it is a 14 pin, CMOS sized IC. i cant find anything in the search history here, and on google, i just come up with a post from one guy who is looking for the same chip.

Only 12 years to late! While tearing apart a trashed Lowery home organ I ran across the bunch of these 25539 chips. Maybe I'll post them for free in this forum.
