Checking my old computer.

[Karl Larsen]

     I have found the floppies and they are 5 and 1/4 inch paper encased 
which were invented in 1976 so my computer had to in the late 1970's. I 
am 10 years off on age. DOS was also invented about this same time.

The first microcomputers <http://en.wikipedia.org/wiki/Microcomputer> 
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 ROM 
<http://en.wikipedia.org/wiki/Read-only_memory> and known as /Monitors/. 
One notable early disk-based operating system was CP/M 
<http://en.wikipedia.org/wiki/CP/M>, which was supported on many early 
microcomputers and was closely imitated in MS-DOS 
<http://en.wikipedia.org/wiki/MS-DOS>, which became wildly popular as 
the operating system chosen for the IBM PC 
<http://en.wikipedia.org/wiki/IBM_PC> (IBM's version of it was called 
IBM DOS or PC DOS <http://en.wikipedia.org/wiki/PC-DOS>), its successors 
making Microsoft <http://en.wikipedia.org/wiki/Microsoft>. In the 80's 
Apple Computer Inc. (now Apple Inc. 
<http://en.wikipedia.org/wiki/Apple_Inc.>) abandoned its popular Apple 
II <http://en.wikipedia.org/wiki/Apple_II> series of microcomputers to 
introduce the Apple Macintosh 
<http://en.wikipedia.org/wiki/Apple_Macintosh> computer with an 
innovative Graphical User Interface 
<http://en.wikipedia.org/wiki/Graphical_User_Interface> (GUI) to the Mac 
OS <http://en.wikipedia.org/wiki/Mac_OS>.

The introduction of the Intel 80386 
<http://en.wikipedia.org/wiki/Intel_80386> CPU 
<http://en.wikipedia.org/wiki/CPU> chip with 32-bit 
<http://en.wikipedia.org/wiki/32-bit> architecture and paging 
<http://en.wikipedia.org/wiki/Paging> capabilities, provided personal 
computers with the ability to run multitasking 
<http://en.wikipedia.org/wiki/Computer_multitasking> operating systems 
like those of earlier minicomputers 
<http://en.wikipedia.org/wiki/Minicomputers> and mainframes 
<http://en.wikipedia.org/wiki/Mainframes>. Microsoft responded to this 
progress by hiring Dave Cutler 
<http://en.wikipedia.org/wiki/Dave_Cutler>, who had developed the VMS 
<http://en.wikipedia.org/wiki/OpenVMS> operating system for Digital 
Equipment Corporation 
<http://en.wikipedia.org/wiki/Digital_Equipment_Corporation>. He would 
lead the development of the Windows NT 
<http://en.wikipedia.org/wiki/Windows_NT> operating system, which 
continues to serve as the basis for Microsoft's operating systems line. 
Steve Jobs <http://en.wikipedia.org/wiki/Steve_Jobs>, a co-founder of 
Apple Inc. <http://en.wikipedia.org/wiki/Apple_Inc.>, started NeXT 
<http://en.wikipedia.org/wiki/NeXT> Computer Inc., which developed the

     So it is sure the computer was closer to 1980 than 1960. In fact I 
had a work computer in 1960 that had paper tape storage of everything :-)
