If you want to get back into the C64 then pick up a Turbo Chameleon64 cartridge. You can still use your C64 as normal, but if you insert this cartridge it will take over the C64, give you a VGA video out port, a virtual floppy drive to use D64 images, access to T64 tape files, the ability to load cartridge files (Simons BASIC, etc), and lots, lots more.
Unfortunately it seems to be out of stock at the moment.
