Jens Schönfeld is working on a Internet connection for the Commodore C64. His proto-type is called "Onmyodo". The specifications at this moment are: 100MBit, TCP/IP Stack in Hardware, IRQs (low CPU usage) and a 16 kByte buffer. The Onmyodo can be "plugged" into the cartridge-port of the Commodore C64, but can also be used together with a MMC64, Retro Replay, MMC Replay and the Chameleon. You can follow the progress of this cartridge on the Forum64.de web page.
