  Computing: A New Tool for Fundamental Physics (1984)
Computing is still not considered part of theoretical physics education, even though so many trained in physics go to computer-related jobs in industry.
When computer programs are used in an exploratory fashion for fundamental research, the real time spent in their development and debugging is usually a thousand times larger than is taken for their final execution.
Of course, using computers, unlike using mathematics, costs money: but it is essential to the advancement of theoretical physics that almost every theoretical physicist get a computer, to use interactively as an integral part of their research.

 Blit (computer terminal) - Suprari (beta)
In computing, the Blit is a programmable bitmap graphics terminal designed by Rob Pike and Bart Locanthi of Bell Labs in 1982.
Acting initially as a "glass Teletype" ASCII terminal, after logging into a Unix system a window manager could be downloaded, with each window attached as a separate pseudo-terminal on the host system (multiplexing the serial-line connection).
The Blit was commercialized as the AT&T/Teletype model 5620, followed by models 630 and 730.

Also, the TV Typewriter was not entirely usable as a terminal, because it was a paged display system; when you got to the end of one page, and that last character went up on the screen, you had only one-thirtieth of a second before the screen blanked and you saw the next [character].
I asked Don, "Why did you do it this way if it's supposed to be a computer terminal?" and he said, "It isn't supposed to be a computer terminal, people just want to put up characters on their TV sets." And he was right.
Eckert was a lifelong computer engineer, continuing in consulting work until shortly before his death; but his name is most often associated with his trailblazing work on problem solving in ballistics, between 1943 and 1946, which culminated in the creation of the ENIAC computer at the Moore School of Engineering, University of Pennsylvania.

Computing Science Staff are now under so much pressure from increased student numbers and the need to do well in research assessment that they have little time (and no obligation) to help their service colleagues.
Although we did not dare, in the end, to move to fully distributed computing in the 1985 procurement, the seeds were already sown.
Computing Science Teaching has been dominated by change, both in the subject matter we teach and in the types of courses and students.

In the world of personal computing, bare metal programming (especially in sense 1 but sometimes also in sense 2) is often considered a Good Thing, or at least a necessary evil (because these machines have often been sufficiently slow and poorly designed to make it necessary; see ill-behaved).
Most computer languages provide a kind of data called `integer', but such computer integers are usually very limited in size; usually they must be smaller than than 2^(31) (2,147,483,648) or (on a bitty box) 2^(15) (32,768).

 Klass Of '99 - Spectrum Conversion.   (Site not responding. Last check: 2007-10-29)
I've (finally) fixed the "dirty" blit to only update the necessary parts of the screen, which speeds it up a bit (doesn't fix the slow scrolling though and I can't get a proper screen grab of it).
I made the terminal the full text width of the original, but this practically negates the need to update the sprites at the sides and covers up the number of lines (or where they will go eventually)...
Blitting the full screen wastes up to two frames (I guess) as you have to let the scanline pass you before you start to copy anything.
