I think that the Polaris may have used a similar numbering convention as the
Rhodes Chroma. Specifically, the first three digits (212) designated that
it was a Polaris, and the third number signified the 'market' that the unit
was produced for (North American, European, Japanese, Australian). {Check
out a discussion on the Rhodes Chroma mailing list, as below:
