This particular SN has come up a few times over the years. I heard Roland re-used SN numbers.
"Works fine - sequencer, finger keyboard, output, battery power, headphone output, and all sliders and knobs seem to work perfectly. No discernible pot or slider noise. I have not checked the CV functionality or tape backup, but have no reason to doubt they are working, as everything else works fine and unit has only been used lightly since purchase."
