The Yamaha PSS-110. Not the first PortaSound, as it was introduced in 1984 (the PS-1 in 1980), but an early model with an endearing look, and in the first wave of PSS models. Very simple miniature key music keyboard, with unusual chorus effect and arpeggiator [edit: wrong, no arp, no chorus]. Depeche Mode used one.

Anybody played this model? Or another PortaSound maybe?
