I recently posted an account of the installation of a 7 track head to a 9 track tape drive, allowing the magnetic flux reversals to be recorded by a logic analyzer and converted to tape contents by software postprocessing. Because I took no pictures during the work, the prior entry was pure text. A reader has asked for pictures (for the work in question and also for future posts).
