The Mitsubishi ML-TS1 is a very rare MSX1 computer. It's the small brother of the MSX2 ML-TS2H telephone-computer, and was available in white instead of black for his big brother. The MSX logo does not appear on the machine.

This Telecom station includes a MSX1 firmware and was aimed at the Japanese market. This hidden MSX does not seem to have been distributed, but it was possible to buy it under another trademark: see Misawa-Van CX-5.

This MSX received the Good Design award in 1987.
