Rhodes Chroma Polaris

New on the Rhodes Chroma site this month is the entire Polaris Service  
Manual in hypertext format, including large format schematics in PDF.

The Computer Tutorial may be useful as an introduction to the state of  
the art in the mid-1980s. Circuit Descriptions provides an overview of  
the main board, control panels, power supply, and output board.  
Disassembly covers just that; Diagnostics and Adjustments and Checkout  
should be useful for those who are repairing a Polaris keyboard.  
Options deals with memory and EPROM upgrades; and the Parts List  
"outlines most parts needed to service the Polaris."

Thanks to Steve Grom [21030502] for supplying a copy of the manual.

Thank you very much Steve Grom.  That is going to be very useful in my getting my Chroma Polaris up and running.  It sat for a while and it lost it sounds.  I was wondering,how do I access that information.
Thanks again
