[GreenKeys] Teletype Model 33 ASR vs. ASR33

[Christian Gauger-Cosgrove]

You can see the term in use in documentation from 1963.

Did the message I sent with the link to the DEC brochure for the PDP-4
go through? Because they called a 28KSR a KSR-28. (If the link didn't
get through... BitSavers --> PDF --> DEC --> PDP-4 --> "F-41D PDP-4
Brochure September 1963"; page 5 of the PDF under the "Printers"
heading it refers to the Type 65 Printer-Keyboard and Control.)
