Apparently an old-style French phone cable. For phone uses, it is:

1 grey

2 transparent/pink

3 white

4 brown

5 blue

6 yellow

7 purple

8 orange

Looks like that pairing is unsuitable for Ethernet, so I'll use something else.

Now that I know this cable is called PTT-298, I found that apparently lots of people managed to get 1 Gb/s Ethernet working on it.

I think I'll just match colors as far as I can:

1 White

2 Grey

3 Yellow

4 Blue

5 Pink

6 Orange

7 Purple

8 Brown

Then I basically only need to remember that Grey is Green, and otherwise just use the colors as I'm used to.

The pairs are grey/white, blue/pink, brown/purple, orange/yellow.

There is one twist per 1.5 cm.
