Amy is by Thorsten Greiner.  It's a Winboard program, but I think it was
originally a Linux program, here is his website
http://www.geocities.com/hiiamamy/

I had forgotten about his website when I downloaded it yesterday, so instead of
going directly there, I got the program at Dann's ftp (Amy directory)
ftp://38.168.214.233/pub and for the opening book, I used one that Frank
Quisinsky has for download at
http://amateurschach.in-trier.de/schach/engines/english/amy.htm

Amy's relatively strong, and kind of fun to play games against as I recall.
