I am trying to open my Mac Powerbook 190 which I bought in the 80’s. Unfortunately, I have forgotten the password. Is there any way I can get over this problem. Thanks for any assistance

Original Mac OS: 7.5.2 Supported Mac OS: 7.5.2-8.1 Boot up from you original system installation disk or retail 7.5.2 to 8.1. Insert the disk and start up holding down the “C” key. Go to the second page (if I remember correctly), then to the pull down menu to the change password option. http://www.everymac.com/systems/apple/po
