Rhodes Chroma Polaris

I fixed my connecting ribbon-- its not easy and you will need a multi-
meter (to see if the ribbon is connecting.

I had cracks going perpendicular to the traces on mine.  I ended up 
cutting the ribbon back to a location before the cracks using a sharp 
scissors.   If it turns out that you need to go so far back that you 
loose the contact area, you need to make a new one.  I used a tweezer 
or dull exacto knife to scratch away part of the black coating on the 
traces so that they would make contact.

Then you plug in the cable, and use the multi-meter to verify 
connectivity across the connector.

Note that some of the traces don't go anywhere (esp. on the right 
side) so you do need to file those.

Good luck, and please keep let me know if anyone figures out a 
solution to the patch tape transfer-- I can't get the mp3s to load on 
my polaris.   I suppose I'll have to do a cassette dump into my 
computer, figure out the levels and match those w/my computer, but I 
haven't had time.
