In the 1980s, Chrysler made an electronic ignition system which used an
1802. It was fitted to all Volvos with mechanical fuel injection and
catalytic converters sold in the US. Also the early versions of the
Bosch Motronic fuel injection/electronic ignition system used 1802s. I
believe the reason for using the 1802 was that it was more immune to
interference than NMOS parts.
Around 1982-1983 Bosch switched to the 8049.

I don't
think I ever did anything remotely interesting with it, but it's
still a neat toy.
It's a great toy. ...etc...

Nice. I had no idea that the 1802 appeared in automobiles. I was
formerly only aware of satellites and space probes.
My involvement with automobiles at the fuel-injection level has been
limited to air-cooled Volkswagens, so I doubt I'll ever encounter an
1802 under the hood of anything I'm likely to be repairing.
