I'll still sell you my used one for $30.

 

perhaps you can sell it for more than new by calling it "well seasoned"

 

lol, right there at the beginning - "We're not at ******* KAF!" and then I didn't understand the next part he said.

 

Am I wrong in guessing the boot band is to keep **** from crawing up your pants/down your boots?

 

that and to keep the excess pantleg from catching on something, along with looking snappy...



...the original way was to tuck the pantleg in the boot, but the strap makes it easier.

 

 

Crooks that got their sag on. You gotta love em...

 

Yep. Used to not mess with blousing straps/boot bands, but the material on the inside of my Khybers -



is like a sawtooth and will "eject" my pants from the boot opening. So blousers it is.

Amazing how little progress we have made as a species in some regards. Minsky's hackers at MIT did that on a PDP-6 in 1968.

 

But did it also make & deliver coffee?

 

I don't believe that it made coffee.

But it is really astounding just how much neat stuff those folks were able to do on what, by today's standards, were some astoundingly primitive machines. For instance, the Sixes had an 18-bit address space (and the high-moby / low-moby paging mechanism wasn't invented until the Ten) so the maximum memory on one was only 256k (where k = kiloword, slightly different from a kilobyte, but functionally similar) and most machines were configured with far less than that; RAM in those days was magnetic core- big, heavy, and obscenely expensive.

Performance-wise, a Six ran at about 0.25 MIPS. For comparison, the original IBM PC, running at 4.77 MHZ, did 0.33 MIPS. (The machine I'm typing this on tips the scales at a little over 4,000 MIPS.)

Anybody here think they can write a ball-catching routine in 256k on an 8086 machine? To me, that's a pretty damn big achievement. I'd love to know how much processing power the designers of that robot wasted to make it do the same thing.

And, since this is a picture thread, here is a PDP-6:



And here is the actual robot arm that caught the first ping-pong ball:

 

I am definitely from the 'new skool' as far as computers go, but it amazes mw how many people forget the fundamentals. At work right now we have discovered a problem with our system where there is one or more delays in the electronics from the physical position and sensors to the a/d conversion and amplification. This can be 'programed out' using either an insane amount of complex math that is a more general solution that will take more (even if not alot) computing power OR identifying the independent variables and applying an independent empirical solution, ie advance value x by t seconds and y by t sec, etc. I think the thing you posted would use the later method of PID control and collection vs. correction it with raw computing power as is commonly done now days....

sometimes simple can be good too.

That, or if the delay is a constant, then just delay whatever other signals surround it by running them through a needlessly long piece of wire. This method was actually in common use in many machines of the era. The propagation delay through copper wire is about 1ns per foot. Most (all?) early computers took advantage of this fact, which was simple to implement as their backplanes were all wire-wrapped to begin with. This is the reason that the inside of a CRAY-1 looks like a complete rat's nest.



Lastly, to keep up with the spirit of the forum, here is a naked man humping a PDP-11, which was the last series in the PDP family, and the progenitor of the VAX, one of the most popular large computers of the 1970s and 80s.

 

Wife shared this one that she got a kick out of. Prince Harry's reaction is hilarious.

 

weeeeeeeeeeeeeee

 

Um...
