Hey guys, this is my first time entering this part of the forum to post something (I love the thread about the tablet!). Anyways, I found an old Powerbook 170 in our barn and i am curious as to what operating system it ran. I am also curious as to how I can get a copy of it. It starts up but it only gets to the point where it is flashing the folder icon, so there must not be anything on the harddrive. Thanks guys. I would love to get this thing going again and put Sim City back on it because I have great memories of playing it the back seat of my dads car, that blew me away at the time.
