Yamaha PortaSound MK-100.

A unique, non-FM '80s keyboard from Yamaha. The timbres are preset synthetic keyboard sounds, but the one of a kind Multi-Menu allows customization of envelopes, layering, percussion, and a couple of other elements.

While I avoid throwing around the word "rare", these are a little hard to find, and this little gem is absolutely pristine; it's truly difficult to tell it from new condition. It comes in its original box, with original documents and an OEM multi-plug 9v AC adapter from the same era.
