Got it to 99.9% now :) but as you say its still taking chunks out of the GND layer
I turned off GND & VCC layers, its on optimise 1 currently..

But looks like it did what V7 did and route the signals already routed :roll:

I think Eagle router just doesn't do what I want it to do :(

2.5 hours and it finished routing. So its twice as fast as the V7 router easily. Though it doesn't help when it crashes, so its unusable anyway. I half think I could have routed the whole thing manually by now :roll:

What I can either do is try and fix the one where it trashed the ground plane, or do some more routing manually and then try the autorouter again :roll:

One thing I have been wondering, is moving the bus pull up resistors to the 68K expansion socket area as opposed to the CPU area...

Basically because the two resistor packs to the right of the CPU squashing up a lot of tracks, so it may ease the routing if they were moved elsewhere...

I wanted to keep the pull-up resistors close to the CPU, though with this board aiming towards a CPU expansion board, the pull-up resistors would probably be better close towards the expansion sockets anyway...

See what you mean, with them next to the CPU makes for a very congested area.

Besides we can always budge more pullups on if necessary.
If it ain't broke, test it to Destruction.

Yeah, I'm sure there will be some resistors to bodge on somewhere :)

Started moving the SILs...

While I am messing about, I started to get rid of some of the angles in the buses between the 68K sockets.. get rid of those nasty angles a bit..

Careful. You will end up routing the whole board by hand :)

Yeah, it seems to be going that way anyway :roll:

resistor packs moved, and expansion sockets re-tracked..

I was half thinking of just leaving this resistor pack there, but I think in terms of consistency, I will move it near the other ones I have just moved as well.

and we off...

I can see at the top ( marked with white arrows) there was a lot of buyers simply because of one trace, if the optimisations don't solve it, I will do a little bit of routing of that part manually on the VCC layer and hopefully that part will get a little neater then...

Is it me, or does this look super nice in blue ?

So after a epic 12hours , it finally routed without trashing the gnd layer :D so moving those resistor packs has given it a bit more room for routing. So next I will see where the bottlenecks are on the routing to see if I can improve on it.
