The design side is easy for our very able team. To give you an idea the design, and first proto was built, of Merrick1 in 8 weeks. That's 100X the complexity of what we are doing on this first Bitcoin product. I could give a very long list of similar examples of other projects. This is a professional design and manufacture team that's at the top of profession teams.

We will look at FPGA optimisations and software aspects but I won't promise any timelines. That's part of the reason for the current price. You will have to do a bit of work yourself so this may not be for everyone in this raw form. The timelines on this will depend on what else the design team end up doing. The team is rarely underloaded so this sort thing can take time.

yohan,

some rough edges are not a problem as long as the board has its FPGA bitstream and there is a description of the protocol used to communicate with onboard FPGAs so that mining programs can be upgraded to use your boards.

if, on the other  hand, you're selling a "naked" board, without any software nor FPGA bitstream, then this should be clearly stated since very few here will be able to use them even adding a lot of work Smiley

spiccioli.

This isn't a PCIe board. We may do one more specific PCIe board for Bitcoin and better price than the Merrick6 option currently available. I won't promise this at the moment but anyone has a serious interest, i.e. some numbers, do come and talk to us.

We have stock of the XC6SLX150 at our Xilinx distributor on normal call off that would cover maybe 500 boards. It's a part we already use in reasonable numbers on other things. That is why we can do these timescales. After that silicon is currently on about 6 weeks lead and a manufactured board would have been about 10 weeks.

Finally some tough competition against the BFL Single!

This $640 quad LX150 board would have about the same perf/dollar as the Single (1.33 vs. 1.39 Mh/s/$), but should have twice the Mh/Joule efficiency!
And if you, Enterpoint, can truly deliver first prototypes by the end of May, you would beat the (currently) 10-week waiting period for Single orders.

* mrb preorders...

yohan,

this is not a pci-e board is it?

Are you going to develop mining software or use an existing one, like

mpbm  https://bitcointalksearch.org/topic/modular-python-bitcoin-miner-official-thread-62823

or

cgminer  https://bitcointalksearch.org/topic/old-bfgminer-modular-fpgagpu-gbt-stratum-rpc-avalonlnxopnwrtppaw64-78192

And, while we are at it, please consider, while developing your FPGA bitstream, the p2pool issue, that is FPGA should be able to report a valid hash as soon as it finds it and be able to be interrupted before exhausting the full nonce range.

spiccioli.
