Finally, I've been able to finalise the design of the second version of the ZAViouR Board, along with a 7400 based I/O board that plugs into the ZAViour's expansion port. The designs have been submitted to my favorite fabricator www.hackvana.com and I'm awaiting news of their acceptance.
I have added a few new images to the gallery and removed some of the old ones. The schematic is just as a rough guide, as all of the design files will be available on my website www.projectavr.com as soon as I've tested the new boards.
I've also been working on other I/O board variants and the backplane which I will have fabricated later.
