[GreenKeys] Teletype Model 33 ASR vs. ASR33

[Christian Gauger-Cosgrove]

It most probably started coming from the DEC people. For the earliest
example I can find, the brochure for the PDP-4 (brochure printed in
1963); on page eight of the brochure (page five in the PDF, found
here: <http://bitsavers.org/pdf/dec/pdp4/F-41D_PDP4brochure_Sep63.pdf>)
you will see "PRINTER KEYBOARD AND CONTROL - TYPE 65" as one of the
peripherals, it calls the Model 28KSR a "Teletype Model KSR-28"
(running at 100 WPM).

Fun vintage computing fact: The PDP-4 was the first DEC PDP machine to
use a Teletype Corporation teleprinter as its console terminal. (The
PDP-1 made use of either a Soroban modified IBM Model B, or a Frieden
Flexowriter; though the PDP-1 did have Teletype Corporation equipment
in it, namely the tape punch was a Teletype Corp. BRPE punch.)

Also, as a fun fact, after the PDP-4, every DEC system that had a
Teletype Corporation teleprinter as its console (which was every
system except the 14 and 16 industrial control machines) used a Model
33 (or a 35 for more rugged applications, but usually a model 33).
Though, the PDP-7 did have the option of being setup with a 28. They
also had a lot of flip flopping between calling a teletype the KSR33
or 33KSR. Some documents have both interspersed (oh the joys of not
yet having a standard documentation style).

Cheers,
Christian
