Acorn Archimedes A3010. Restoration complete.

Battery leak damage took out 10 tracks on the PCB including 5 that go under the floppy drive header and connect the pins to pull-up resistors.

I repaired the accessible tracks, rerouted the pull-up tracks and added a couple of wires at the old battery location so I, or the next owner, can put a battery holder in a sensible location and won't need to dismantle the entire machine if it's going to be stored for a long time. Floppy heads also cleaned.
