Jason Scott is nearing completion on his 3-DVD documentary covering the history of the Bulletin Board System. He has conducted 200 interviews with many of the movers and shakers of the BBS scene, and it’s looking like the historical value of the project will be high. Be sure to check out the “Heroes” trailer. No doubt the Apple II will be mentioned (one such example is the RIPCO BBS, founded by Dr. Ripco in 1983 and run on an Apple II).
The site also contains a list of no less than 38 BBS programs released for the Apple II, with downloads! There is even mention of Litfal, an Apple IIGS BBS (perhaps the only IIGS specific BBS program).
