They have a history of reselling other peoples boards/chips but not of creating their own.
Can you explain using their boards in these?https://bitcointalksearch.org/topic/the-what-black-arrow-does-not-want-you-to-know-thread-313049

"I guess BitFury boards really are hard to keep running reliably."
Not sure what you want explaining but they are 3rd party 55nm BitFury chip boards, not their own 28nm Minion ASIC.
Hi Gator-hex,
I assisted in the launch of the BA Bullet Run and our co-op holds the rights to the exclusive Group Buy for x-3 Prospero GBs in February. They're not 3rd party boards - its a nearly complete test of the new BA Prospero design being launched in late February.
This allowed them to do a limited size test of their entire design and assembly process sans the Minion chip, while working with bobsag3 to troubleshoot problems and iron out issues (it also allowed our co-op members access to Bullet Run Prosperos 3-4 months ahead of the full launch).
The main difference is that this Bullet Run that's currently hashing uses 55nm Bitfury chips, while the February Prosperos will be using their own 28nm Minion ASIC. Everything I've seen/heard so far is that they still appear to be on track for a late February launch of their Minion Prosperos (in fact, absolutely no promises and don't hold this as holy gospel, but I understand that this is a conservative target date; as there's been too much over promising and underdelivery in this industry, as a whole).
