The Original Ethernet Cable And Cable Diagrams

BoingBoing Gadgets found this photo of the original original Ethernet cable at Xerox PARC, devised by Bob Metcalfe so he could rig up a local system of sharing things digitally.

The diagram below illustrates part of what he tried to set up. What it doesn’t show, unfortunately, is how slow the network would have been compared to the average home network now. In your face, Bob. [BBG]

    We had those cables connecting the two computers in my parents house circa around 1996.

    @K_dawg: Not my hometown, but the comment is relevant when the town is ultimately responsible for the existence of the post. The company is Xerox, no matter where it is, it all started in Rochester.

    @CaptainHoratioMcCallister: Again I point out that PARC is in Palo Alto, not Rochester. Hometown pride is fine and all, when its relevant. To this post, its really not.

    He didnt even use Microsoft Visio to do the diagram. How unprofessional!

    @daqman: Luckily I didn't have to deal with thicknet. I *did* have to deal with thinnet, and both passive and active star networks (Farallon gear for the AppleTalk network).

    I took an AppleTalk packet analysis course from Kurt Van Der Sluis (one of the guys that helped design the Farallon LocalTalk gear).

    Mmmmm, 230kb/s AppleTalk network over silver satin (daisychained). Those were the days.

    I was working at HP's RF/Microwave lab when they brought it by for us to test. I remember drilling holes into the coax cable to put it on the Time Domain Reflectometer.

    @daqman: He's half right. That pic shows two 10b5 runs going into each end of a BNC tee. My guess is that a 10b2 AUI media converter lived in there.

    @ISOHaven: nope, 10Base5, thick ethernet. What you refer to is what we used to call thin ethernet. Ahh, those were the days, we used to live in a cardboard box in th' middle o' th' road...

    @daqman: Once, in the early 90's, I was onsite at Zenith's offices just outside Chicago (before they were completely taken over by LG). They still had quite a bit of coax in there. We were trying to figure out why this one section one of the floors couldn't talk to the network, and we saw a weird reflection on the scope that the (much more experience at the time) guy I was working with said he'd never seen anything like it. Eventually I found a little magnet with a clip, which someone had used to clip papers to the cabinet over their cubicle, had fallen and was resting against one of the connectors linking two segments of the network!

    @yungjerry703:
    Actually, it did pan out - it's just that it has matured quite a bit since then.

    @NurseDave: You can either alternate the water pressure, or send a spurt to the other computer.

    Half second spurt of water = 0, full second spurt = 1. Or 20 PSI is 0, and 30 is 1. Or however you want to work it out so it works good.

    @CaptainHoratioMcCallister: I don't think NY really has ever had a horse in the 'Best Sub' race... We're content knowing we have the best everything else.

    But, for the record, a turkey Shorti from any WaWa on the East Coast is the best hoagie around. And yes, it's called a hoagie.

  • ISOHaven

    Looks like normal 10Base2 to me. Been there, done that.

    Just looks like the cable has more shielding.

    Umm I'm sorry. I'm a huge dork. That photo reminds me of the scene in Space Camp where Max and Andie are trying to hook up the oxygen tank to the space shuttle.

  • Act Now and get a 4th Celebrity

    @daqman: I'm thankful that by the time I hit networking that the world was busily shifting from Thick/Thin (10base2) net to 10baseT instead.

    Then again I remember crawling along the cable tray 40' up dragging coax behind me. Eventually I just started tying a string to a remote control 4x4 pickup (needed the wheel clearance) to pull a leader string, and then ran the cable that way instead.

    At NASA we deployed thicknet with vampire taps and repeaters. Now that was fun!

  • Act Now and get a 4th Celebrity

    @NurseDave: That's not a water line, it's a very large coax cable (thicknet)

    @CaptainHoratioMcCallister: Uh, what does Rochester, NY have to do with anything here? The PARC in Xerox PARC stands for Palo Alto Research Center, as in Palo Alto California. Nowhere in this entire post is Rochester NY mentioned.

  • I see the light. It burns!

    So that's also the worlds first wireless network. Wonder how the computer's handled that 13-bit WRS(Wireless Radio Scramblatron) security.

  • daqman

    Hah! I remember working at CERN in 1989. There was trouble with the ethernet network. In those days you made a connection to the CERN "Backbone" by putting a special clamp around the thick coax cable, like the one in the picture, that had two spikes that punctured the insulation. One was short and made a connection with the grounded sheath the other was longer and reached to the core. A very delicate beast. What we found was that some enterprising physicists had tapped into the backbone using two blocks of wood and a couple of nails. It worked for them but caused terrible signal reflections that screwed anyone upstream.
