HP isn't showing much info, or drivers... Files I saw briefly showing being dated 2003.... Maybe that's why you can't find any reviews on it?
BTW: 1.3, 256 ram.... How old is this machine? Price?
With the specials they are running these days on NEW machines it would have to be at next to nothing to be worth fooling with.
You better price a battery on that machine, and the cost to bump up the ram.... Then add to that you have no warranty more than likely?.... and it's going to be hard to get service on? and due to the age components within the unit are not long for this world....
(Yes I know it's sometimes "fun" to revive something "old"...just some thoughts.... on why you might pass on this "deal".)
Buy it if you want, but you can buy a new machine for pretty cheap.... all new... plenty of current owners out there... currently supported product, etc.
PS: On trying to find a review. You may be able to find something searching with : Pavilion ZT1000 series, ZT1145, ZT1170, ZT1210, ZT1235, ZT1250
