Yamaha GS-2 help

[|||| Philip Pilgrim ||||]

Hi,

I just revived a Yamaha GS-2 (Grandfather of DX-7, Father of DX-1,
Ancestor of sampler and bastard son of Mellotron)  :)

Anyway I didn't have time to remove the Faraday Shield over the main
board but I'm curious if a battery is there. The unit loses patch memory
after 5 min. It's age is late 70's? SO I guess it's battery would be
choking about now.

Anyone with experience with these?

Philip

btw The GS-2 is an Analogue FM synth that reads magnetic strips
programmed at a yamaha lab. The strips contain information that
configures the FM ops inside. 

The interesting thing is that it is like a very slow sampler. First you
record a sound on 1/2" 2 track tape at 15ips (guess). Send it to a
Yamaha lab. They FFT analyse it and generate a card strip with the OP
configuration thend send it back.
