This tool emulates a fictitious CDC8612 CPU based loosely on the 1970's CDC-6500 supercomputer.

This tools allows you to create logic gates by laying out PMOS and NMOS transistors in a breadboard-style user interface.

This is an emulator for the E6B analog trigonometry computer that pilots use to compute windo correction angle for a particular wind speed, airspeed, and desired ground track. It was developed in the late 1930s and is still a big part of private pilot training when preparting for cross country flights.

This tool allows the user to place and connect gates and other digital logic components like half-adders and latches to create andemulate simple electronic digital circuits.

This tool allows uers to create simple VLSI layouts by 'painting' metal and silicon traces to create digital cicuits suitable for manufacture by photo lithography. Thsi tool also simulates the circuits after they are built. The tool s a simplified version of the Magic VLSI layout tool.

This is a simple online slide rule capable of demonstration multiplication using addition of logarithms.

This tool allows the user to enter WASM code (in WAT format), aseemble the code, look at the resulting maching code and then execute the resulting WASM and see the output from the program.
