Wow, cool you put the minimig in a keyboard. Nice Job!!! I need a "Retro Desk" I was thinking of a setup like that today.
I have been using my c-one as just a raw board, one of its downsides is the fact that it is bigger than mini-atx (3 Slot), but smaller than full atx (5 Slot). Its like a 4 slot board... I refuse to put it in a mini-tower. I have yet to find the perfect case for it.
Pretty soon I'll make one on my own if someone else doesn't do it. Maybe Loriano actually has something in mind here? I'd buy one if it was done as nicely as his other case.
It's probably best to keep the non-minimig discussion to the alternate cores section. Why don't you create a thread in there. I like the topic.
The Minimig is a real botch job. It's a plain old eMachines keyboard I had going spare, I then used a Dremel to cut out the area needed to fit it, added a couple of rubber feet at the front to raise it for the PIC, shortened the keyboard cable and ran it around the keyboard back to the Minimig... and that's it. Took about 45 minutes.
Changing the SD card just means flipping it over. Here's the underside (same type of keyboard shown before and after):
I'll do as you suggest with the alternative cores. I'm hoping that the C-One shows up soon.
