No name, no logo. had 2 separate thrift store stickers. Got it for $6.
Built-in demo using its own instruments. Did a reverse image search and found out it was called the Hing Hon EK-001. A square wave keyboard released in 1988(?) with 2 voice polyphony. It was once a popular toy to mod. Unfortunately for this one, the master volume is inconsistent, and the headphone jack hard clips any audio.
