Okay, your SSA boards need to host what, 10 drives?
tx+, tx-, rx+, rx-, 8 ID pins, what, 8 power pins? 2 for activity LED, what
else? that looks like about 20 per connector + discrete components, maybe
40+ the interconnects to whatever the backplane boards connect to?
Okay, maybe 300 per board at the most... I've done more wire-wrap than that
on one board...
I don't think it'll be that difficult. all I need is the physical layout
parameters for the board and time to lay out the traces so that they're all
the right length (signal) or width (power).
