Model 35 machines are similar if I recall, though they do have
significantly different mechanics, and support a lot more features
than the 33 (being part of the 28 line they had access to a lot of the
28 features, like vertical tabulation).
Also reliability. Even though model 33s were often used heavily, they were rated for
?intermittent service? (4 hours per day). Conversely, the 28 and 35 (and 15, I suspect)
were rated for continuous service.
Our timesharing system model 33s tended to fail a lot because they were pushed beyond
their design service limits.
