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>.

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

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

    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 :-)
