Centipede is a excellent BBS software package for the Commodore 128 computer system, taking advantage of the C128 capabilities. 

All Centipede files are freeware. The centfree package has all updates that were made to the program up to the end of development. The program is based on the Color 64/v128 BBS program but has it's own feel to it; that said, the BBS comes with templates to mimic other software packages such as Color64 and Image BBS.

Program must be run in C128 mode under 80 column. It has full CMD and REU support and works well with SD2IEC drives.
