  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:

  2. How to build your own homebrew computer: Make a prototype

    So you've scoured the internet and found just the right schematic for your first homebrew computer. Now you want to build it yourself and are wondering how to go about making the circuit. There are many options but three very common approaches you might consider. Let's pick this one for example:

    I found an ATX PSU with a small form factor. A single Disk Drive power ...
  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.

    So its off to Google to do some ...
