Are you serious? Look up the old arcade game Tempest. That had red, green and blue objects.

But were the lines continous, with no breaks caused by as shadow mask?
If they were: Can you provide a reference to a description of the technology, how they did it?

I'll try looking it up a little later and post back if I find something.
But as I recall, the lines were continuous.

While a proper driver would scan the screen line by line, in principle it could let the beam trace any path, drawing "true" vector lines, in the same pattern as you would on a Tektronix screen.
Not entirely accurate. You could do that only on CRTs with electrostatic deflection. The more common ones used as PC monitors had electromagnetic deflection with those big coils installed on the neck of the CRT. Trying to move the beam randomly on those was impossible due to the high induced voltage. For regular scans (CRTs and TVs) the horizontal fly-back was used to produce the high voltage for the secondary anode.
The electrostatic CRTs (like the ones used in scopes) had the drawback of a limited deflection angle, at least for any pretense of linearity and that made those very long necks.

I am old enough to remember Vector Graphics, the PC's and the company. I was a dealer until they went out of business.

Oh wow. Do you recall a home entertainment device named Vectrix? I think it was a game console with its own CRT display.

If you remember how they were drawn then you will likely understand why vector graphics displays no longer exist. Originally, the vectors actually aimed the electron gun to draw the image. Instead of left-to-right, one line at a time drawing as a traditional CRT did, vector graphics displays actually aimed the beam to draw each of its lines. Since we no longer have CRT displays manufactured in any significant number, if at all, that just doesn't happen any more. As mentioned, the mathematical constructs are still with us but image drawing is done in a completely different way.

"Real" vector graphics only work on (special) CRT displays (and other hypothetical beam-steered displays), the lines are never converted to pixels, they're drawn with the screen itself. If drawing lines on a grid of pixels is also "vector graphics", then you're looking at it right now.

after 8 years, I dumped current modem and bought a new one.
it is ARRIS G34 with WIFI router. I need faster Internet service now: download speed up to 1Gbs...
diligent hands rule....

Congrats! Can your internet service supply such a high download speed?

yes, absolutely. My monthly fee keeps going up and I called the internet service company.
if I upgrade my internet service package, I can lower my cost...

Beware of those kinds of deals. I bought such a deal, and when the promotional period expired, my price went up tremendously.

it's their marketing trick. I have to call them every year, otherwise my fee keeps going up.
also I need faster service to download financial data for my data mining application.

With XFinity at least (US) you can negotiate with them when this happens. Make sure you have an alternative service to jump to and then tell them you will switch. They'll extend the "promotion"
You can do this every year or so.

I second that.
Some years ago, I was told, awards were given to the movies with the most convincing animal costumes. This was at a time when 2001 certainly would have been eligible, and critical voices asked why 2001 wasn't even nominated. The nomination committee replied that the awards were for the best animal costume, not for movies showing well trained real animals.
The good thing about outdated technology, such as DVD/BD, is that if I make a reference to 2001 (say) to some kid whose father wasn't born when the movie came out, I can walk over to my bookshelf to fetch the movie and slip it into the player, to let the kid see what it is all about.
For its day, the movie is truly impressing. Really worth watching, but if you do, watch it as a 1968 movie, not as a 2022 one!

That movie felt like it lasted 2001 years.
Most boring movie ever.
I respect that it was amazing in its time, but as far as I'm concerned it really didn't stand the test of time.
Maybe my expectation were too high, since everyone and their dog regards it as one of the best movies ever, which also makes it one of the most overrated movies ever.
Wouldn't recommend it except to mess with someone I don't like.
The soundtrack was awesome though.

Sure, judging a 54 year old movie by criteria applied to 2022 movies (or even 2021 ones) is bound to lead to a somewhat negative verdict.
That certainly doesn't mean that modern movies are "better". They are just different. If you don't know the language of modern movies, they are boring as h**^*. It is a matter of understanding the language.
You may suspect that I am bored by a lot of modern movies. You may very well be right.

It's not even that I don't like old movies.
I like plenty of old movies, older than A Space Odyssey even, just not A Space Odyssey.
Recently, I watched Metropolis, a 1927(!) movie.
Sure, it looks dated, it's a silent black and white movie even, yet it had more story, more movement, some great stills, and Moloch (  )...
I feel as though A Space Odyssey is mostly appreciated for it's Windows 95 screensaver special effects which were probably great at the time, but can't convince a younger audience.
The intro with the black stones and the apes is just booooring, goes on for like ten minutes without anything happening, except some apes sitting near a stone.
Maybe I'd like it more if I watched it now (watched it some ten years ago), but I feel as though I've wasted enough of my life on that movie

I was across the pond when 2001 came out so I didn't get to see it until many years later but I was very impressed.
