Are there any developers or hardware manufacturers already committed to making boards or devices for these chips?
Burnin,
However he will probably order a whole batch of chips and sell the boards ready to hash incl. chips and everything else

Chip Distribution in DIY Volumes (50+)
About
Bitmine is offering Coincraft A1 chips in 500+ volumes to the masses, which for DIY folks might be unpractical. Therefore I am distributing some of the chips I ordered for personal use to the scene with non-profit intentions. Take this as a symbolic compensation for 2013's disaster the DIY scene was hit by. I am herein offering up to 5000 chips from the first chips in volumes in lots of 50 chips. The price is what Bitmine asks for the chips at time of order, with an 8% surcharge to cover S&H expenses.
Is this for me?
There was a great confusion with the initial announcement, so to clarify here: this offer is NOT for you if
How to order
I expect only a limited number of orders and will therefore follow a manual order processing.
Good Luck!
Initial Offer (for the records)
With the past BTC exchange rate movement this offer for buyers became not acceptable any more and is therefore halted.
Down-payments collected so far will be refunded in full.
A better offer will be available when chips are ready for distribution.
Folks and miners,
I am glad to announce that I have been selected by Bitmine as exclusive tier-1 chip distributor for the 28nm CoinCraft A1 mining ASIC. I will also provide the interface to the DIY scene and supply everything needed to enable community driven development and production of mining products as open source.
About
The CoinCraft A1 is Bitmine's first mining ASIC, which is rated at 20GHps at <0.6J/GH. It supports low-energy (down to 0.35J/GH) and high-power (up to 40GHps/chip) modes to allow optimal resource utilization during different stages of mining (please follow above link for more info). Throughout this offer, the rated specs are considered, i.e. one chip is worth 20GHps.
Bitmine offers bare chips to larger customers directly from their web-shop in minimum quantities of 500, while lower quantities are distributed by me in lots of 50 chips (or 1 THps). If you need smaller quantities, please organize a group buy yourselves to reach this minimum size.
I ordered chips from the pilot-run that is scheduled to be finalized by end of November - i.e. the earliest available chips. Those I am herein offering to DIY folks, which will be shipped out before December 13th (W50).
Chip specifications, design documents, reference software, and everything that is required to design mining rig development will be provided through github incrementally, with a guaranteed availability of all required support material by end of October.
Pricing
The price per chip is 8% above Bitmine's for lowest order quantity, which for December delivery is set to $5/GHps and corresponds to $108/chip. I am operating only in the BTC domain and set the price using BitPay's exchange rates. With today's rate, the price is 42.5BTC per 50-chip lot (1 THps).
Shipping
I will receive chips in W49 (first December week) and will distribute them no later than December 13th.
Priority shipping is included. Urgent / express is available on request for an additional 1 BTC.
Bitmine provides a Customer Protection Plan (CPP), which fully applies for the chips offered here. The agreed shipping date to be considered for that plan is December 13th.
Availability
I have 100 lots available (5000 chips). Chips are distributed in the order down-payment is paid (see below).
Availability ends October 19th.
Edit: Chips will be available at least until their delivery date. A final notification will be made prior to closing the order window.
How to order
Since the number of potential buyers is limited, the orders will be processed manually as follows:
1) Place your buy order via email
2) If not sold out, I'll provide you with a payment address
3) You pay 20% down-payment, which is only refundable if I fail to deliver in time (see CPP)
4) You pay the remainder right before chips are shipped
Addendum (2013-09-17):
Sample Chips
The chips offered here are from the pilot-run and are exactly meant to be sample-chips, i.e. they are the first available ones. Obviously ordering a full lot of 50 chips only to test board designs is a barrier for DIY hobbyists. Therefore the following special conditions to support the DIY scene are added:
1) chips for design verification can be ordered in smaller quantities (1-31 chips, 0.85 BTC / chip)
2) an additional low-quantity fee of 1 BTC per order is charged to make up for S&H expenses
3) down-payment is at least 1 BTC
4) all other rules stated above for lot orders apply
Cheers,
zefir

Is this for me?
There was a great confusion with the initial announcement, so to clarify here: this offer is NOT for you if
- you need more than 500 chips
=> order at Bitmine and you will save the 8% surcharge and even get discounts on higher volumes - you want a manufacturer to build your board(s)
=> order your boards at the manufacturer of your choice, he will get better prices with higher volumes - you want to organize a group buy
=> please organize your group buy so that you can make a 500+ order at Bitmine directly; I do this at no cost to support the open source DIY scene and don't want to run into multi-party deals and related troubles
How to order
I expect only a limited number of orders and will therefore follow a manual order processing.
- orders are placed via email to this address (please leave the Gmail alias suffix intact)
- with the order, please include your shipping address (if possible with phone number for express); if you are concerned about your privacy, please use PGP encryption (my public key is in my sig)
- chips are offered at Bitmine's price for 500+ chips at time of order +8% (today 3.5$/GHps, including surplus: $4'725 / 50 chips)
- you will be asked for payment once I know chips are on their way to Switzerland
- payments will be in BTC only and based on BitStamp exchange rate at time of payment
- should I fail to ship your chips within 2 weeks after your payment, you will be refunded the exact amount of BTC you paid
- orders are processed FCFS, no pre-order, no down-payment
- buyer is in charge for taxes and customs
Good Luck!
