A cute tape retensioning story: On the old ICON boxes, the tape drive that was used was placed right on top of some moderately hot hardware. Tape, being thermoexpansive (ie: it gets bigger when you heat it) would act unreliably on these boxes. The workaround was to "retension" the tape. In reality, this really dis nothing useful except run the tape back and forth (or forth and back, actually) and heat it up to a uniform temperature because of friction at the capstan for the drive roller. In my experience, retensioning is a pretty darn useless waste of 5 minutes per tape load.
