Vintage 1985 Korg DDM-110 Super Drums. Just serviced, all electrolytic capacitors replaced, all pots/jacks/switches cleaned/lubed, all solder joints reflowed. Tested - all sounds work, was able to create save and replay a drum pattern. Everything seems to be working except I haven't checked the 5 pin din (not midi) sync jack or the tape recorder save/recall jacks because I don't have the facilities to test them. Takes 6 AA batteries or 9vdc adapter (neither included), battery compartment is clean with no corrosion. Has some marks and scratches but all the text/labels are there, overall it looks pretty good for 40 years old. Manual available online with a simple google search. No returns, warranties or guarantees.
