UDMA CF cards work in Epson P-3000 photo viewer

The Epson P-3000 photo viewer is a nice piece of equipment for a photographer to have, allowing you to back up 120 GB of photographic data [1] and view photos on a 4" screen with histogram and shooting data. But it's very old. So, it's surprisingly nice that it still works with the most advanced compact flash cards. I successfully backed up Lexar 1000x UDMA 7 16 GB compact flash cards to the Epson P-3000.
