Tact 2.2x Service

Although I do not have problems where can I get servicing or mods in the future. Also can I program without use of external computer.
You can go to the Tactaudiousersgroup forums and find a lot of information there. I'm not too familiar with the 2.2x but on my 2.2xp, it is possible to program without a computer but it's a LOT easier using it with a computer.
