Not quite what you are asking, Dennis Ritchie provided a list of
terminals he used at home.

"for the sake of history, here is the sequence of terminals I have used
at home, all paid for by my employer. Dates are approximate.

1968: IBM 1050 (14.5 cps)
1970: Teletype 37 (15 cps)
1975: GE Terminet 300 (30 cps)
1978: HP 2621 (120 cps)
1983: Jerq (Blit) (120, later 960 cps)
1990: Gnot (Plan 9) (960 cps)
1992: Gnot (Plan 9) (8192 cps ISDN)"

When John Lions was at Bell Labs on sabbatical:

"Up till now I have been using a tty 43 (this listing)
...
there is a noticeable preponderance of hard copy and lack of CRT terminals."

"Unix in 1969 was mostly written on a TTY33. Our PDP-7 also had a
full-ASCII keyboard that was part of the locally-built Graphics-II
processor attached to the PDP-7, used for Space Travel, for example,
and also for development once Unix was self-supporting."

Dennis mentions an ASR33 for the initial PDP-11 in:
