In the late 1970s, Raytheon farmed out their small boat LORAN receivers to a New Hampshire company, Appelco. They made 8085 based LORAN receivers w/ LED readout of time differences. Later, Appelco produced an upgraded version with a daughter board, also with an 8085, that took the data from the mother board and converted it to Lat/Long readout. Obviously, that daughter board had the needed SW in its ROM. Mine certainly worked on the bench and gave consistent positions to within about 100 feet. The model number was LC....? I'm not certain there were many produced, but it might be worth a look. BTW, Raytheon places a muli-million dollar order w/ Appelco, then pulled the plug on a technicality. Appelco went bust. I got the stuff at their bankrupcy auction. The down side is I cannot put my hands on it any time soon.
