We're trying to make our own system that doesn't end up being any larger than a competitor's system. Their system is housed in a metal box about 4(W) x 2(H) x 6.5(L). They are using embedded Linux on an ARM processor with a DSP (SHARC ?) to handle the I/O. I was pointed at Advantech: http://www.advantech.com/products/Model.asp?Category_ID=1-D6LKEbu= and have found similar PC/104 equipment at a few other vendors. Without doing much research (we usually build much larger VME based systems), there seems to be a lot of options in PC/104 modules. -- Dan Eischen ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]
