@kenshirriff @tubetime Wonderful restoration! Tangentially related, I read that the optional copier for the DEC VT52 used electrolysis to print onto damp paper using a helical electrode on a spinning drum. I found drawings and docs, but as far as I can tell, there are no working units that have been demonstrated on video anywhere. Would be really cool to see that in action! Very few terminals seem to have ’add water’ as a regular maintenance item 😄
