As from now I'm the new owner of this beauty

Didn't had time to do some proper testing, in the weekend I'll fire up my SUN Ultra 5 station and make some real life tests.
I have typed on all kind of SUN keyboards, and must say that this one is by far the best one, the black switches have a nice feeling, they're not scratchy at all. For a 60% user like me, this board is huge, but is a Cherry MX SUN compatible board, and that, for a long time SUN fan is a great find

One weird thing I noticed are the stabs,they're like noting I've seen before. These are kind of Costar-ish type, but compatible with nothing, I'll take some photos because these I really something than can not be described in words. Even the spacebar is non standard, the mount points are in the same place as for 6.25u but this is a 7u spacebar.
Maybe I will try also a Teensy conversion for this board, looking over Hassu's code I discovered that you can use it without any additional circuitry.
A guy already done this conversion, and also made some changes to the code
