I hope they don't go for to much perfection with the Neptunes... This still is an arms race and difficulty
rising exponentially is still a big part of mining. no..?
bottleneck with controller boards 
that's the simplest component of the whole miner. Could you
please explain Orama..? I'm not sure I'm believing this unless you/KNC can explain with more detail. KNC have
pulled miracles in the past with bigger volumes and now there's a bottleneck. I'm sure another PCB
manufacturers that can make it happen if existing manufacturer is busy.
Also. didn't KNC tell us to keep BTC handy for these Jupiters. What's changed..? Fear of Neptune refunds..?
by the way they sold out this shouldn't be the case.
Come on, we're all men here.. spill the beans even if some will get upset I'm sure we'll get over it.
I'm guessing the BBB (BeagleBoneBlack) could be a bottleneck.
Cointerra is using them too, and probably many others, because of the 'powerfulness' of a BBB compared to a raspberryPi.
BeagleBone is a US (non-profit)company/foundation, and rPi is from the UK:
Hopefully Cointerra (US company) didn't sign an exclusive deal with BBB, for a certain amount of time/products.
Years back Ipads were available and way too expensive for my budget. I watched closely for reviews of the tablets coming out of Asia. There was a write up on the Cortex A8 that sounded very good. Then Merrimobiles offered the Mid816 with the Cortex A8 at a reasonable price. I still use it as my goto tablet tho I have one newer and three e-readers. That Cortex A8 is the reason for choosing the BBB.
