Z80 computer with toggle switches as input

We normally call “computer” a device which has processor, display and input like keyboard and mouse. But this them cover much more than personal computer. Single microcontroller chip can be called a computer because it’s main purpose is to compute something. This following project definitelly breaks the understanding on how computer should look like. Jim MacArthur shared pretty interesting concept of computer. He used Zilog Z80 microprocessor which has only 256 bytes of ram. Then he built interesting user interface that consists of toggle switches as input and LED bards as visual feedback.

Computer can be programmed with toggle switches where you can store commands and data in different memory addresses and then run same program by pushing clock button. There isn’t much practical use of it, but can be great tool to learn how processors work. Computer is built in laser cut plywood case which comes with rotary handle connected clocking mechanism. So by cranking it you can run program. It think it might serve as nerdy wearable accessory.
