Commodore 64 IRQ LED
Wouldn't it be nice if your fancy old breadbin-styled Commodore 64 computer could tell you more about what it is doing? Well, now you can have the power LED change to green when it is performing I/O operations (IRQ-line is being used). Amazing stuff, it really needs to be seen to believed so get yours now! Not really necessary though, it is however a fun modification to do with just a handful of parts!
Check out the github-repository for BOM and instructions.
