Primitive trackballs actually predate mice. I used a home-made one in the Cambridge Computer Lab in 1971. I also used commercial ones on Vector General graphics stations in the mid-70's. AFAIK the first mouse was born when someone (Douglas Englebart?) turned a trackball upside down. poc -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
