Seiko DS-250 + DS-310 Programmer

I recently picked up the rare DS-310 programmer to go along with my DS-250 and it’s really turns the synthesizer into a beast. There isn’t much information about it online and I know an owners manual exists for the 310 but its just as hard to find as the programmer itself!!!

If anyone has an owners manual they wanna scan, myself and the rest of the small seiko synth community would greatly appreciate it :slight_smile:
