Made in PA, this was one of the earliest digital wave 8-channel synthesizer and sequencer within reach of most working musicians.    This is a well maintained unit, and has been used in the studio for the last 25 or so years.  When I purchased it, had the sequencer expanded to it's maximum size.  I also have a copy of the original manual, an external EPROMs cassette that expands storage from 40 sounds to 120 sounds.  I also have 2 cassettes containing 9 volumes of additional sounds that can be loaded into the ESQ.  Of course there's a power cable included, and a diskette the contains I believe programs 1-40, which is stored in the ROM.
