I've started laying out the back plane -
I am having some issues. The backplane is bigger than a A4 sheet of paper so I have been cutting the width of it back. It is still printing out of proportion and I don't know why. What should be 11 inches is coming out as 10.9 inches on paper.
After this issue occurred I went and checked my etching bowl and it's too small as well :(
The connectors arrived, 5 of each. Enough to get started.
The layout is like this -
Power
8 signals

I'd use more ground and power traces but it's hard because you use only 64 of the 96 pins.
Seriously, if you can etch that by hand, you're a genius. I'd rather chase a used backplane on eBay...
Are you sure? yes | no
