It is assumed to be some kind of dongle for the 6809 software. In the early 1980's, there was a group called ISPUG (International SuperPET User's Group) that published the "SuperPET Gazette" newsletter. A few people in that group were reverse engineering the Waterloo software. I managed to contact one of them and asked him about the 6702. He was not clear on its function but agreed it's probably a dongle and remembered finding references to it in some floating point routines. I recently contacted Greg James of visual6502.org and offered him a 6702 for die shots. I heard back from him yesterday and he accepted. I will send it to him and hopefully we can get closer to solving the mystery.
