Right now I have:
1 Red
3 Blue
2 White
2 Black
2 Purple
I also have parts for more (besides blue) if needed. They're flashed to XeniumOS MakeMHz 2.3.5, have all been tested to boot to a BIOS, and come with 2x7 pin headers. I also have LPC rebuild boards for 1.6 consoles if you need that.
OpenXenium: $35 + shipping
The LPC board is an additional $2
Ships from the USA, send a PM if you're interested.
