If you search ebay or google for a device called an xe1541 or x cable for short you can download disk images and transfer them to the c64 drive, you will need some knowlege of dos and an os that supports it ie win 95/98/me, definitely not xp or nt the software to do it is called star commander and is freely available on the net. A site called gb64.com has around 16000 game images for downloading the hardest part is getting the double density floppies as they are getting hrder to find the 64 is very well supported with software , Wish i could say that about the 128 which i own there wasnt ever much software written for it apart from a few text adventures.
