I have updated Golden Eye of the Kobold King, my first Swords & Wizardry WhiteBox release from last summer. I made some very minor text and stat updates and corrections, I added a "referee's notes" page at the back, and I added some very cheesy black & white images in a few places.
Check out the links over there on the right for all the kobold slaughtering goodness!
If you are interested in a softcover print-on-demand version, it's available at Lulu here for under $3 ($4.99 in Canada).
On RPGNow/DriveThruRPG you can get the softcover POD here or here for $2.99 USD (which includes a free PDF). If you just want the PDF, it's free.
You can also download the PDF from Tabletop Library for free here.
