Part of an estate sale . I believe the synths that this worked for were sold off before I got involved with the lot. I would guess it works but I cannot test nor am I sure exactly what synths its for- dint find a lot of definitive info.

unknown what this is for, search of reverb suggests it works for the followng but i cannot guarantee that , or if it works.

possibly For Roland A-50/70/80/90; D-5/10/20/50/70/110/550; JD-800/990; JV-80/90/880/1000/1080/2080; U-20/110/220; R-8/70; TD-10; VG-8.
