Mac SE FDHD Start up
I have an old MacSE from 1990 and wanted to startup after maybe 20 years. It starts up but it shows a disk with a blinking Question mark. Do I need to insert a disc to see what I put on the hard drive? I would like to give this computer to a local computer museum but want to delete any documents, personal info, etc before donating. I was unable to locate any old disks I may have had. Any input would be helpful. Thank you.
