Hi Don, I have SMB boards available. $20. You'll need a display mezzanine for it. There are three different ones depending upon your displays (TIL311 - $6, LED Bar - $10, and HP5082 - $10)
Shipping is $5.95 in the US. Thanks, Todd * Don Caprio <[email protected]> [140610 14:42]: > I don't have a SMB board. Any available?
