	<h1>Model Generated Test Data<br>for the HP-35 Calculator</h1>
	<p>
	A model of the HP-35 calculator has been implemented in perl and  
	used to generate the self consistent randomized test data which
	is reported below. You can save this particular data using your
	browser's <i>Save As</i> menu. You can also try one of the following.
	</p>
	<ul>
	<li> Generate <a href=hp35.cgi>more</a> test data.
	<li> Use data like this to <a href=run.cgi>run</a> the test.
	<li> Read the <a href=hp35.txt>source</a> of the generator.
