It'll run great on that machine. It works for me on a computer with a 1.2 Ghz proc, 128 MB of RAM and no hard drive. A disavantage is that saving things is a pain. For example, if you get a high score in a game and you restart, you lose that. If you want to save a document, you must save it to a USB drive, CD-RW or hard drive (but not NTFS). You can use configsave to save your settings. With your RAM, you can copy it to RAM and it'll run like lightning. Have fun!
