The Olympus m:robe MR-100. You have no idea how difficult it was to get this shot with all of the machine's lights on at once.

Second photo shows you the tools you will need:

Your standard small philips screwdriver.

A tiny philips (about a step up from an eyeglass screwdriver, although one of those might work aswell).

A couple of Spudgers or plastic opening tools. As you can see, I used Guitar pics, which work pretty well. I suggest thin metal or some cheap plastic ones that you don't mind breaking.

I'm sorry I don't know the actual sizes of the screwdrivers, but if you use the guitar pics as a reference (they're about the size of a quarter) you should be able to estimate it.
