	This simulation allows to experience the 1960's mainframe feeling. <br />
	It behaves similar to an original 
	<a class="link" href="https://www.ibm.com/legal/copyright-trademark" target="_blank" rel="noopener noreferrer">IBM</a>
	1401, introduced 1959 and available until 1971. <br />
	This was the introduction of midrange computing opposed to the big irons, but <br />
	nevertheless it allows you not only to watch some demos, but also do some computing<br />
	yourself, including writing programs, handling tapes, and punching cards. <br />
	<br />
	See the
	<a class="link" href="m_youtube.html">YouTube</a>
	channel for some demos<br />
	<br />
	Use the menu on the left to download the simulation to experience it yourself <br />
