I'm working on my 8 bit TTL computer (https://hackaday.io/project/162659-8-bit-breadboard-cpu) and have just received a sack of 3 pole switches I ordered. I'm using them to run the control signals for testing all modules working together. ...
I'm not going to mention the brand incase there's any issues with that but a friend recently gave me a beat to hell electric longboard without the charger or controller. I'm not too worried about the charger since I'm probably going to open up the batteries...
Working on my 8 bit TTL CPU. I've got a version of IRQ working. When IRQ is pulled low, it loads the IRQ instruction (FF) into the instruction register after the current instruction is finished. I am trying to figure out the simplest...
