OT: Has anybody used the "ABC" AVR Basic Controller?

I recently acquired an AVR Basic Microcontroller "Maxi Board" which is an applicaton of the AVR 90S8535 MCU with a number of potentially useful features. However, it's got the worst set of documents that I've ever seen published for what should be a substantial product of its type. It has errors, it lacks vital description elements, e.g. which CPU pin drives which connector pin, etc. They lon longer, however, make the board I have, and, as a result, I'm hoping that the "real" doc's have simply been replaced by the ones for their current model. I'm certainly not going to buy one of their current products if this one's doc is representative of what they produce. Any info directrly acquired from dealing with the board mfg's (Investment Technologies, in AU) that you can share would be appreciated. thanks, Dick
