I'm sick of hearing that this proble occured because people were trying to save bytes. I was doing COBOL programming in the 70's, I probably wrote code that would have y2k problems, and saving bytes had nothing to do with it.
The problem arises simply because people (programmers included) normally write dates in the format "mm/dd/yy", as in 12/31/99. Not just in computer programs, but in normal, day-to-day lives. It's that simple, and that is all that there is to it.

Apart from those Digital DCL users who have been using it to invoke command
procedures for about 25 years and TOPS-10 users who used it for I/O
redirection for even longer....

Thanks, I got the pointer for polaroid... I'm going to follow
up on it. As for a vt100 clone -- 1 line of 16 characters?
not much of a terminal... but I guess enough if there isn'
t much data which has to go back and forth...

The blue color of Zenith and some other monochrome LCD displays is caused by the backlight. These displays use an electroluminescent panel behind the entire LCD screen, and it gives off a blue light. Most current LCD displays use flourescent tubes either behind or on the sides of the displays, with a variety of optical diffusers. Flourescent tubes, of course, give off white light.

Anything but rare. It was the development, pre-ICEand eprom version
programmer for the 8048 and 8049 (also 874x) parts. It has asimple debug
monitor and also download capability.
Many are still in use as the 874x parts are still in manufacture and use
for low end controllers.

Y2K computer glitches hit Sweden taxis, gas pumps.
STOCKHOLM, Sweden - For a while, some taxi passengers got unexpectedly
cheap
rides and some motorists had trouble buying gas due to computer glitches
that
accompanied the new year in Sweden.
Stockholm's largest taxi service recently changed the way it calculates
fares.
But when 1998 became 1999, some of its computers didn't adjust properly
and
passengers were charged normal rates, instead of the higher holiday and
late-hour fares.
"The problem has been patched, and now we'll get to the root of the
problem," Taxi Stockholm managing director Anders Malmqvist said in a
telephone
interview Saturday.
Customers of Statoil, Norway's state oil company that operates about
600 gas stations in Sweden, couldn't use their credit cards Friday
because
pumps were programmed to accept them only through December 1998.
"There was nothing wrong in the data technology, but rather it was we
who
programmed badly," Statoil spokesman Henrik Siden told the regional
newspaper
Oestgoeta Correspondenten.
The day before, police at Stockholm's Arlanda international airport
were temporarily unable to issue provisional travel documents to four
travelers
who had misplaced their passports, the Swedish news agency TT reported.
When they attempted to input the date, some computers would not accept
"99" and
transmitted in response: "end of run" or "end of file."
Any addresses to get more info?

No, the only change I've made is to add an IDE 2x CD-ROM drive and install a
copy of Win95.

It may only care about date, but depending on how the application
was written, it may calculate the day of week based on the *date*,
or it could simply count days 1-7 (rinse) and repeat.
If the latter, no problem... if the former, then the programming
will drift over the years, only getting it right again 28 years
later...

The system does not lock if the geometry is poor or the required tests fail.
It's designed to not give error filled results. I'd bet though it will ride
through it with minimal problems as most aircraft GPS use multiple sats and
the really big ones like on Commercial also have inertial systems to check
against. None fly single system and the whiskey compas is still there
to check the tube!
