Apollo Guidance Computer Part 28: real DSKY display works again after 50 years

Video Description

For the first time in about 50 years, we relight a real Apollo DSKY screen! And we can finally see the mythical glow in person. Much to our collective surprise, the screen is stupendously good - it could pass for a modern high resolution phone screen. We thank our sponsor *Samtec* for fabricating the NASA-spec connector pins, and of course Marcel for lending us just not one, but two of his precious displays.
