bitaxeUltra release coming soon!
This fully open source #bitcoin miner has a single BM1366 ASIC (from the S19XP). It runs quiet and cool at just about 500 GH/s
on July 03, 2012, in a BitcoinTalk discussion about the first ever mining ASIC;
"I would personally love to see a well documented Bitcoin-specific ASIC that is sold by reel (or in smaller quantities to hobbyists by a retailer). This way there could be many companies developing and offering products from "coffee-warmers" to 4U Terahash-class racks."

I have been head down lately on day job work, but this #bitaxe ultra has been hashing away, cool and quiet amongst this snow drift of boards on the back corner of my desk.
Right around 500 billion hashes a second, every second of every day.
> Most miners will precompute the SHA256 "midstate" from the first 512-bit (64 byte) chunk of data, and only repeat the 2nd SHA256 round with the final 512-bit chunk (which contains the nonce).
