The floppy power cable was supposed to be fool-proof. The keying is done
by the PCB on the bottom edge. Well, it ain't damned-fool proof! ;-)
Data cables are a whole 'nother kettle. No one can agree on how they
should be keyed. Though it seems that the 80-conductor ATA cables have
finally gotten it right.
Yeah but isn't it funny how they always seem to go into the keyed mbrd
connector with the ribbon pointing the wrong way so you have to make extra
folds to get it to go where you want neatly. I still remember admiring
the beautiful cable folding used in a genuine IBM PC/AT we got years ago -
every fold just exactly right for routing around cards and devices.
I thought all LCDs had this problem. I certainly see the negative=image
if I view my THinkPad's image off-axis (enough). I assumed that this was
an artifact of the LCD twist/polorization. I can't imagine LCDs for such
use anyway. OTOH, they're *excellent* for CAD apppplications, as long as
they gots all dots.
The TN LCDs are all subject to that syndrome but to varying degrees. The
err, quest for speed to leverage the game market has led to it getting
worse apparently... not sure what the tech details are but the faster the
response, the worse it seems to get. Whether it's a natural result or just
the designers ignoring one criterion to get the best out of the principal
target, i.e. fast response, I dunno.
There are two other common LCD "types", VA (vertical alignment) and IPS
(in-plane switching), with variants on both, which give good off-axis image
and color. Samsungs PVA screens are really good on everything except
response - no detectable color shifting off-axis at all and good tonal
spectrum... not sure how amenable the VA is to improving response but I've
read that it is more complex to produce.
Are the screens really good enough to see the difference? What's the
color tracking across the screen? Do graphics/pre-press people use LCDs?
There are some graphics and photo editing people who are getting
enthusiastic about LCDs but AFAIK, only the very top end most expensive
models but the stigma is slowly being overcome. The market is, of course,
following the money, which is understandable but it seems a shame that, as
a result, the worst of the current technologies, as far as image quality
goes, is winning. It doesn't help that the vendors are quoting specs which
are just not true.
