During our PDP-12 debugging today we found that the left tape head has an
open coil for data track 0. The left head was OK a little more than a year
ago when we found the open coil in the right head. One TU56 head on my
personal PDP-8/e also had an open coil when I got it.
DECtapes record everything twice (5 logical tracks, 10 physical tracks). Are there 10
coils or only 5? If 10, does the redundancy work well enough?
