Kevin Smallwood announced in the Facebook Apple II Enthusiasts forum that he intends to release the GBBSPro bulletin board system (along with ACOS and other related products) under the GPL. Kevin is the current owner of the GBBSPro product.
To my fellow Apple // fans. Tony Diaz and I are going to GPL the GbbsPro source code. Stay tuned. -Kevin Smallwood
Tony Diaz has a huge collection of GBBSPro/ACOS material, so in tandem, they will be releasing a literal treasure trove of Apple II telecommunications history and source code. We could even see a resurgence of interest in good ol’ fashioned Apple II BBS’ing, as several people have expressed their desire to update the code to support telnet access.
