Korg DW8000, Mono/Poly, MS-20...

Hi there.. first off I'm a member of this board for a lil while but 
decided to post something just now. I recently got a Siel DK-80 Synth 
from a pawn shop for ten bucks (!) It seems to be in good shape but 
lacks the power supply that fits to it's weird power connector. 
Anyhoo.. the siel looks very much like a poly-800/dw-8000 and wonder 
if siel had kind of a partnership where roland shared their design 
with siel? Oh, and could anyone here spare a DK-80 power supply? I 
desperately need one to see if this synth works at all, but it seems 
like the power supply is much harder to get than the synth itself?
