Well it does what it says on the tin. So its fine. Whats your next step? Perhaps put a version of snake in there. That will provoke input/output etc... I'd suggest text mode first but then aim for VGA and beyond. If you want a bigger challenge, implement serial port I/O so you could hook it via virtualbox etc to another running machine and network your snake game etc. Then from there dig into ethernet and use raw ethernet or even UDP. Now you have a full working network client from the ground up.
