<p><b>System Modules</b> (originally known as <b>System Building Blocks</b>; the name was changed around 1961) are a <a href="Digital_Equipment_Corporation" title="Digital Equipment Corporation">DEC</a> modular <a href="Digital_logic" class="mw-redirect" title="Digital logic">digital logic</a> family which preceded the later <a href="Flip_Chip_(PDP_module)" class="mw-redirect" title="Flip Chip (PDP module)">FLIP CHIPs</a>.<sup id="cite_ref-DECLogicp56_1-0" class="reference"><a href="#cite_note-DECLogicp56-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> They connect to the units they are plugged into via a set of 22 gold-plated discrete pins along one edge.<sup id="cite_ref-SysModvii_2-0" class="reference"><a href="#cite_note-SysModvii-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup>

</p><p>They use <a href="Transistor" title="Transistor">transistor</a> inverter circuits, with the transistors operating saturated, to avoid dependence on tight tolerances; they use -3V and 0V as logic levels. Intended for prototyping as well as production, they include design features intended to avoid damage. They are provided with design advice which includes loading rules and wiring instructions.<sup id="cite_ref-SysMod4_3-0" class="reference"><a href="#cite_note-SysMod4-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup>

</p><p>They were available in several compatible speed lines:

</p>

<ul><li>4000-Series: the second series, nominally 500 KHz, but some 1 MHz<sup id="cite_ref-SysMod6_4-0" class="reference"><a href="#cite_note-SysMod6-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup></li>

<li>1000-Series: the original series, nominally 5 MHz<sup id="cite_ref-SysMod7_5-0" class="reference"><a href="#cite_note-SysMod7-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup></li>

<li>6000-Series: higher speeds, nominally 10 MHz<sup id="cite_ref-SysMod8_6-0" class="reference"><a href="#cite_note-SysMod8-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup></li>

<li>8000-Series: very high speeds, nominally 30 MHz<sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup></li></ul>

<p>In addition, special modules were available for purposes such as <a href="Input/Output" class="mw-redirect" title="Input/Output">Input/Output</a> (I/O) converters (to standard internal voltages), bus drivers, lamp and solenoid drivers, <a href="A/D_conversion" class="mw-redirect" title="A/D conversion">A/D conversion</a>, relays, <a href="Magnetic-core_memory" title="Magnetic-core memory">core memory</a> drivers, etc.<sup id="cite_ref-SysMod9_8-0" class="reference"><a href="#cite_note-SysMod9-8"><span class="cite-bracket">[</span>8<span class="cite-bracket">]</span></a></sup>

</p><p>Larger assemblies which are part of the same family provide core memory testing devices. There are also power supplies, mounting panels with slots for the modules, cabinets to hold groups of mounting panels, indicator light panels, etc.<sup id="cite_ref-SysMod10_9-0" class="reference"><a href="#cite_note-SysMod10-9"><span class="cite-bracket">[</span>9<span class="cite-bracket">]</span></a></sup>
