Best thing to do is to try and get an image off of the AudreyHacking.com files, and get it to a CompactFlash card. There are numerous ways to do it, and they depend on what version of Windows you're running.
NoCharge.com will indeed work on Audrey, but they've been shutting numbers down, the Shelton ones went down a couple of weeks ago, and I was having trouble with the Olympia ones just today. I guess their business model just petered out.
The vi editor is indeed within Audrey, and it works well. For vi, that is!!! There is a text editor, called Pedit out there, its way easier to write or edit files in, then you can save them to locations on your Audrey.
