 <P>Tom couldn&#146;t spare the gates or the time to do a full FIFO, but he could implement a one-deep FIFO, allowing the CPU to get one write ahead of the VGA. He wasn&#146;t sure how well it would work, but it was all he could do, so he put it in and taped out the chip.</P>
 <P>The one-deep FIFO turned out to work astonishingly well; for a time, Video Seven&#146;s VGAs were the fastest around, a testament to Tom&#146;s ingenuity and creativity under pressure. However, the truly remarkable part of this story is that Paradise&#146;s FIFO design turned out to bear not the slightest resemblance to Tom&#146;s, and <I>didn&#146;t work as well.</I> Paradise had stuck a <I>read</I> FIFO between display memory and the video output stage of the VGA, allowing the video output to read ahead, so that when the CPU wanted to access display memory, pixels could come from the FIFO while the CPU was serviced immediately. That did indeed help performance&#151;but not as much as Tom&#146;s write FIFO.</P>

 <P>The problem, of course, is how to go about transcending limits you don&#146;t even know you&#146;ve imposed. There&#146;s no formula for success, but two principles can stand you in good stead: simplify and keep on trying new things.
