ISA boards are still very available in the industrial market, and I think will be for many years. Cost is an issue there, however. Since you are looking to learn, it is a good entry level bus. Agreed, ISA is not exactly up to date technology. > USB bus easy to use but its packet stucture and therefore the latency is an > issue for some real-time applications. > > So, I want to learn how to build and work/play with PCI interfaces.

Someone else prove me wrong, but this is the lowest cost PCI proto board I've seen. $150 USD. But wait -- there's more -- it includes USB, too. It is CPLD based, so in theory you can use it for some other purposes as well.... not as many options available as with a full FPGA, but a good trade for the cost. http://www.altera.com/products/devkits/altera/kit-maxii-1270.html Thanks, Steve |
