The "braid terminators" on the AMP taps are little pieces of spring
metal with teeth on them that are supposed to bite into the cable
shield/braid to make a good cable ground (NOT building ground, pul-eez).

The AMP-style taps are supposed to come with 3 or 4 of these thingies,
because they're only good for ONE use. You should use a fresh one if
you ever move the tap.

Besides DEC and Interlan (AMP tap) and 3com (in-line with cable), you might
want to check out transceivers from TCL Incorporated, 2064-B Walsh Ave,
Santa Clara, CA. 95050 Phone:(408)727-3800

This isn't an ad, but they seem to consistently get left out of the
discussions, and they WERE after all the first volume manufacturer of
the 3 Mbit devices and are still Xerox's biggest supplier for the 10 Mbit
transceivers.

They use a modified Gerrold CATV tap, wherein the transceiver screws
onto the tap after the cable's been prep'd. The old stinger got a bad
reputation for opening up when people wiggled the cable a lot(!), but for
about $5 more they now sell you a "new improved" tap with an "Energy
Stinger" (spring loaded) which is said to completely solve the problem.
The price isn't bad, either: $232.80 (quan. 1) for the new transceiver/tap.
They also give good quantity discounts: 30% @ 100, 35% @ 250, 40% @ 500.
