Jim Johnson writes "I am the author of that system. The package was known as the "Deadlock BBS Construction Kit". We have not supported or developed it for many years, it faded away in 1986-7. As a bit of history: The software was written in compiled basic and the source code was so large that it could only be edited on a Commodore 128. The company was a 2 man operation, myself, Jim Johnson, and my partner, Kevin Masucci. We operated out of our homes and sold the system nationwide via PC magazines."
