Welcome to the Atari 1090 Expansion Projects

Central Hub

 

 


 

It is the intention of this website to help bring together as much technical knowledge on the Atari PBI (Parallel Bus Interface) and its XE version the ECI (Enhanced Cartridge Interface) to allow those interested in creating PBI/ECI based upgrades for the XL/XE lines of computers and also with modifications, an Atari 800 can be PBI equipped.
