[Kenwood] TS-950SDX EPROM discontinued

Wed Sep 9 14:59:15 EDT 2009

If you want to pull hair on the TS950SDX go to www.kenwoodparts.com and go 
to parts search and put in 27c512. I think I count 6 different versions of 
the 950SDX software. Several of the 870. The SD has several under 27c256 as 
does the 850.....

More than just 1 or 2 versions out there.
