The connector on the Amiga 1000 uses crossover wiring, similar to a telephone handset. The connector wiring on the Apple computers, however, requires a polarized straight-through pinout. Using a telephone handset cable instead of the supplied cable could short out the +5 volt DC supply and damage the Apple computer or the keyboard. [12]
The BS 6312 jack has been used in New Zealand since the 1980s, replacing a number of other connectors and hard-wired connections, and was subsequently replaced by a "2-wire" version suited to daisy chain wiring that eliminated the 3rd anti-tinkling wire.

Attached here is the pin-out diagram of the new "skinny cable", only requiring 4-pair Category 3 cable, to each telephone set while providing the same multiline functionality of 1A2 and more. It uses the RJ45 connector to connect each phone (voice terminal) to its associated extension jack on the Merlin control unit (KSU).
Some telephone technicians used mnemonic phrases, such as red-right-ring-rear, or ring-right-red-rough, to remember that the red wire connects to the right-side post in the wall jack and to the ring on the plug and to the rear lug on main distribution frames. Sometimes rough or ridge was added for jumper wires with a tactile code. [citation needed]
