1976 1 ton Chevy truck: ZERO CHIPS
1979 Buick wagon: ZERO CHIPS
It started quite early. My 1987 Ford has an engine computer, digital speedo/odometer, digital tripminder, and digital keyless entry. At least I don’t have the electronic climate control, though even my mother’s 1984 Caddy had that. I have electronic cruise control but I took it apart and it’s all discrete components — transistors, but no chips.
