Want to know the number of devices that can fit into the palm of your hand? Get your mind out of the gutter – we’re talking electronics here, and this DIY portable Atari 2600 fits the bill nicely thanks to efforts by one who calls himself “The Longhorn Engineer”. He took a different route by designing his own circuit board in a new hardware initiative dubbed Project Unity. You will find all the relevant details within to get your game on, including video, audio, controller buttons, paddle control and a cartridge connector. This system was specially developed to use cartridges instead of as a game jukebox, so don’t bother looking for ROMs to store within.
