Some people seemed interested in checking out the custom keyboard polling routines I wrote for the CoCo from scratch. It does not depend on BASIC in any way. It does depend on a little bit of code being put inside an interrupt. It’s a work in progress and not complete by any means, but maybe it will help someone 🙂 Feel free to reach out with questions or suggestions using my Contact Info!
