I've since got it working! :D Check it out here:    • Beamship update (or: how I got the IBM 497...  
Today we look at one of the most unique pieces in my collection; the IBM "beamship" 4978 keyboard. Essentially a beamspring battleship, this is one of those pieces I just HAD to get :D . There's a great amount of history behind these old IBM keyboards, of which I will present a little piece today. Part of its history, particularly the bits about "keyboard B" and "keyboard F", was made possible by some sterling work posted on Deskthority. Hope you enjoy the video! :D Maybe there will be a follow-up someday!

I'm Thomas and I do videos and reviews on mechanical keyboards ranging from the most sickening modern RGB gaming keyboards to vintage hardware relics, or sometimes keycaps or keyswitches ranging from Cherry MX to Alps SKCM to IBM buckling springs and anything in between.
