I have a falcon purchased new when released It has been stored for 10 years. Iam trying to get it going but takes 2min to start and end up with a blocky basic desktop. only trash,menues and mouse pointer no drives. I think rom screen.Original disks seem not reading. I have just down loaded system discs to try. Question is. if my battery is dead would this be the symptoms or what are the symptoms. or what could my problem be.
