Old Casio keyboard (HP12 Nr Booker Airfield)

Please note that this keyboard is very old, sounds old compared to the Yamaha pss AWM series back in the 90s and would only suit a child who would only want to randomly press keys. May also be suitable for a retro keyboard collector.
Batteries already in device and still working but no box or adapter.
