In the retro-computing world (Oric-1/Atmos) we are using the PicoW as a way to get our old machines on the Internet, not by implementing USB-CDC drivers on the old machines, but by having the PicoW imitate an old-school modem interface, albeit one that 'dials in' to a web site address instead of another modem ..

It's pretty cool, I have to say - especially for us old Oric folks, who never did quite get a full BBS ecosystem for these machines, unlike others. Its on like donkey kong now though, thanks to wonderful PicoW projects like this!
