strange cable?

[Micky]

A friend gave me what looks like a network cable, with a modular plug
with 8 slots, but the only ones with wires are slots 1,2,3 and 6.

What is this cable meant for?

RJ-45 plug has 8 contacts (slots?), and wiring only 1,2 and 3,6 pairs makes a
10 Mbit/s cable, either straight or crossed.
It could be made to connect an old 10 BASE-T network card or it's just a
leftover from the previous century.

Fast ethernet (100Mbps) only uses pins 1, 2, 3 & 6, all eight are used
for Gigabit ethernet, do the pairs cross over 1/2->3/6 or straight
through 1/2->1/2?

I translated the word from the Abysinnian. That's what we say there!

Or maybe that's what they say at the Abysinnian Flamingo Casino in
downtown Djibouti.

It's pretty old. I think my friend brought it over last year
complaining it didn't work on his Mac. Of course that doesn't explain
why he had it. I just gave him another cable and didn't look at his
much until the other day. I wish I could tell him what I just
learned but he died last march at 78.

Thanks Frank and Andy, and Jack for trying.
