|
||
<a href="../T/timesharing.html"><i class="glossterm">timesharing</i></a> real. It looms large in hacker folklore
|
||
because of its adoption in the mid-1970s by many university computing
|
||
facilities and research labs, including the MIT AI Lab, Stanford, and CMU.
|
||
Some aspects of the instruction set (most notably the bit-field
|
||
instructions) are still considered unsurpassed. The 10 was eventually
|
||
eclipsed by the <a href="../V/VAX.html"><i class="glossterm">VAX</i></a> machines (descendants of the
|
||
<a href="PDP-11.html"><i class="glossterm">PDP-11</i></a>) when <a href="../D/DEC.html"><i class="glossterm">DEC</i></a> recognized
|
||
that the 10 and <a href="../V/VAX.html"><i class="glossterm">VAX</i></a> product lines were competing
|
||
with each other and decided to concentrate its software development effort
|
||
on the more profitable <a href="../V/VAX.html"><i class="glossterm">VAX</i></a>. The machine was finally
|
||
dropped from DEC's line in 1983, following the failure of the Jupiter
|
||
Project at DEC to build a viable new model. (Some attempts by other
|
||
companies to market clones came to nothing; see
|
||
<a href="../F/Foonly.html"><i class="glossterm">Foonly</i></a> and <a href="../M/Mars.html"><i class="glossterm">Mars</i></a>.) This event
|
||
spelled the doom of <a href="../I/ITS.html"><i class="glossterm">ITS</i></a> and the technical cultures
|
||
that had spawned the original Jargon File, but by mid-1991 it had become
|
||
something of a badge of honorable old-timerhood among hackers to have cut
|
||
one's teeth on a PDP-10. See <a href="../T/TOPS-10.html"><i class="glossterm">TOPS-10</i></a>,
