[vcf-midatlantic] Apollo DSKY lights up again, despite faulty jumper

[Richard Cini]

Curious Mark does some great videos. My dad worked at Grumman on the Apollo lunar module, so it's a favorite topic of mine. He was a "thermal engineer" (even though his background was chemical engineering) so he was responsible for calculating the heat output of all of the devices/wiring to determine how much radiative cooling was needed in different circumstances.

    Curious Mark does it again: not only obtains genuine Apollo computer
    electro-luminescent panels but lights them up using the original relays!
    The relay logic is amazing: 5 relays generate 7 segment output including
    blanking! One hitch: a "Chinese-ium" Copper-Cladded-Aluminum jumper failed.
    Add that to the recent influx of faulty breadboards and it's a world of
    hurt for prototyping :-(
