Atari Mania are on it again, with a Atari 400/800 prototype recovered by John Hardie. This time an Astrology program which was developed in 1982.

This is what Atari Mania posted about it on AtariAge’s forums:
“It seems Astrology was only listed in a single Atari catalog in late 1980 before being canned, although the author appears to have continued tweaking it until early 1982. Rather surprisingly, this title was written by John Dunn of VCS Superman fame and looks complete. If you want to play around with the program, you’ll find some easy-to-follow instructions written by John Hardie with the .atr file.”
