Hehe, zTex strikes back!? What would these deliver 400MH/s?
You may not believe it, but there is hardware which is not only developed for BTC mining. Screw drivers, for example.
Estimated hash rate of these FPGA's is indeed 350 to 400 MH/s
i Used kramble's litecoin bitstream on my ztex 1.15y's and one quad board puts out arround 60 kh/s.
