The source code for three text adventures from Phoenix Software has been released by the original programmer, Paul Berker. Adventure in Time (1981), Birth of the Phoenix (1981), and Queen of Phobos (1982) were published for both Apple II and Atari, with source code for both platforms now available from the AtariAge forum.

These releases were coordinated by Kevin Savetz, co-host of the ANTIC podcast. His interview with Berker was released on Nov 19, 2016, as episode #254 of ANTIC.
