That would be with SMP (Symmetric Multiprocessor) extensions. The original original was for single processor machines.
Apple has a brilliant design solution. On MacBook Pro laptops, the power button is flush with the deck so it is very hard to press accidentally. A single press brings up a dialog box asking if you want to restart, sleep or shutdown. Hold the button down about 10 secs and you get a forced-restart.
Option-Cmd-Esc brings up the “Force Quit Applications” dialog box to quit the rate hung app.
Dad’s first 286 back in 1987 or so had a gang outlet surge protector thing... with a large toggle switch on the side... not a rocker... a toggle. The stupid thing sat on the floor and if you move your foot to the side like as if you were turning 5o get up fromnthe desk. WHAM! Lights out... and you just lost the last 3 hours of AutoCAD drawings.because you forgot to save.
Holding Ctrl-Alt-Del will soft boot the CPU.
Ctrl Shft Arrow in Excel = useful.
We had a workstation that would access a local tower or a mainframe... and you could toggle back and forth by hitting scroll lock, scroll lock, 2. The guy who set up the box pick scroll lock because it served no other purpose.
Someone should tell Obama and Ex-Secretary of State Clinton and current Secretary of State Kerry that in reference to the Benghazi survivors.
Actually, at one time the scroll lock key served a useful purpose when computers displays were slower than human reaction times. Under DOS one could print a file or directory listing to the screen. . . but if it was too long, a judicious use of the scroll lock key would interrupt the flow of data, stopping the screen from scrolling so the user could read the data before it scrolled up and outta sight. Another tap of the scroll lock key would resume the data flow and the scrolling, filling the screen with data until the next tap. Today, if you try that, the processor is so fast, the data fills far too fast for any human to stop it in any reasonable reaction time. It’s better to page the data.
I do remember those days when scroll lock served a purpose.
Another “weird” key is the Print Screen key... but I use Ctrl Print Screen for screen captures to paste into Paint.
He's a really, really good typist.
Your years are off somewhere. Probably by about 3.
The IBM PC came out in late 81. I bought one as an engineering student on a university discount deal in May of 82. I financed it like you would a car (my car was paid for). It was a good investment.
thanks shego.
