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.
The TI-59 is an early programmable calculator, that was manufactured by Texas Instruments from 1977. It is the successor to the TI SR-52, quadrupling the number of "program steps" of storage, and adding "ROM Program Modules" (an insertable ROM chip, capable of holding 5000 program steps).
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 calculator can evaluate and simplify algebraic expressions symbolically. For example, entering x^2-4x+4 returns +. The answer is "prettyprinted" by default; that is, displayed as it would be written by hand (e.g. the aforementioned + rather than x^2-4x+4). The TI-89's abilities include:
Made in Japan, this was also the first calculator to use an LED display, the first hand-held calculator to use a single integrated circuit (then proclaimed as a "calculator on a chip"), the Mostek MK6010, and the first electronic calculator to run off replaceable batteries. Using four AA-size cells the LE-120A measures 4.9 by 2.8 by 0.9 inches ...
The operation and performance of the EL-8 are identical to its predecessor calculators, the QT-8D and QT-8B, because its logic circuits use the same set of four Rockwell-manufactured large-scale integrated circuits. [1] [2] [8] Likewise, its keyboard has the same layout, including the combined ×÷ key, [1] [2] and it also uses magnetic reed ...

The Gamma 3 was an early electronic vacuum-tube computer.It was designed by Compagnie des Machines Bull in Paris, France and released in 1952.. Originally designed as an electronic accelerator for electromechanical tabulating machines, similar to the IBM 604, it was gradually enhanced with new features and evolved into a first-generation stored program computer (Gamma AET, 1955, then ET, 1957).
