Mike McDonald - 17:59 07-07-08
I'm lokking for a small (4x6", 6x8", range) SBC that has a reasonably good A/D converter (100+MSPS),
at least one 1G ethernet, and one or more SATA-2 ports. I'm not picky about the processor. Anything that
runs Linux or an FPGA would be fine. A nice option would be an LCD and keypad interface.
