Hi all,
As I am currently also working on a C64 project, I keep having an eye open for new expansions to my C64.
Very recently I got aware of a new cartridge for the C64 named "BackBit".
The homepage of the expansions is here. And of course they have a shop. They do also have a forum, of course.
Below please find an overview that I grabbed from ebay, actually. Seems pretty advanced.
