Oh, yes, I remember the 3/4" tapes on both the Burroughs 220 and the Honeywell 800. The 220 tapes had two "lanes" of data, that is, were logically organized like two tapes side by side. The 800 tape drives had vacuum hub clamps, and occasionally you couldn't get one of the damn things to let go of the reel. This was more serious than it sounds, for in batch processing every idle second was money down the drain. The most picturesque of the 3/4" handlers that I encountered were the Burroughs Datafiles, a.k.a. the "Datafail." These were 3/4" tape loops in large bins (they looked like mummy cases lined against the wall) without vacuum tensioners; the tape would pick up a static charge and wrap around the capstan with dire results ...
