Transfer Files to Powerbook 520c
I have a Powerbook 520c, ethernet adapter, serial adapter, floppy disks, and a plethera of old PCs run linux and windows. I have been trying to transfer files to the powerbook by file sharing, ftp, and even by floppy disk. The OS on the powerbook is OS 7.5.5, and it uses Mac TCP for ethernet networking. While I am able to setup networking, I have no idea if it actually works or not when connected. I have heard of transfering files using a serial cable, but I am not sure if this a viable option due to the OS. My question is, how can I transfer files to and from the Mac reliably, and if I can, how do I upgrade the OS to the latest the powerbook supports, which is 8.1.
Mac OS 8.6 or Earlier, Mac has 12mb of Ram
