Made in the 1980's in Japan for Realistic - The 49 Key Concert Mate 700 works great. Tested with batteries only as the AC/DC supply pack is missing.
All types of features for drumming, tempos, themes, sounds, volumes, recording etc. All appear to work A-OK.
Missing the back battery compartment cover, so there is a classical piece of Duct tape over the opening ! Takes 6 AA (1.5V) batteries.
All keys in place, but some discoloration from age on the white keys. No chips or cracks found.
Measures: 26 inches long, 8 inches front to back and 2 1/4 inches deep.
Fun for the kids (try them on this one before you spend big bucks on a full size unit!) or have a little fun yourself and learn some tunes for Christmas!
