Vintage Baldwin Discoverer DS-50 SN BC2801788
via this auction
"It came out in mid/late 70s (pre-MIDI) and features some control over the synth sounds plus a built in drum machine. It is missing one of the knobs. The auto-accompany can be turned on or off and split at the keyboard (rhythm vs melody). There's a built in speaker but it can be bypassed using the audio outs. This makes it easy to implement in your home studio. They really built instruments to last in the 70s. The DS-50 is made of metal and really well constructed. Original power cord is included."
You can find a demo of one posted here.
