Vintage Synth Repair

On the subject of Ensoniq,  is there any sort of service data out there on any 
of them?  We serviced them way back when,  bu tin those days they were so 
proprietary about them that they didn't want to part with _any_ info on the 
innards of them at all,  swapping whole subassemblies instead.  I've seen 
mention here and there of some sort of data out there,  and would be 
interested in seeing it if so...
