Yamaha DX100

The DX100 is a 4-operator FM synthesizer and is a keyboard version of the TX81Z. It has 8 FM algorithms available and is patch-compatible with the DX21, DX27, and TX81Z. It has pegs for connecting a guitar strap for live play and can be powered with 6 "C" batteries.

In spite of being one of the lower-end keyboards in the DX series it is known as a classic synthesizer due to its heavy use in Detroit techno and was used by Derrick May, Juan Atkins, and Kevin Saunderson.

Thanks to Paul Read for the service manual and schematics.
