Hello, Has anyone had any luck downloading the spec. sheet for the new PIC with USB? I've downloaded it twice and both times Adobe Acrobat says it's corrupted. Has anyone tried this chip? I want to hook up an I/O board with 8 inputs and 8 relay outputs to a USB port on a Mac. I can't find such a beast so I thought I'd roll my own using the PIC. (If anyone knows where I can find a board with Mac drivers I'd be glad to hear about it) . Any advice?? Thanks! Jim
