Re: Ah, the "good old days" ...
Yup - worked on one of those, waaayyy back.
And a 'decollator', too
An upright triangular device... shelf across the bottom where the stack of multi-part stationery sat... drag the paper up to the top of the triangle by hand and separate, one paper 'part' over a rough-coated roller, wind the carbon paper round a spindle, and the remaining 'parts' across a rough roller on the other side.... switch it on, and the rough rollers would provide enough friction to drag the paper through and the spindle would rotate to take up the carbon paper.
The trick was to adjust the speed of the thing to a maximum that allowed the job to be done without spewing finely creased paper across the room at a high rate of knots.
