Summary[edit]
Three French trucks toured Europe several 1970s years demonstrating the IBM 3750 Switching System.
The 3750 was the world's first stored-program-controlled PABX (Private automatic branch exchange): it was developed in the early 1970s in IBM's La Gaude laboratory close to Nice in southern France.
This photo was taken in London -- many 3750 and later 1750 systems were bought in the UK and other European countriesDuncanogi (talk) 19:31, 30 April 2019 (UTC).
