Nostalgia Nerd has put together an entertaining video of Connecting a Commodore 64 to WIFI.
In this video he shows the hardware he used to achieve this, and various Bulletin Boards he used to interface with the Commodore 64.
Once this was a dream to be able to connect one's C64 to the outside world. Now it's a reality!
The WIFI Interface is available from Tim Harris, via Shareware Plus website.
Enjoy the video!
