Thanks, tips.

its unfortunate some people are fairly ignorant of scams, bitcoin users are frequently hit by them.
It simple, I sell
Still looks like a scam to me, lying about custom chips, lying about delivery, lying about availability, possibly using 2nd hand parts.
The BFL company is like a rotting sheep carcass in the sun, the more time goes by the more it stinks.

You really need to take a second, dust off that brain of yours and start using it before you post.
Definition of scam: a confidence game or other fraudulent scheme, especially for making a quick profit; swindle.
They've been selling their unit for months now and are still shipping product every day. This is the de facto antithesis of scam. I'm not going to waste my time re-iterating the invalidity of your claims (aside from shipping since you're correct). It's never not going to look like a scam to you, that much is obvious so quit trolling BFL threads with your useless rhetoric. They use EOL chips, SURPRISE. This isn't some brilliant new discovery for you to now harp on about.
I generally pride myself in being a tolerant person, but for once I'm going to have to swallow it (my pride). Welcome to my ignore list.
...BFL singles have so long waiting times - BFL can't buy enough FPGA's.
Bingo! Mystery solved!!! Now BFL is not a SCAM, not a CON, just lack of production supplies.
How ridiculous can a human look, when he is so jealous, that he can not afford himself to accept a simple fact...
Well he is least guilty of shady business tactics.
If he played by the rules he would have come forward straight ahead with the real, not inflated specs, the fact that there will be a limited supply and what hardware he is gonna be using. I would have bought one if I knew what I get.
Instead he decided to claim he is using a custom chip and stated the product will have 120% the performance and 60% the power requirements it actually turned out to be.
Lots of people are feeling the same way.
He fucked up, he could have secured himself a cutting edge position in the market with a innovative idea. Now BFL will probably end up as a side note alas:
'First closed source mining implementation using discount pro-grade fpgas'
And BTW: This could very well still turn out to be a scam.
What do you think will happen if there aren't enough EP3SL150 available for cheap to actually build the rig boxes people ordered?

ngzhang, can you probe the device to see if anything at all has been loaded into the firmware? its still a possibility that there is a very good reason someone already has a "broken" bfl single, that is to say they may all be "broken," ie no firmware.

sorry, i just returned the box to the owner....
Also, did the box have a return address label from Kansas City, Missouri?

LOL about the post above 
Anyway - the most important part about this thread for people WITH a BFL is the obvious:
Anyone got a bitstream that they can modify to run on the chip and we can then start making these things perform better?
(and of course the software to update the bitstream)
Since, of course, I'd be more than willing to update the BFL support in cgminer to support a better bitstream

What I really do think is, that BFL use new chips in their products, that they are improving their products and they are far more competitive than any other FPGA mining hardware developer today. It is just a speculation, that they use used chips in their products, just to rationalize a silly MH per $ of an own product.
The fact is, that guys from BFL are the only players on this field, who put some real money in their business and they start to dominate in mining hardware market. I am more than sure, that they will use improved chips in their newer products and they will offer something even better in the near future.
I have made this conclusion from reading almost 200 pages half off-topic threads about BFL...
Hopefully I managed to answer adequately to your question.
I am pretty sure they are using different chips for the boxes.
Thanks for confirming, ngzhang. It is not too surprising of a discovery, as the Stratix III EP3SL150 was one of xaxik's reverse engineering guesses: https://bitcointalksearch.org/topic/m.720365
The most surprising, for me, is to learn that used units of these FPGAs sell for $50-60 in China. Two chips per Singles, plus $50-80 for the remaining components, means that the BOM cost for a BFL Single (with used FPGAs) is ~$150-200. This means anyone with a chinese source of used FPGAs could manufacture BFL Single clones producing about 5 Mh/s per dollar(!), making it by far the most economical mining platform.

Will someone be able to produce free software for it ?
The nice thing about VHDL / Verilog is that it can be compiled for every FPGA.
Optimizations for the specific device can be done so it probably wouldn't get BFLs performance initially but would most likely surpass it considering how many more people are involved.
Well at least I got a meaningful update to my FIT data question. Not that any FPGA would be the weak point in those calcs anyway...
Designing an 80watt board is not as easy as designing a 40watt (8watt per chip) board. And obviously whoever designs it will be interested on making a decent profit on it. So maybe it won't be less than $500 USD.
Nice job!

i'm no expert but i think they use different chips.
Either you are wrong or ngzhang is lying.Ah, yes that could be the case.
But since BFL hasn't come forward with any information either that is pure speculation.
