“I have always wanted a TRI-Function reCORDER.”
Pah! I want an OMNICORDER.
Anyway, back in the day I managed to get hold on an early Phillips cassete tape recorder. The one originally intended for office use as a dictaphone with the one-knob-control. Came in a faux leather case with a shoulder strap. Close enough for kiddies doing a bit of Star Trek LARPing in a mid-1970ies backyard. Not that anyone used the term LARP then. We were just kids playing and having fun.
