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".
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 ...
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.
(It could be expanded to 512 steps.) It was limited to emulating calculator key presses and simple sequence branching. The programming was done by entering hexadecimal key codes. The combination of the MITS 7440 calculator and the programmer was not nearly as sophisticated as the HP 9830 calculator but $400 for both kits was a fraction of the ...

An electronic kit is a package of electrical components used to build an electronic device. Generally, kits are composed of electronic components, a circuit diagram (schematic), assembly instructions, and often a printed circuit board (PCB) or another type of prototyping board. There are two types of kits. Some build a single device or system.
