I've had this thing since it came out in 85'. The internal battery 
was dead in the water and there was no back up of any knid so I had a 
datadump. It was the first synth my late father bought me when I was 
15 tired of playing saxophone. Does anyone know of a site or would be 
a kind soul to share with me some data sheets to get some various 
sounds loaded. Brass, Bass, Pads, Sweeps, Organ etc.

The thing is kinda limiting while I have been gradually building 
sounds again.

Any help would be appreciated
