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:

1982.  This one is my favorite.

1983.  This is the one I remember the most:

APX Weekly Planner in Action

When the program loads you are presented with a menu of options. They are depicted in the screen shot below.  Note the program displays the date and day name:

Selecting add event.  After entering the date, it determines the day name as well.  Note in the example below that HOLIDAY is entered for the TYPE field.  None of the fields are limit restricted, however they are truncated to the internally defined size.  As such, HOLIDAY becomes H:

When selecting INQUIRY menu item, first select the Date, Time, and Person which can all have a wildcard.  Then select BROWSE or INQUIRY from the sub menu:

When select BROWSE from the INQUIRY sub menu, a list of matching records is presented in partial detail:

The APPOINTMENT LIST main menu option allows you to print a daily agenda on a full sheet of paper.  It can be blank or populated with data matching filter criteria you specify similar to the INQUIRY function:

The CALENDAR main menu option allows you to print a full month calendar on a full sheet of paper.  It can be blank or populated with data matching filter criteria you specify similar to the INQUIRY function:

Weekly Planner Version Update:

As noted in the podcast I have updated the software to version 1.1.  I am hosting it for now.  Rename the file from .ZIP to .ATR.  I can’t host files named as .ATR so it had to be renamed.


Once booted to BASIC prompt, enter: RUN “D:CALY2K”

The changes I made to the day name determination routine are covered in depth on my blog Unfinished Bitness at http://unfinishedbitness.info/2014/12/10/basic-what-day-is-it/


Change Summary

The following changes were applied to the original 1.0 code to allow Weekly Planner to work with dates from 2000 to 2099.  The 1.0 version would not work with dates beyond 1999.

  • Line 11: Added: REM UPDATED BY WADE RIPKOWSKI (2014)
  • Line 100: Changed version to 1.1, added (wr), spaced out word M E N U
  • Line 140: Set Instructions to lowercase (differentiate from Menu better), added one space before Press to properly center it
  • Line 420: Changed 19 to 20
  • Line 950: Changed 19 to 20
  • Lines 960,962,964: Removed
  • Line 966: Renumbered to 974
  • Lines 960,962,964,966,968,970,972: Added
  • Line 990: Changed to new month table values: 033614625035
  • Lines 991,992,994: Propercased Month and Day names

Changed Code

Since there is not an easy or practical way to print Inverse ATASCII characters on modern computers, captured printer output will have to do.  Here is an image of the code changes:
