+    <p><strong>[ TECHNICAL SPECIFICATIONS AND HARDWARE MAPPING ]</strong></p>
+    <p>At the low-level hardware architecture tier for the Zilog Z80 microprocessor, the hardware interface responds directly to a fixed Input/Output (I/O) address mapping. The digital joystick signals adhere to the classic Atari DE-9 9-pin standard. It reads input data utilizing an active-low (0) logic implementation, which means that when a directional switch or physical button closes the circuit, its corresponding register bit drops to a binary 0.</p>
+    <ul>
+      <li><strong>I/O Port Address:</strong> <code>0E0h</code> (Equivalent to <code>224</code> in decimal format).</li>
+      <li><strong>Native Software Support:</strong> Notable software titles like the official conversion of <em>'Head over Heels'</em> by Ocean Software natively integrate specific reading routines targeted exclusively to port 0E0h. Due to this hardcoded port register assignment, this particular control routine is entirely incompatible with competing standards such as the Spectravideo interface.</li>

+    <p><strong>Modern Emulation & Preservation Systems Support:</strong></p>
+    <p>The exact hardware specifications of the Cascade Joystick standard (often referenced programmatically as "JoyceStick") are fully documented and replicated across major software and hardware preservation systems:</p>
+    <ul>
+      <li><strong>CP/M Box (by Habi / Habisoft):</strong> This modern Windows emulator provides native plug-and-play support for the Cascade standard. It captures host system Gamepads or Joysticks, automatically maps X/Y axes and the first two physical buttons, and digitally processes them to emulate the precise port behavior of the original PCW peripheral.</li>
+      <li><strong>Joyce:</strong> Developed by John Elliott, this emulator cleanly replicates the execution behavior of the Z80 <code>0E0h</code> I/O address space.</li>
+      <li><strong>MiSTer FPGA (Amstrad PCW Core):</strong> The platform features pure logical hardware gates recreation for the Cascade layout alongside Kempston, Spectravideo, and DK'tronics architectures.</li>
