PDF version of the cleaned-up documentation to Ed Churnside’s incredible Dragon’s Toolkit and Integrated Library (TAIL) for Atari 8-bit computers. As a young programmer, this was easily my favorite and most useful purchase; sadly, the resource is essentially unknown today.
The toolkit included a library of machine language routines that make adventure game creation in BASIC possible. Most of the documentation is over use of the ML routines and associated tools themselves, while Part IV includes a wealth of tips and tricks for managing the logistics of game implementation.
