It's been roughly 20 years since I have done anything with a Commodore 64.  It was just sitting in the closet after an online friend traded for some software that I had for a system, which included a 5 1/4 inch disk drive, known as the 1541 disk drive.

Along with the Commodore 64 with an ATEC monitor which provides a good screen quality, it has a uIEC/SD device from Retro Innovations with a 2GB SD card, and a Link232 RS-232 device from Daniel Mackey, which you can purchase on eBay.

IT IS NOW ONLINE! Telnet to port 6400.

Use a program like CGTerm or SyncTerm.
