My one and only exerience with a '33 was at (the then) Lanchester Polytechnic, where one was made available to our school. I was astounded that it shook so much! Amazing to think it is all electromechanical.
My current interest is their frequent use with the earliest microprocessor systems ( visual displays came later). I suspect it is no coincidence that BASIC lists in the same format as a program is entered. This was exploited to save programs by turning on the punch before completing a 'LIST' command.
I missed all that, of course. And I missed the analogue era
