Lol, I'm not heading to Wales anytime soon! :-)

Ok, it seems like there is a signal that Agnus is waiting for (and not getting) to continue the bootstrap. Anyone know the sequence for the ECS chipset?

-Edit- could Agnus be waiting for the chipram? Could that have failed?

A failed pull-up on that line somewhere, would manually pulling the signal high with a high resistance resistor cause any damage? Might be worth a go to see if that continues the boot?
