"Citadel was written in mid-December 1981 by CrT.
Miraculously, it ran three days unattended over
New Year's, collecting some remarkably favorable reactions.
During the months that it ran at 633-3282 (ODD-DATA),
Citadel became one of the more popular BBs in town, and
there was some disappointment when a hardware failure forced the system
down in February of 1982. But in January CrT had published the
source code in BDS C, putting it in the public domain."
"David Mitchell brought up the next incarnation of the Citadel
program in April of 1982, running on hardware provided by Richard
Knox. Called the Island Communication System, it is located on
Bainbridge Island in Puget Sound. ICS has about 30 regular users
and about 120 log entries. Newcomers find it easy to learn, and
often leave messages praising it. Some of the system's daily
users are in Boston."
"Citadel is descended from DandD.pas, an adventure game editor/driver.
It is arranged as a series of rooms, starting with the LOBBY. In each
room the user can read existing messages and leave more. There may be
up to 128 rooms in the current implementation. The system was brought
up with only one room, the LOBBY. Additional rooms were created by
the users, with room names appropriate to the topics covered."
"Citadel has had a checkered past. It first ran on a 64K Heath H89 with Magnolia CP/M."
