If you hold down the shift key and type a couple of letters fast
e.g. L and P, sometimes you will get a phantom null (^@) keypress
between the letters. Has anyone else encountered this? The easiest
(and safest) way of doing this is to get into a command line interpreter
and try it; you should get a line like:
{d} LPLPLPLPL^@PLPLPL^@P
if you type fast enough. (I tried it with Mark Williams shell)
I first met it while typing HLP in me3.7 using the shift key instead of
caps lock. What happened was the help screen would get called up! I
suppose this was because the help function was bound to some function
key, and the phantom keypress had the upper 8 bits of the word set to some
garbage. Actually sometimes the computer crashed, and I lost about
fifteen minutes typing the first time; most irritating.
I assume the driver software could not keep up with my typing and the
extra processing involved with the shift key press (see, even 68000s can't
keep up with my typing:- has anyone had this sort of problem on a Cray? 8^).
Any comments? Atari?
