Formosa BBS
Formosa BBS (or NSYSU Formosa BBS) was one of the earliest, if not the first, telnet-based Bulletin board systems (BBS) to have Chinese language capability.  Work used from creating Formosa was combined with the open source Pirate BBS to create Eagle BBS from which the more user friendly Phoenix BBS was derived.  The open source Phoenix BBS was the parent of the widely used Firebird BBS and Maple BBS.

Formosa BBS
Formosa BBS established in October 1992 by Professor Nien-Hsing Chen of the National Sun Yat-sen University (NSYSU), was one of the earliest, if not the first, telnet-based Bulletin board systems (BBS) to have Chinese language capability.  The objective was to provide a means for professors, universities and students to communicate.

Eagle BBS 
In developing the Formosa BBS Chinese language interface Professor Chen used code from the open source Pirate BBS.  The developed code was returned to the Pirate BBS developers who created Eagle BBS as an open source BBS with a Chinese language interface.

Phoenix BBS 
Phoenix BBS was development of the Eagle BBS but incorporated a more user-friendly interface.

Firebird BBS 
Firebird BBS is one of two main telnet-based Bulletin board systems developed in Taiwan. It is also gained popularity in mainland China and was adopted by most sites there. Several derived BBS systems are based on its source code.  Some popular sites like SMTH BBS and HKiBBS are using the derived system of the Firebird.

Maple BBS 
Maple BBS is one of two main telnet-based Bulletin board systems developed in Taiwan, the other being  Firebird BBS.   IN Taiwan most BBS adopted Maple or its descendants in preference to Firebird BBS.  Several BBS systems are based on its source code. In Taiwan Maple BBS and its descendants generally gained market share from FireBird BBS.
