or not.
PL8000 - The PL8000 is a 3.2 lb white calculator with a 2 color backlit 14-digit 17mm dot matrix display. It can do cost/sell/margin, currency, installment loans and time calculations and it has a 8 lines-per-second (lps) thermal printer which prints on 2 1/4" thermal paper. It includes PROMPT LOGIC™ and a HELP key which guides the user with ...
The circuit module design and packaging was also used for the IBM 650, the world's first mass-produced computer and a very popular computer during the 1960s. An all-transistor version of the 604 was built and demonstrated in October 1954. Although it used over 2200 transistors as opposed to 1250 tubes in the original, it occupied only about ...
The Victor 3900 is the first electronic calculator to have been built entirely of integrated circuits (ICs). [1] [2] For its era, the 3900 is extremely advanced; it has a 4-inch (100 mm) cathode ray tube screen to produce a 5-line display, has separate memory for storing three intermediate results, supports numerical rounding, and is still "smaller than a typewriter".
The assembly kit consisted of eight groups of components, plus a carry case. [13] The build time was advertised as being around three hours, and required a soldering iron and a pair of cutters. [ 13 ] [ 14 ] In January 1975, the kit was available for US$49.95 , half the price at the time of introduction a year earlier, [ 13 ] and in December ...
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 ...
The computer was assembled on a single double-sided printed circuit board. The board was supplied in a light cardboard sleeve that appeared to be an LP record sleeve, having the words "Dick Smith Super 80 Microcomputer Kit Printed Circuit Board" and the part number "Cat H-8402" printed along the spine.
The Sinclair Cambridge was a pocket-sized calculator introduced in August 1973 by Sinclair Radionics. It was available both in kit form to be assembled by the purchaser, or assembled prior to purchase. The range ultimately comprised seven models, the original "four-function" Cambridge – which carried out the four basic mathematical functions ...
