Hi, I am looking for a simple sample circuit (ideally with some sample code on the PC side as well) on how to extend a PC/104 bus (I understand it is just a 16bit ISA bus with different form factor). I googled for info on the ISA bus, DIY projects and the like, but I couldn't find anything that merges all the info in one simple circuit that I could extend with my requirements, which is basically implement a PIC24H on a PC/104 expansion card and interact with it using a couple of I/O ports addresses. I would appreciate any link anyone has handy.
