This is dang cool! Thanks for all your contributions to all things vintage Blake!!! I would love to get my Apple //c on a BBS however, I see that the WiFi232 device is sold out. This is the first time I been to Paul Rickards' site. Does he by chance still build these devices? Doing some googling it looks like the device may be hard to come by now. I see various things on eBay... anything you might recommend from eBay? Thanks much for the post!
BTW, I've always been a big fan of the BYTECellar! 
@amigakit - You guyz sell any WiFi232 devices? 
Many thanks. Glad you have enjoyed!
The //c (and some other systems I've BBSed with,
like the eMate 300) is going from serial port to USB-to-serial adapter into a Raspberry Pi which serves as a bridge. You can then telnet from the Pi out to a BBS, with the //c or whatever serving as a regular UNIX serial terminal to the Pi. It's as if the //c is another Terminal / Shell window, simply. So that's one easy way to go.
Paul is no longer making WiFi232s, but I have listed
a number of other devices that are being made that would fit the bill, likely.
Good luck!
