1985

June - the SECAM coder was introduced. It was a small, simple unit designed for upgrading the famous SINCLAIR ZX SPECTRUM and SPECTRUM+ personal computers. Because of an tremendous success of VHS system, Elbox designed and started to deliver PAL decoders for SECAM-system CTV-sets. By the end of the year we designed more than eight models.
