The 1802 was an interesting little beast. Many years ago I was a Harris NJ plant
that used to be owned by RCA and was the home of the developers of the 1802. One
of the Voyagers was close to its last planetary encounter. It had already been a
few years since Voyager had been launched. At lunch one day an elder gentleman
came along and his story was that he looked forward to retirement as soon as
Voyager passed its last Planet. Seems that he had taped out the 1802 IC and NASA
needed him to be available if needed. Those were the days that processors had
real signal and power tracks in them also one of the reasons besides essentially
no power consumption that the 1802 was a favored early space computer.
