There are a couple of videos of the KENBAK-uino at the end of my flickr set, KENBAK-uino | Flickr
The first one shows me entering a simple program on the front panel, the second shows the sample programs I include in the sketch.
The only youtube video I've found of the original is this World's First Personal Computer - Kenbak-1 Taken Apart and Shown by Pioneer Robert Nielsen - YouTube.
Here in New Zealand, I used these buttons http://www.jaycar.co.nz/productView.asp?ID=SP0603 and this case http://www.jaycar.co.nz/productView.asp?ID=HB5970. I've attached a PDF of the faceplate and drilling guide.
