"A very simple but powerful Bulleting Board System. It's based on LazyBBS source code but I have made some changes (SCC serial ports support - so Modem2 and Serial2 work) and enhancements. The JoyBBS is fully Fidonet compatible and can work together with AtariST mailer (Semper/Binkley) and Fido mail tosser (Jetmail/IOSmail)." - Petr Stehlik
