    Default Colors of Vintage IC's

    I've seen black(duh), white/gold ceramic, purple/gold ceramic, blue, and yellow. What other colors did they come in and why?
    Wanted: Any old clunky 286-P1 machine that has some kind of working battery or replaceable with off the shelf parts. Preferred: 10+lbs 386 machines.

    Different materials were chosen for good reasons. Ceramic (usually white or purplish) was better at dissipating heat than plastic. Gold is a superior conductor and good for high performance applications.

    Resistor networks, though not strictly ICS, were often colored blue, yellow or red.

    I have some gray 2102 memory chips that are quite old. I don't know why they are gray.
