The Visicalc clone by Microsoft was MultiPlan; it was Mac users of Excel that convinced 'em to start over as they Windows-ed up their application, and Excel 2 for Windows was their first Intel-processor release. Apple's big win came with LaserWriters that could do the WYSIWYG thing, along with inexpensive local networking.
Wrong. Crimping and welding are both entirely acceptable for high reliability, with solder just a little behind. Wire-wrap is a variable entity, because there's lots of wire and lots of posts, and some combinations are just dandy, like crimping.
A PC power supply is always two or more circuit boards, because the required components aren't reliably joined under ONE solder temperature profile, you gotta use two or more different soldering methods to mass produce 'em. Solder, when it works, is cheap, not excessively reliable.
Commander Kinsey is almost as enthusiastic as Flyguy at reminding us how far he has descended into senile dementia.
Serious computing used to rely on Unix (and even odder operating systems) but now the Linux toolbox has everything that anybody would need.
You do have to understand at the level you need to, which always turns out to take some work, but thick glasses and odd haircuts are always entirely optional, unless you have to send the kinds of signal that dim clowns like Commander Kinsey can recognise.
Except wire wrap isn't just touching. The posts are square and the wire wrapped under tension so the post corners bite deeply into the wire and the torque built up in the post maintains constant high pressure gas tight cold weld contacts. Dozens of them all in parallel. Wire wrapping can be more reliable than soldering over temperature cycling. Voyager and Apollo used a lot of wire wrap. And it is very quick - I used to wire wrap prototypes faster than I could solder and needs no defluxing after.
Are you saying NASA flew wire wrap in space missions? While wire wrap is a solid connection on earth, I would be surprised that it survived the vibration tests. I suppose a couple turns of insulation would prevent the first bite into the wire from braking. I've seen that happen on wire wrap when the wire was not inserted in the tool properly. The whole thing is pretty heavy too. I've got an old wire wrap board from one of the big name prototype board makers (I can't recall the name). It has a bunch of pins for mounting 16 pin chips (and a few 14 pin I think) with power and ground already connected. I don't recall if they had bypass caps or not. The board is rather thick to hold the pins solidly. Between the pins and the board, it weighs a ton.

Well, these are Sony 'starlight' SUPERHAD 0.01 lux PAL/NTSC cameras, need no IR LEDs, can see in the near dark, I use those for many things (shooting down F35s comes to mind).
USB cams over twenty meters or more cable?
I have 9 virtual desktops, 1 has some icons you can click on, one has a browser, one has a Usenet newsreader, one has an audio mixer, and 8 actually have a terminal. GUI is for dummies, like going to a supermarket and searching on the shelves for what you need from what is plonked down there. My computah speaks English and I can just type commands. Much simpler and faster than mousing around in menus (if what you want is there at all). Of course you need to know Unix... It is like going to a hardware store and asking 'I need this' and the guy will get it for you. But of course you need to know about what you want, Maybe in the US these days reading and writing is on the way out (if it ever was in there ;-) ) and people will carry a book with pictures and take it and point to one to commie-nukate or whatever it was . Its a SLOW way, but was already used in the [flint]stone age as drawings on rocks have shown.
Some people read comics (like poopeye), some read datasheets, some read code, and some just read what their computah says.
Yep, for example the Apollo Guidance Computer backplanes. I saw a magazine article circa 1972-3 on the deep space interplantery missions, eg. mariner,pioneer,voyager and there was a photo of the ww-boards undergoing final visual inspection.
Of course modified wrap was used, never seen regular wrap in real life for exactly the reasons you gave.
Perhaps you are short sighted and took your glasses off.
(Wasn't there a disc jockey who got into "trouble" for saying, "I feel like a 16-year-old boy... but where can I get one at this time?" (That would be legal now. I hope Gordon Brown apologised.))
Yeah the low lux would be nice. I tried IR but couldn't find a bright enough IR light. Considering just a PIR powered white light.
But I'm guessing you paid a lot for a Sony camera.
I could do 100m if I wanted, what makes you think this is a problem?
Can't you afford real ones? I just have 5 monitors. I can see them all at once.
It's the way the human mind works, at least normal ones. If I showed you 50 pictures and asked you to find the widget, you could do it far faster than finding the word widget in a pile of 50 words.
It isn't English.
Menus make it easy to find things. For common stuff keyboard shortcuts are always available.
No need to learn that shit.
If I want a 7mm widget, maybe they have a 7.2mm one which would be better. Maybe the guy is busy, maybe he doesn't know exactly what I need. Very easy to walk down the aisle that contains widgets and pick the one I need. The largest part of the human brain is devoted to sight.
No, I don't need any glasses. Why would I need to be short sighted to focus on something close? What's the closest you can focus? I can focus an inch from the end of my nose. Not that I needed to move that close, you must have really low resolution retinas.
It's not legal in the USA in half the states. Did it used to be illegal here?
Surely reading glasses don't just magnify, they change the focusing distance. Someone who needs reading glasses is usually long sighted, so it needs to look to their eye as though the book etc is several feet away. Not necessary with a magnifying glass.

Well, what's a lot? about 35 USD
Lots of loss in voltage over USB cables. google: 'USB maximum cable length'
No need for that,
I can tyoe 'widgetENTER' faster than you can find the icon, even without looking. On top of that I use zsh as shell, so usually if I did use a command before it is just cursor up a few times and ENTER, or the first character of the command, cursur up ENTER
You can make it as English (or any other language) you want by writing scripts for more complex stuff I have many of such scripts.
Very true however solder joint fatigue and cracking over extreme temperature cycling was an even more serious problem. Back in the day many studies placed wire wrap well ahead of solder for reliability. One of the (few) benefits of RoHS is that lead free solders tend to perform better over extreme thermal cycling.
