Found in a no-longer-used British Rail communications room at a village railway station, a group of endless loop tape cartridges. It's time for Britain's most interesting tech boffin, "Techmoan" to figure out what's on these old tapes. First, what company made these tapes? Second, is there any message on these tapes? Third, can these tapes be played on a "modern" reel-to-reel player/recorder? It's "lemon-squeezing time" with Mat; who knows what BR was doing then...
