Among the things that once confused me in the advertising in Byte and other US magazines was that some companies had telephone “numbers” that contained letters, and I wondered what US telephones might look like. An article in Dr. Dobb’s Journal gave away that there apparently were letters associated with the digits on the dial. Very strange, but eventually, as mobile phones appared, they also had letters on the handset, but they were used for texting, not phone numbers. Until now. This is the first occurrence of alphabetic phone numbers I’ve seen in Sweden, has anyone else seen them earlier?
