  1. Modifying an IBM 4869 external floppy box, Part 2

    Okay, now replace the cable retainer (all plastic), making sure to press firmly along its entire length to make sure that all wires have been pierced by the insulation-displacing contacts and that the retainer latches into the connector body:

    Fold the cable over the connector body as it was originally, and replace the strain relief. You may need to bend the ears slightly together to get the relief to latch over the retainer. You'll probably have a bit ...

  4. Hacking a Compaq N410C in order to upgrade to 802.11n networking.

    So I have an old Compaq N410C laptop. Its a nice older laptop (though not vintage). The only problem with it is that it does not have built in wireless.

    I have been using a PC card Linksys A+B card to get in onto my network, but I recently discovered that this card does not support WPA, only WEP. This is no good since my network uses WPA which is much more secure than WEP and most of my other wireless clients have no issues with this.
