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. The power supply is external.

This computer was intended for companies, it was not distributed in shops, but it was possible to buy it under another trademark: see Misawa-Van CX-5.

This MSX received the Good Design award in 1987.
