To my surprise, the network was passing traffic within seconds of first power on. The Vampire taps had worked perfectly and my terminators appear to have done the trick nicely. Just for kicks, I installed the second Vampire Tap with the network running, streaming video on one of the PCs. Not a single interruption!
I just think it's important to note here the longstanding relevance of both vampires and terminators to the Internet.
Werewolves, however, were pretty much only found on token ring.
A common belief persists that 10BASE5 used RG-8/U cable. This, for the most part, appears to be untrue. The cable used was purpose designed for 10BASE5 and manufactured by Belden under the part number 9880 (A few other compatible cables may exist). The reason #9880 cable was specified is that several variants of RG-8 exist with varying dimensions and manufacturing standards. Given that the main form of connection of MAU's to 10BASE5 networks was by the precisely designed prongs in Vampire taps, cable dimensions and dielectric consistency had to be spot on. [..]
For someone like me who hadn't encountered it before, no amount of looking at pictures could prepare for how big this stuff is. Short of high power transmission cables, it's the largest coaxial cable I've ever seen. It is also very heavy, rigid and the bend radius is absurdly large.
