  • Big Old List of *EVERY* Custom Amiga Chip and Chipset Name I Could Find (20 Feb 24)

    Over the years I have been to THOUSANDS of sites and I never found one that had ALL the chips in one place. This is MY attempt to create a quick and dirty list that does. And yes it contains LOTS of mistakes but it's a start right?

    Feel free to make comments and I will be more than happy to update this WORK IN PROGRESS. Enjoy!
