Thanks to all that responded already. Sorry I had to turn some of you down - G727s seem to be hot items. Anyway, I have a pair of hardcover books from Apple - ProDOS 8 Technical Reference Manual (1982, 83, and 87 dates, Addison Wesley), and BASIC Programming with ProDOS (same dates, same publisher). Pretty good condition - with the dust sleeves. Anyway, anyone want this pair for $3.00 plus shipping? William Donzelli aw288(a)osfn.org
