Seiko DS-250/DS-310 Vintage Digital Synthesizer SN 25000189 & 31004072

via this auction

"Rare Seiko DS-250 keyboard with the DS-310 digital synthesizer add-on. This addition makes the DS-250 a programmable additive synth. The keyboard and the DS-310 are in good condition. Everything functions as designed.
Here is a list of everything that comes with the Seiko:

-The DS-250 itself
-DS-310 Digital Synthesizer (programmer for DS-250)
-Power Supply
-Soft padded carrying case for the DS-250

This is the bigger, MIDI capable brother of the sekio DS-202. The DS-320 addon, a sequencer, does NOT work with the DS-250. It is not needed because the DS-250 has MIDI, and the DS-202 does not. There was desktop sequencer made to work with the DS-250 called the DS-1000, but it is useless in this day and age! Please see the photos also."
