I had virtually no doc whatsoever. The unit I got working was from their test bench. It was a TD only model with front panel modified with extra push buttons for the Lat/Long version. I also got a few thousand of the unstuffed PC cards. At a guess, the GRI lookup tabvle would have been in the slave (Lat/Long) processor's ROM. In those days, I did not have a logic state analyzer, so know nothing more about the SW. I > have tried the obvious paths but had no help the UK dealer ceased trading > and filed earlier in the year.

No. My only Raytheon contact died about 3 years ago. :((. > I am in the process of turning this into a 10MHz locked source, (a couple > of > internal links) as it is not really too useful for Nav but it would be > nice > to get it working properly.
