IBM and Compatibles: DOS: GSBBS
Author: Shadow Lord
Additional Notes:
"GSBBS version 3.0 is probably the most versatile and enjoyable Bulletin Board software for the IBM PC/XT or AT models. Many years in writing, development, and online testing, GSBBS is the ideal alternative for prospective system operators who like the FidoNet system of echoed message bases but are not satisfied with the limited programs generally used to access the network, such as Opus."
