Relay-based AND and NAND gates
Relay-based AND and NAND gates 1.0 for Mac was available to download from the developer's website when we last checked. We cannot confirm if there is a free download of this app available.
According to the results of the Google Safe Browsing check, the developer's site is safe. Despite this, we recommend checking the downloaded files with any free antivirus software. The actual developer of this free software for Mac is University of Hamburg. The software is categorized as Education Tools.
From the developer:
This applet demonstrates a three-input logical AND and a two-input logical NAND built with relays.
Click the input switches or type the ('a','b','c') and ('d','e') bindkeys to control the circuit and watch the behavior.
The upper circuit uses three relays, with the coil of each relay connected to one input and ground. Therefore, the relays will activate whenever their corresponding input is driven to a (strong) high level.
You may want to check out more software for Mac, such as Laura Jones and the Gates of Good and Evil, Lara Gates: The Lost Talisman or The Treasures of Mystery Island 2. The Gates of Fate, which might be similar to Relay-based AND and NAND gates.
