 <h2>The Lineup</h2>
 <ul>
 <li><strong>The heirloom machine</strong>, kept as close to factory-original as possible, running the stock TOS 1.04 with a classic floppy drive and its own original Atari keyboard and mouse. Its job is to be a baseline reference: if something breaks on a modded machine, this one proves the fault isn't in the software.</li>
-<li><strong>The "Low" machine</strong>, a bargain-bin Mega ST 4 rebuilt with a <a href="/retro/storm-cloudy/">Cloudy/Storm ST combo</a> for TOS switching and extra FastRAM, a <a href="/retro/gotek/">Gotek floppy emulator</a>, an <a href="/retro/ultrasatan/">UltraSatan</a> hard disk emulator, a <a href="/retro/sidecartridge/">SidecarTridge multi-device</a> for ROM, floppy, and Wi-Fi tricks, and a <a href="/retro/atari-networking-bbs/">Wi-Fi modem</a> for dialing into BBSs. It also uses an original Atari keyboard and mouse. This is the demo- and game-machine, optimized for fast disk-image swapping rather than serious productivity.</li>

 <li><strong>The "High" machine</strong>, the workstation build. A <a href="/retro/monsterboard/">MonSTerBoard</a> adds 8MB of AltRAM, IDE storage, and flashable TOS (currently TOS 2.06), running Geneva for real multitasking. An <a href="/retro/et4000-experiment/">ET4000 graphics card</a> drives a dedicated monitor for higher resolutions. A <a href="/retro/netusb/">NetUSBee</a> adapter and an <a href="/retro/eiffel/">Eiffel interface</a> for a PS/2 keyboard and mouse round it out.</li>
 <li><strong>The spare Mega ST 2</strong>, a reserve and donor machine, kept in largely original condition, used to safely test upgrades before they go into the "real" machines.</li>

 <p>Original Atari keyboards are getting rare and expensive. The Eiffel is a cheap, modern alternative that brings a standard PS/2 keyboard and mouse to the machine, along with the two joystick ports the original keyboard had. It also gives a much better typing feel: I use a Cherry PS/2 keyboard, which is far more pleasant to type on than the original, and a Logitech PS/2 mouse that tracks noticeably better than the original Atari STM1 mouse. It makes the workstation far more practical to use day to day. The older Eiffel versions were originally built and sold by Lyndon Amsdon, with the design documented on the <a href="https://hardware.atari.org/eiffel/index.htm" target="_blank">Atari Hardware Guide</a>, and the project history is covered in the <a href="https://wiki.newtosworld.de/index.php?title=Eiffel_Interface" target="_blank">Atari Wiki</a>.</p>
 
 <h2>My Setup</h2>
-<p>In my Mega ST 4 "High" machine the Eiffel connects the PS/2 keyboard and mouse, keeping the workstation fully usable alongside the <a href="/retro/monsterboard/">MonSTerBoard</a>, <a href="/retro/et4000-experiment/">ET4000</a> and <a href="/retro/netusb/">NetUSBee</a>. The original Atari keyboard and mouse are now used with the "Low" machine.</p>

+<h1>mouSTer: USB Mouse to Atari Adapter</h1>
+<div class="detail-content">
+
+<p>My <a href="/retro/atari-mega-st-fleet/">Mega ST 4 "Low"</a> machine uses a mouSTer, a universal USB HID to DB-9 adapter that lets me connect a modern USB mouse to the Atari. The original Atari mouse isn't in use here, instead the mouSTer gives the machine a far more comfortable USB mouse.</p>
+
+<h2>What the mouSTer is</h2>
+<p>mouSTer is the first fully configurable USB adapter for old computers, created by willyvmm. It plugs into the DB-9 mouse/joystick port of an Atari ST (and many other old computers) and lets you use a modern USB mouse. It's open source, with firmware updates done easily via a USB memory stick.</p>
+
+<h2>What it can do</h2>
+<ul>
+<li><strong>Atari mouse emulation</strong>, so a USB mouse behaves like the original Atari mouse.</li>
+<li><strong>Full configuration</strong>, adjustable mouse speed, full button mapping, and configurable autofire on any button.</li>
+<li><strong>Wide USB support</strong>, it works with essentially all USB mice and gamepads.</li>
+<li><strong>Easy firmware updates</strong> via USB memory.</li>
+</ul>
+
+<h2>My Setup</h2>
+<p>On the Mega ST 4 "Low" machine the mouSTer connects a USB mouse to the DB-9 port, giving a much better feel than the original Atari mouse. It works alongside the <a href="/retro/storm-cloudy/">Cloudy/Storm ST combo</a>, the <a href="/retro/gotek/">Gotek</a>, the <a href="/retro/ultrasatan/">UltraSatan</a>, the <a href="/retro/sidecartridge/">SidecarTridge</a> and the <a href="/retro/atari-networking-bbs/">Wi-Fi modem</a>. The original Atari keyboard is still used on this machine.</p>
