I am 10 years off on age. DOS was also invented about this same time. The first <a href="http://en.wikipedia.org/wiki/Microcomputer" title="Microcomputer">microcomputers</a> did not have the capacity or need for the elaborate operating systems that had been developed for mainframes and minis; minimalistic operating systems were developed, often loaded from <a href="http://en.wikipedia.org/wiki/Read-only_memory" title="Read-only memory">ROM</a> and known as Monitors. One notable early disk-based operating system was <a href="http://en.wikipedia.org/wiki/CP/M" title="CP/M">CP/M</a>, which was supported on many early microcomputers and was closely imitated in <a href="http://en.wikipedia.org/wiki/MS-DOS" title="MS-DOS">MS-DOS</a>, which became wildly popular as the operating system chosen for the <a href="http://en.wikipedia.org/wiki/IBM_PC" title="IBM PC" class="mw-redirect">IBM PC</a> (IBM's version of it was called IBM DOS or <a href="http://en.wikipedia.org/wiki/PC-DOS" title="PC-DOS" class="mw-redirect">PC DOS</a>), its successors making <a href="http://en.wikipedia.org/wiki/Microsoft" title="Microsoft">Microsoft</a>. In the 80's Apple Computer Inc. (now <a href="http://en.wikipedia.org/wiki/Apple_Inc." title="Apple Inc.">Apple Inc.</a>) abandoned its popular <a href="http://en.wikipedia.org/wiki/Apple_II" title="Apple II" class="mw-redirect">Apple II</a> series of microcomputers to introduce the <a href="http://en.wikipedia.org/wiki/Apple_Macintosh" title="Apple Macintosh" class="mw-redirect">Apple Macintosh</a> computer with an innovative <a href="http://en.wikipedia.org/wiki/Graphical_User_Interface" title="Graphical User Interface" class="mw-redirect">Graphical User Interface</a> (GUI) to the <a href="http://en.wikipedia.org/wiki/Mac_OS" title="Mac OS">Mac OS</a>.

Microsoft responded to this progress by hiring <a href="http://en.wikipedia.org/wiki/Dave_Cutler" title="Dave Cutler">Dave Cutler</a>, who had developed the <a href="http://en.wikipedia.org/wiki/OpenVMS" title="OpenVMS">VMS</a> operating system for <a href="http://en.wikipedia.org/wiki/Digital_Equipment_Corporation" title="Digital Equipment Corporation">Digital Equipment Corporation</a>.

In fact I had a work computer in 1960 that had paper tape storage of everything :-) 73 Karl <pre class="moz-signature" cols="72">-- Karl F.
