Additional Notes:
Stands for "Dave's Own Citadel". Derived from Citadel/UX and used as the software for the ISCA BBS since the early 1990's. Can handle many connections (over a thousand). Used as the base code for a number of late 1990's derivatives.

An earlier version of DOC software is called DAVECODE. Derivative names include JayDOC and vDOC.
