Anybody remember the Telex machine at Bulwark Rd? I guess it could be likened to an early fax or modem. A monstrosity of a thing, but quite fascinating to my young eyes. It kinda coded in a reverse Braille type of way. Braille was raised dots, this was holes, or the omission of dots, but the same principle. I remember some clever bugger doing a portrait of the ‘Mona Lisa’ in telex. There was a handbook in the operators draw that gave an alphabet of telex letters, and for a short time, I could read the transmissions from the ticker tape that was transmitted/received to and from the telex rather than the analogue printed and typed facsimile. It was a bit like glorified Morse Code or FSK. Still remember it clattering into life periodically. Another useless skill that I acquired along the way
