It matters not
Well done. I am puzzled, however, why anyone would find a need or want to make the case that today's digitized world is largely due to the availability of suitable analog components, even if it is so. The exercise is a bit of a takeoff on comparing athletes (or just about anything) of different eras. For the most part it's not doable, for each has its own unique coordinates in time-space. And often the rules of the game have changed, or latter events are often dependent on former events to complicate the discussion. Or the "judges" have different yardsticks for measuring. For example, who was the greater quarterback, Unitas or Manning/Brady? Who was a greater theoretical physicist, Maxwell or Einstein?

Nice work....
Thanks for that Bill, interesting stuff.  To stay on the subject of cabling, I had in the past to do a fair bit of this at work and it drove me scatty.  At one stage I rewired all our patch panels and ethernet switches so that the switches were directly above the patch panels they were feeding.  I connected switch ports directly to patch panels hence saving a lot of space in our previously way overcrowded cable management trunking.  I had cables custom produced in three different lengths (I think 150, 200 and 250 mm - 6/8/10 ins) to make for an extra-neat job.  It looked beautiful when it was finished, but over the years entropy has crept in.  Rather than wire a new cable to a different port for a special purpose connection (say a SCADA connection instead of the usual corporate LAN) someone would wire in a new cable and disrupt my nice layout.  Or when wiring a connection to the core switch, they'd wire a 3m cable at a crazy angle to reach, instead of getting a 5m cable to do the job properly.  Or (the most heinous crime) the patch panels to the server racks were those v-shaped ones where patch outlets 1-12 are cabled from the left, 13-24 from the right.  To save getting a longer cable someone would cable across the middle.  Eventually I put on a label down the middle "Police line, DO NOT CROSS" and told everyone that if any cable did cross it, it would be removed and I didn't care if a server went down. I only had to do that once!  Fortunately the server was pre-production, otherwise I could have landed myself in hot water.....  It's usually IT guys who are the guilty ones, I've offered to cable anything for anyone anytime, but some of them will still do it themselves.  Grrrr...

And nice blog @Antedeluvian, I'd missed it previously.  A man after my own heart....

Re: Good, Bad, Ugliest cabling
Bill

Thanks for your link to good and bad cabling examples (link added for others' convenience). I did not know there was a publication dedicated to the subject!

I thought I might point out that I did a blog "Tidy Your Wiring" on the same subject.

Good, Bad, Ugliest cabling
For a photo of stunningly nice cabling similar to what I saw at CBS, as well as the worst two you'll ever see (most likely), check out this page from the always interesting "Cabling Installation & Maintenance" publication--always has good "real world" insight:

http://www.cablinginstall.com/articles/print/volume-24/issue-12/departments/infrastructure-insights/cabling-exceptionalism-order-vs-chaos.html

(The online photos have much more resolution that the fairly small ones that ran in print)

Winters are getting shorter and temperatures are on the rise, and I think youíll agree with me that overheating is never a good thing. Whether itís human beings, equipment or pizza, you never want anything to be too hot.
