Who are you/where are you: We are Atari enthusiasts just like you. We are located in Toronto, Ontario, Canada.  We see the SIO2PC as the most useful upgrade to date for the 8 bit Ataris. However we also noticed that there were not too many choices when it comes to buying this hardware. Basically only one supplier in North America and only one software to support it. We believe in diversity and choice. So we decided to give fellow Atarians a second alternative, one that gives them the option to pick and choose the features they want and customize the hardware to their needs instead of picking a standard issue interface off the shelf.
