Whoa! ZX Spectrum Rendering! 
hock: It will always run slow 
.
Are you using Floats or Fixeds? Also, the RND is already optimized and produces a better random pattern than the ZX Spectrum one. You should perhaps try a random Stream generator? (I've used in cryptography: <!-- m --><a class="postlink" href="http://en.wikipedia.org/wiki/Stream_cipher">http://en.wikipedia.org/wiki/Stream_cipher</a><!-- m --> random bit generator?)
