i agree that someone can\'t type. there are only two references to 960, so it could be one typo. every other instance of mentioning model numbers lists them in ascending order, except this one: i guess it\'s meant to say 860, 870, rather than 960, 870. Since 870 is referenced repeatedly, and in the name of an ipk (much less likely to be misspelled), I believe that one. However, I still don\'t know what its features are.
