Hi - new here. I found my old Powerbook Duo 230. I got rid of the monitor and Dock years ago. The Powerbook surprisingly still works perfectly, but I have no use for it. I don't need any of the word files that are on it and I manually deleted them (moved to trash, emptied trash). I only have the manual and not the original software (and no external drive) but I have no reason to use or keep the Powerbook anymore. If I decide to sell it, I assume I'd first have to buy an external hard drive and the OS floppy to reinitialize the hard drive (for safety/security reasons)? There is software (word, games, etc.) installed already, but I want to make sure the files I deleted can't be recovered. I'm hoping to do this without a lot of expense and I'm looking for a simple technical solution, if possible. TIA for your help.
