This article intrigued me this week. In the cold war years the eastern block states had extensive files with the details of all typewriters [you had to have a license to own one] with their individual characteristics; eg slightly low ‘e’.
There is something really beautiful about the look and feel of antique typewriter keys. The physicality of manual keying is a balm to today’s disconnected technological way of living. Not that the two need be separated. Probably why some steampunk enthusiasts turn their regular computer keyboards into hybrids? Interestingly, apparently certain Russian agencies are reverting to typewriters to prevent wikileaks style security breaches?
