all my latest files are now released. The changes are from 2019-2020, when I did the video series and tested it on real hardware using a xilinx nexys 2 dev board, and a custom built test cart with many unit tests testing the logic and functionality like timers. I've kept these changes close to my heart in hope of trying them myself on a the vhdl6526 pcb. Then came other projects doing the same thing. https://youtu.be/CbxQUAu8e3s?si=uPUL7sAFPG0KeHP3

Now Dag Lem has released a reDIP-CIA PCB. I wonder if I can convert my VHDL files to work on it. https://github.com/daglem/reDIP-CIA https://theoasisbbs.com/revolutionizing-legacy-systems-the-redip-cia-fpga-replacement-board/
