There are two different hardware add-ons which provide a "computer- 
network" (two or more Ataris linked together). Thus, there is software 
that supports either one or the other hardware (namely Gamelink-1 or
Gamelink-2). The following software supports the networking hardware:

- Gamelink-1 (by Dataque): 
  - info-text about GL-1 and where to buy it, by Dataque;
  - Tic-Tac-Two by J.Potter/Dataque, a tic-tac-toe clone; 
  - Modem-Battleships, patched by Rick Detlefsen for Gamelink-1;

- Gamelink-2 / Multilink (by Dataque & Bewesoft):
  - Maze of Agdagon demo (1 player only) by Dataque;
  - Maze of Agdagon (full version, 2-8 players) by Dataque;
  - Multi-Dash (2-8 players, XL/XE only) by Bewesoft;
  - Multi-Race (2-16 players, XL/XE only) by Bewesoft;
  - Multi-Worms (2-8 or 2-16? players, XL/XE only) by Bewesoft;
  - "starter-kit" module to use in your own networking-games by Bewesoft
    (free use of this module is granted by Bewesoft/Jiri Bernasek);
