Re: Yamaha SY99 Disk Drive Belt And Battery Holder

2013-03-28 by alesisfusion8hd

No experience with SY99, but put battery holders on my DX7 and several modules of my TX816. Bought holders for 50 cents each, works well. Spacing is slightly different, but pins on the holder are long enough to be bent. 
Take extra care of polarity.

To save memory during replacement, you may put another cr2032 in parallel.
