I first saw a model 35 as a computer terminal in Holland, not sure what computer (it showed up in an Open House demonstration). But yes, model 33 was far more common. Presumably because of being far cheaper, and "good enough". They were rated for intermittent duty, and sure enough, when used intensely in college timesharing setups they tended to fall apart.

The LA36 was an excellent machine. Unlike the LA30, with its atrocious keyboard and a print mechanism that jammed about every 20th carriage return.

I remember my father used them in his lab, to capture experimental data for subsequent processing. Nice machines. The most amazing catch would be a Soroban punch, those apparently could go at 200 or 400 bytes per second (vs. BRPE at around 120 or so).
