  <!-- 2. DESCRIPTION -->
  <div class="pcw-section-box">
    <div class="pcw-section-title">Description</div>
    <div style="color: #aaffaa; line-height: 1.6; text-align: justify;">
      <p><strong>Kempston Data</strong> was the specialized commercial division and one of the most iconic peripheral hardware engineering brands of the 8-bit era in the United Kingdom. Widely celebrated for establishing the absolute standard for joysticks on Sinclair platforms, the company achieved a critical milestone of diversification in 1986 by establishing a presence on the <strong>Amstrad PCW</strong> series. The purpose of its expansions was to deliver high-fidelity physical control interfaces that disrupted the paradigm of a machine purely targeted at offices, opening up the PCW's software catalog to action video games and interactive desktop publishing (DTP) environments.</p>

  <!-- 3. DEVELOPED HARDWARE & TECHNICAL PORT MAPPING (PRESERVATION) -->
  <div class="pcw-section-box">
    <div class="pcw-section-title">Developed Hardware (Specifications)</div>
    <div style="color: #aaffaa; line-height: 1.6; text-align: justify;">
      <p>Kempston's physical hardware catalog for the Amstrad PCW 8256/8512 systems extended the machine's low-level Input/Output capabilities. Their two baseline expansions required for accurate emulation and digital preservation are:</p>
      <ul>
        <li><strong>Kempston Joyce-Stick Interface:</strong> Launched in mid-1986 at an original retail price of £19.95. This peripheral attached directly onto the computer's rear edge expansion bus, offering an Atari-specification DE-9 9-pin controller port. Unlike Cascade's synchronous protocol handling, Kempston's physical board architecture decodes signals by mapping them onto Input/Output port <strong>0A0h (&HA0)</strong> of the Z80 microprocessor.</li>
        <ul>
          <li><strong>Bit Interception Protocol (Native Active High Logic):</strong> When an IN instruction is executed on I/O port 0A0h, the state is returned using active-high logic (a binary value of 1 signals switch engagement or button depression):</li>
          <li><strong>Bit 4:</strong> Fire button. Returns a 1 value when pressed.</li>
          <li><strong>Bit 3:</strong> Up direction. Returns a 1 value when the shaft is pushed forward.</li>
          <li><strong>Bit 2:</strong> Down direction. Returns a 1 value when the shaft is pulled backward.</li>
          <li><strong>Bit 1:</strong> Left direction. Returns a 1 value when pushed leftward.</li>
          <li><strong>Bit 0:</strong> Right direction. Returns a 1 value when pushed rightward.</li>
        </ul>
        <li><strong>Kempston Mouse (The Joyce Mouse):</strong> A pioneering hardware solution targeted at the advanced page layout and Desktop Publishing (DTP) software sector. It featured a three-button mechanical mouse paired with a dedicated bus controller expansion card that streamlined fluid on-screen X/Y coordinate positioning, bypassing the native constraints of cursor keys for professional text block manipulation.</li>
      </ul>
    </div>

  <!-- 4. ASSOCIATED SOFTWARE ENVIRONMENT -->
  <div class="pcw-section-box">
    <div class="pcw-section-title">Support Software & Integration</div>
    <div style="color: #aaffaa; line-height: 1.6; text-align: justify;">
      <p>Kempston's hardware solutions received immediate and massive software ecosystem support from major British software houses. Their unique port 0A0h protocol was directly compiled into the boot loader handling routines of monumental games like the <em>Bounder</em> trilogy, <em>Batman</em>, and Ocean Software's <em>Head over Heels</em>. For corporate environments and mouse deployment, Kempston supplied native CP/M system floppies containing the required <strong>.FIB</strong> extension configuration files to intercept the BIOS, integrating the cursor mouse pointer seamlessly inside professional layout suites.</p>
