Default Re: MK14 schematic revisions

Well, since my eye is improving I thought I'd get back to sorting out the new PCB layout. I've managed to wire up all the connections on the edge connector to better match the VDU card (XOUT is on the bottom rather than the top, as discussed previously). I'm now trying to squeeze in an extra gate to fully decode the prom as this is going to make it possible to add extra RAM for VDU users and for some ideas I have. Here's a few screendumps of my progress so far.....

If there are any glaring omissions please feel free to point them out!
