So I got another package in the mail today, and this little guy was inside!

This was a purchase from the local eBay branch Tradera, and as you can see it suffers from a damaged display connection. Other than that, it seems to boot just fine.

-'But RasmusB, you already bought an Ericsson MC218, and that one even works! Why did you buy this piece of junk?'

The answer is simple - I live in Sweden, and I want to be able to type Swedish characters on my handheld. This unit has the Scandinavian layout, as can be seen here:

The Å, Ä and Ö keys are the important ones if you are writing Swedish. The other two characters (Æ, Ø) are not used in Swedish, but since they're on the keyboard I'll probably implement them as well. I'll make my USB keyboard controller work with both the English and Scandinavian layout so it's useful to non-scandinavians as well.

So now I'm just waiting for my breakout PCBs so I can start hacking on these keyboards (pun not intended).
