<h1>Introduction</h1>
<p>µHz (Microhertz) is a graphics demo for the TI-83 (+) series graphical calculator. It doesn't cheat and run at the SE's 15MHz, (hence the title), so will run just fine on the regular 83+/83.</p>
<p>It was written by Ben Ryves for <a href="http://www.maxcoderz.org">MaxCoderz</a>. In retrospect, <i>Pixel Madness</i> wasn't as mad as it made out to be, and the unfinished competition 'sequel' was ugly, slow, and... well, a bit rubbish. Hence this!</p>
<h1>Installation</h1>
<p>There are two binaries; one for TI-83 Ion, one for TI-83 Plus MirageOS. I'm assuming you know which calculator you own and shell you use! Just send the relevant *.8xp/*.83p file to your calculator using your file transfer program (TI-Connect, GraphLink, TILP, FastLink, ...), run your shell and open it from there.</p>
<h1>Usage</h1>
<p>Just let it run! You can skip through scenes with <span id="key">Clear</span> if need be. As the frame rate is not blazingly high in some scenes, make sure to hold the key down for a bit before releasing it.</p>
<p>If the display is not clear enough, you can press <span id="key" class="blue">+</span> or <span id="key" class="blue">-</span> to adjust the contrast. Pressing <span id="key" class="blue">Enter</span> at any point stops the current scene from automatically advancing after a delay - only really of use if you feel you really need to keep on watching one particular scene!</p>
<p>Some of the scenes have 'hidden' keystrokes. Have a play with the cursor keys!</p>
<h1>Thanks</h1>
<p>Many thanks to Mike G for providing the BBC Micro font. The photos used for some of the graphics are from an old Corel stock CD. The TI-83 Plus developer guide was very useful (display driver reference), for a change.</p>
<h1>Source Code</h1>
<p>Unsurprisingly, this was written in Z80 assembly language. More surprisingly, it was written to be assembled in Brass, not TASM. Visit the <a href="http://benryves.com/bin/brass">Brass</a> website to download the assembler. Even better, download <a href="http://benryves.com/bin/latenite">Latenite</a> (in development at the time of writing) and you'll be able to open the Latenite project file and build/run the source/binary with a single keystroke.</p>
<p>You can find the source code in the '/Source' subdirectory of this zip archive.</p>
