ISCABBS, also known as ISCA, is a bulletin board system ("BBS"), formerly based at the University of Iowa. Dave's own version of Citadel, an early branch of the Citadel/UX BBS software, was developed to run ISCA. Like most Citadels, the focus is almost entirely on conversation among users. History Governed by, and named for the Iowa Student Computer Association (ISCA), ISCABBS was started in 1989. Previously a computer conferencing software program entitled "Participate" made by Unison (Iowa students referred to it as "Parti") resided on the University of Iowa's Prime mainframe computer (running the Primos operating system) and was accessible to all University students. Precursors Many of the Parti users had migrated over from a student created BBS called BBS1 (circa 1985) which was accessed from its creator's personal account "astran" on the University of Iowa mainframe computer PrimeA. BBS1 was created and administered by Randy Frank (Mr Nybble) and David Richards (The Oracle) after they realized the popularity of their games and the hidden messaging system that was available from within the games. The original message system was concealed inside their "Draw Poker" game and allowed the creators the ability to convey progress and leave notes regarding current projects. The board was promoted across campus on flyers placed in computer labs. Users took on handles and developed a culture of their own with socialization being the main use of the board. A BBS1 user group was started and held infrequent meetings and offered T-shirts with a mystical picture and the caption "BBS1: A meeting of the minds". The software eventually was altered and passed around by a rogue sysop in a version known as "STEALTH" which could be compiled and executed on a user's own personal account. The main message system files were no longer safe or private once the general user population learned the directory names. The anonymity of a handle was proven to be non-existent and the cracked software allowed anybody to read any file they chose and track users back to their originating personal accounts. DOC creation Several student programmers began to create an improved code using the Citadel framework. As several developers were named "Dave" - including two key developers of the early software - it was coined "Dave's own version of " or "DOC" (Note: Often, this has been written "Daves' own version..." to note the plurality of Daves involved in the project).
