Very interesting, David.? I have a model 15 which
I acquired around 1968 and used for many years here prior to the
ubiquity of PC's.? The machine in the video described as a model
14 is not.? The model 14 was a typing reperforator usually with a
rotary TD attached to transmit.. Because the paper tape was also
used to transmit it needed holes, but if you had holes you could
not read the print.? The solution was to punch "toilet lids."? The
chad was attached to the paper tape by being punched almost all
the way around.? I had one and let it go many years ago.
I will be happy to share any and all, as well a few stories about
using the model 15 and it's quirks.

For all you RTTY / Teletype fans out there, this is a fantastic
video taking the viewer through how a teletype unity actual works
including details into Baudot 45, a full teardown and rebuild of
both a typewriter style and ticker-tape style teletype, etc.?
Great stuff and well worth your time:

This video comes from "Usagi Electric" who has made a lot of other
great videos on building his own vacuum tube based 1bit computer,
restoring various tube and legacy Mini computers, etc.?
