      I think it’s entirely possible, however, that the /? key already existed by the time Electromatic got there. Would require sifting through 1900–1920 typewriters carefully.

      The other thing that would really help would be a clearer picture of the 1930 pre-stencil Electromatic. It *looks* like ? is already paired with / there, which would argue against the uniform-velocity motivationpic.twitter.com/84JmTL6Kfg

      Not sure what you mean by “pre-stencil” and how it connects. Is that a different machine than this?https://twitter.com/mwichary/status/1037571972291391489 …

      A few decades later, a small company called Electromatic worked on an electric typewriter. An electric typewriter helps you in swinging the typebars – you need to touch the key gently, and the electrically-powered rolling bar does the rest of the work. pic.twitter.com/ZUx9o4SrxG

      Yes. What I mean is that there were two versions of the Electromatic. The July, 1930 model had "manual" pairing, with " and ' over 2 and 8. The October, 1931 model introduced "electric" pairing. These are in the documents that I lent you that you scanned for me.

      The first version didn't care about uniform velocity for each key. They introduced the uniform velocity in the second model to avoid cutting through mimeograph stencils

      Wait, how do you know this? Just from the scans you shared with me? I don’t see all the info there, but maybe I’m not smart enough to infer.

      I may have misread it all this time, or there may be another source that I've forgotten after 20 years. The variable-force paragraph is in the 1931 description, but I have no proof that they didn't also do it in 1930. The 1930 *does* have an @/¢ key instead of '/" thoughpic.twitter.com/8xzdtVsDp4

      The 1929 patent https://patentimages.storage.googleapis.com/fa/19/23/cfd441637a2027/US1818200.pdf … just refers to varying velocity with Shift, not by individual key

      I’d love to get to know more about this machine. I am attempting to interlibrary some stuff and contact Rochester Museum Science Center to see if they know anything.

          Do you know much about Electromatic Executive with (somewhat) proportional fonts?pic.twitter.com/kypNbTKaQg

          I just ran across the patent for the proportional spacing mechanism: https://patentimages.storage.googleapis.com/77/71/30/439f5254172d9d/US2224766.pdf …
