Re: Black Arrow 28nm 100Ghash Bitcoin ASIC from $1.99/GH/s, miners from $2.97/GH/s
I'll say it again:
Replace The Backplane with Wires
As in 1 (one) SPI channel PER HASHBOARD going direct to a controller. I hope to god you didn't have all the hashboards sharing a common bus on the backplane before - because I can't imagine trying to get that to work.
Dear Jonny,
The PCIE connector has 98 pins and there are 5 connectors in each case.
If you still believe that this can be done even on one X3 (not to talk about mass production) you are welcome to come to our office and try to do this yourself.
Regards!
that's like an apology, but different.
