"Portland Trailblazers" Roland Jupiter 4

via this auction

SN 902025

"There is an inscription on the back that says "Portland Trailblazers Bill Blunk Oregon." The serial number dates it to one of the last revisions before they switched to the IR3109 Filter Chips, so this one is still BA662. 4 Voices of analog bliss!"

Update via David Anderson in the comments: "A little about Bill Blunk:
http://www.pstos.org/organists/or/blunk.htm"

"Bill has had an exciting and varied career as an organist -- since we have known him, he was organist for several years for the Portland Trailblazer National Basketball team, as well as organist at Uncle Milt's Pipe Organ Pizza Company. Now retired, he still plays regularly at a retirement center, purely for the pleasure of doing so. Needless to say, he is eager to see the Marr & Colton up and playing again, as we all are!"
