That would be the LED for numlock. Just plug in any keyboard with a numpad to turn it off/on.
Ahaaa. Yes but of course. (Feeling stupid now). Haven't used a full size keyboard with numpad for a long time.
You can also turn off numlock from the on-screen keyboard in Windows 7/10

Cheers. I've already figured it out :-)
Here are some pictures of mine....
Using lubed 65g Zealios with my Retro SA set. At the moment I'm going all brown. Really wish I had gotten the PETSCII set as well, but didn't have the funds when the GB was running. :-( I'll experiment with different key color combination of the Retro SA set in the future. For now I like going all brown.
My first ANSI build and I have installed SE keys to get used to the layout (not good at touch typing).
I also have to apologize for the bad quality of the images. I used my phone and couldn't be bothered picking up my DSLR.
Really liking the layout and I am utilizing layers to control LEDs and Fn key for compensating for losing some keys to the layout and going from ISO SE to ANSI.
Unfortunately it is not all peaches. I have re-occurring problem with the Octagon that I've described here:
https://geekhack.org/index.php?topic=78549.msg2172587#msg2172587Edit:The issue seem to have mysteriously disappeared. Last time it happened I flashed it using Atmel Flip instead of O2D KeyMapper. It has been solid ever since. Been using the board everyday at work for a couple of days now. Hopefully I'm not jinxing it by writing this post and it stays functional.
