Okay, so I have a pretty basic Tandy 1000 with a memory expansion card so it has 640k, a 5.25 inch drive, and a 3.5 inch drive that I believe is 720k. I would like to put in a hard drive and install MS-DOS 3 on it, but I'm not sure what I need to do. Plus, is there a way I can copy files from a modern PC onto a 3.5 inch disk and use them in the 1000?

One final question: Would this work and allow me to use the multitude of Gameport joysticks on the 1000?:
