S1E5 APX Decision Maker – Supplement

 

This episode features Decision Maker, originally released in 1981 by Color Computer Concepts through APX.  It was written by James L Bruun.  This program for the Atari 8 bit line of computers was written in BASIC and released on cassette and diskette.  Absolute initial pricing was hard to discern as different sources listed different amounts at the time of release.

Many Faces of APX

APX, Atari Program Exchange, was a software distribution model run by Atari between 1981 and 1984.  It was similar to shareware in that it allowed users to write and sell software as commercial titles, but it allowed for a central point of sale and distribution.  I like to think of it as a very early App store.

1981.  Similar to the Atari Connection magazine logo:

  1. Hi Wade,

    I really enjoy the podcast. I wasn’t an Atari owner but I really enjoy listening to your shows.

    It would be helpful to me (and possibly others) if the audio file names contained the shows name or initials. Perhaps just inverse or atascii added to the file name. ( maybe invat_s1e5.mp3) Thanks for all your hard work!

    1. I’m glad your enjoying the show. Thanks for the suggestion on the filenames, I hadn’t thought about management outside of iTunes. I will make a change starting next episode (S1E7). Thanks!
