Casio SA-46A An Excellent little keyboard in great condition, it comes packed with features I could only dream of when I got my first keyboard age 6 (that was the Yamaha PSS80… I still have it!) 100 tones, arranged in similar format to General MIDI 50 drum patterns to play along to 10 songs with melody remove feature to allow you to listen and learn then play along while the keyboard chooses the tones for you. Plus drum pads and more! It takes a 9.5V casio power adaptor or 6AA batteries. I recommend Lidl’s Tronic rechargeable batteries, they cost about the same as the adaptor but allow for almost constant portable use!
