Naah.. there will be pirated copies all over the universe in short order.
The state of the Big Trak is good. It's actually the platform for an autonomous vacuum cleaner project. I am using it to test sensors and get the programming squared away.
I wish I knew someone with a trashed Rainbow I could examine to guide me here or a Rexair serviceman who could hook me up with parts or let me see some exploded diagrams of the various models. Damn. They guard this stuff like it's nuclear secrets or something!
(Vacuum cleaners ain't my specialty, so I need allot of help in this department.)
