NeXT 68040 configuration

I've added the NeXT slab schematics to SVN. I've been trying to figure out why the LOCK and LOCKE lines would need pullup resistors if they bus never goes tristate. I think that it may be due to the other NeXT chipsets. I currently have a huge slew of glue logic that I am trying to minimize.

The pullup lines from the NeXT are in the following illustration.

The SIZ lines and R/W does not have pullups, so the only thing that makes sense is that the NeXT proprietary chipset does cause the 68040 to tristate the lines. I will have to look into this, because SC1,0 are both to GND.
