Here is a Roland CompuRhythm CR-8000 drum machine.
This is being sold as spares or repair.
The button for the start/stop is missing but the switch still works. A lot of the switches need a “wiggle” or extra pressure to get them to function. The 1st bank selector switch is not working, although that bank can still be accessed as it goes to the 1st bank on power up by default. All the voice level knobs are working. I don’t know if any of the programming side of it works, as i don’t know how to operate it! Some of the leds do not light up.
