I'm sure glad you are preserving these wondrous old machines.

Here's an appropriate Mark Twain quote.

"All the other wonderful inventions of the human brain sink pretty nearly
into commonplaces contrasted with this awful mechanical miracle.
Telephones, telegraphs, locomotives, cotton-gins, sewing-machines, Babbage
calculators, Jacquard looms, perfecting presses, all mere toys,
simplicities!"
 	Mark Twain, 1889 (writing about the Paige typesetter)
