"Beautiful example of a Korg DW-8000 hybrid polyphonic synth. This unit is in excellent condition inside and out! All buttons, keys, and sliders function exactly as they should. This board was fully serviced a month ago at Electronic Innovations in Detroit, the very best synth service in the area. The internal battery was replaced and a removable battery holder was installed for easy replacement in the future. Full factory preset patches were installed too. Also included in the sale is the original shipping box and power cord."

E.M.I Ritm-2, analog soviet pizzazz
video by Valmont
"Facts I translated from an obscure russian forum:
- Development started in 1983
- Were made by hand from 1985 to 1992 in the Soviet Union
- 6767 units were built, estimated about 200 to 500 still working tho.
- The factory employed 15 workers: not enough people for a quality build. PCBs were cut and drilled by piles together by hand, the keyboard in an unspeakable handiwork thing...
- SN number starts at 2248 and ends at 9015, so mine is number 91!
- Black models are from the 80's, yellow/white plate ones are usually from the 90s
- Moog-type Ladder Filter (Micromoog or Prodigy?), Moog-inspired envelopes as well
Was just serviced"
