Hi everyone! Just found this site and i must say I like what i see. But now to my question: I'm getting into programming a bit for the lynx and have now come to the conclusion that i need/want a eprom cart to try out my demos on a real lynx. So, are there any available cart designs out there or do i have to take on the task designing one myself? Not that's it hard to do yourself but if it's readily available I see no idea to do it from scratch. Regards S-E Lindgren
