Yamaha PSR-36
The PSR-36 from 1988 is unique in that it uses a 2 operator FM chip, the YM3420, which is a close relative to the YM3812 and YM2203 used in AdLib and SoundBlaster cards from the late 80s and early 90s used for PC gaming as well as many arcade cabinets that were published between 1985 and 1988. It is not 4 operator like the TX81Z, FB01 or Sega Genesis/MegaDrive, but slightly more primitive sounding. It has 32 patches, all of which can be modified with 6 sliders: Spectrum (various 2 operator algorithms and modulation amounts), Brilliance (harmonics), Envelope (assigned to modulate the operators against each other over time), Vibrato, Detune (similar to a unison mode) Sustain selector (3 sustain/release envelopes). These controls give it just enough variation while still sounding like simple yet classical FM voices. It can really sing by adding reverb, delay or chorus. IT also has the other feature s that Yamaha PSRs keyboards are known for such as PCM rhythms and auto accompaniment. It has a midi input, a single multitimbral part, and 9 voices. Watch a demo here.
