Roland CR-1000 (1986)
Digital Drummer

 

A kind of preset version of classic drum machine TR-505 with same samples soundset but inexplicably lacking the great sequencer.

Part of the famous CR - computer rhythm - series started with the famous analog CR78.

3V Cr2032 soldered to mainboard although there's is not much data to save since it is a preset machine... maybe Midi channel setting? Probably you won't even notice battery is dead.
