Circuit Overview:
     The MKS-80 is often confused as a 'rack version of the JUPITER 8'. Rather the 80.1 version uses JP-6 chips and also Software generated EG's but apparently more rigorous ones since everyone raves about how much faster they respond than the JX series. They have a more 'natural' character I'd say.

Service Tips:
      I've only done board damage repair on these. Not aware of particular reliability issues.

Roland might still have some parts for these so always check there first. Let me know if you need a specific part from my listings in the parts section that you don't find elsewhere or whatever.
