Eml synthesizers

Hey all, 
I recently picked up at second EML 101 SN 246. This one has +5 Volts, Glide, Gate, CM2, and 
CM3 in the Keyboard section. My other 101 is SN 1204. It has +5 Volts, Glide, Gate, CM2, 
and Seq in. Other then the Keyboard section they appear the same. 

I've been trying for a while now to patch them together so that 1 keyboard controls the 
oscillators on both synths but I can't figure it out. If anyone out there could shed some light 
on this it would be greatly appreciated. 

thanks
