After the first program load, you need to insert the data disk.  Make sure its either been used before, or if it’s blank make sure it’s formatted:

Family Tree Load 1

Family Tree Load 2


After the data disk is loaded, the bottom of the tree is displayed.  In this case, an empty data set:

Family Tree Cht 1


Defining the bottom most person or “acorn”.  Acorn is a term I dubbed for the nodes in the tree, and not endorsed by the manual.  This is who the tree is for:

Family Tree Cht 2


Add Person

Defining the father (or any person for that matter) is a four step process:

Family Tree Cht 3 1

Family Tree Cht 3 2

Family Tree Cht 3 3

Family Tree Cht 3 4



This is the only way to save:

Family Tree Cht 4

Family Tree Cht 5


Extended Generation Edit

Moving one of the grandparent “acorns” to the base to work on further extensions of the tree:

The Family Tree uses Atari DOS 2.0.  The contents of the disk can be seen in this screenshot:

Family Tree Files

The files are:

  • DOS.SYS is Atari DOS 2.0s.
  • DUP.SYS is Atari DOS interface.
  • AUTORUN.SYS is the autoloader for the BASIC program file TREE.
  • TREE.PIC is the tree picture used as the interface.
  • A1.DAT is a data file that has the authors family tree present.

On a new empty data disk, only the data files are present:
