The Lynx Gaming Sharing System (LGSS) was developed by Harry Dodgson. This system allowed a game cartridge to be shared between multiple Lynx systems via a ComLynx connection. Specifications for LGSS have been published in the past but are not longer available and all attempts to get a hold of them from Harry have been met with silence. Unfortunately it looks like LGSS is a dead technology.
To get LGSS to work, a game that supported it was required, then in addition a special LGSS cartridge was also required on every other Lynx system that was connected via ComLynx and wanted to share the game. Here is how it worked:
The only game that supported LGSS was a homebrew title, Lynx Othello.
