Hopefully we can get the teleprinter to print. But first we'll need to do some maintenance. A rubber roller turned to goo that was soaked up by the paper. (Sorry, no photo.) So we'll need to replace that. Stay tuned... 12/13

@kenshirriff Incredible stuff! Please keep us posted on your progress!

Did that type of print head/drum work by rotating to present a facet with the desired symbol in the desired place then transferring it to paper via a ribbon and hammer? If so, that is wild.

NASA must've decided it was worth the weight budget to ship up this incredibly device. The frame looks like cast iron! I bet the symbol drum weighs a few kilograms by itself.

@kenshirriff Most of the space shuttle was early to mid 1970s technology, like this. It was meant to fly before 1978 & save SkyLab. Dot matrix was not around, except for some heat sense printers. Daisy wheels were new, leading edge technology. Dot matrix was new, low quality & slower. Definitely didn't want mis-reading because of low print quality. Standard spec's will have required line printers. With a Motorola 6800 CPU, this was a modern printer for the shuttle.
Rubber deterioration is the bane of all old equipment, including cars & chainsaws, from personal experience.
