Circuit Overview:
These machines are one of the first really well done interactive workstation environments with styles and so forth so I threw them on here. I2 is 76 key version and I1 88 weighted keys. I-4S and I-5S followed with some new tricks and built in speakers. Or maybe not the 5S. Not sure about that on the speakers :-)
Service Tips:
Not sure, probably common cleaning issues now. I think I have keys for these..
