After seeking some inspiration from his muse, William Shatner, he decides to go all the way back to the beginning of the microcomputer revolution by building a working replica of the O.G. personal computer: the MITS Altair 8800. In this Arduino-based build, he&#39;ll put his love for LEDs and toggle switches to the test during marathon soldering sessions getting all of the external functions of the Altair working accurately so he can play a few rounds of &quot;Kill The Bit&quot; on the front panel.</span></p></td></tr></tbody></table><p style="margin:0;padding:0px;">&nbsp;</p><h2><span style="color:#3334ca;">Supplemental

days&quot; of hobby computing, but he can&#39;t decide which direction he wants to go to fill the retrocomputer-shaped hole in his heart. After seeking some inspiration from his muse, William Shatner, he decides to go all the way back to the beginning of the microcomputer revolution by building a working replica of the O.G. personal computer: the MITS Altair 8800. In this Arduino-based build, he&#39;ll put his love for LEDs and toggle switches to the test during marathon soldering sessions getting all of the external functions of the Altair working accurately so he can play a few rounds of &quot;Kill The Bit&quot; on the front panel.</span></p></td></tr></tbody></table><p style="margin:0;padding:0px;">&nbsp;</p><h2><span style="color:#3334ca;">Supplemental

days&quot; of hobby computing, but he can&#39;t decide which direction he wants to go to fill the retrocomputer-shaped hole in his heart. After seeking some inspiration from his muse, William Shatner, he decides to go all the way back to the beginning of the microcomputer revolution by building a working replica of the O.G. personal computer: the MITS Altair 8800. In this Arduino-based build, he&#39;ll put his love for LEDs and toggle switches to the test during marathon soldering sessions getting all of the external functions of the Altair working accurately so he can play a few rounds of &quot;Kill The Bit&quot; on the front panel.</span></p></td></tr></tbody></table><p style="margin:0;padding:0px;">&nbsp;</p><h2><span style="color:#3334ca;">Supplemental
