Black Arrow 6/15/14

We are happy to let you know that we've just solved the SPI issues on the X3. In the picture below we run only at 1.1Ghz instead of 1.2Ghz because we've hardcoded the voltage at 0.81V and 2 ASICs needed a little bit more. Our plan is to tape out the new backplane in 1-2 days, start shipping of X3 on 23rd (after we get the PCBs back and we assemble them). We should be able to deliver all X3s by the end of the month.

X1s:
We have confirmed that the first of our shipment of complete X1s without LCD will leave the factory late tomorrow for shipment to us. We will inspect and short-test these, and re-ship same day. We expect to start fulfilling first X1 orders then this Thursday/Friday, with the vast majority of orders being shipped out next week. We currently project having 70-80% of all B1 and B2 orders with appropriate compensation units to be shipped out by the end of next week.
