The equipment that Meta/Maine used were mostly hardware items. While the software that operated them was erased it would be simple to re-install that data. The EMP doesn't effect hardware.

Church/Alpha, Tex/Beta, Delta, Omega, Sigma, Iota, Theta, and Sigma (I think I got all the ones present at the EMP) were completely SOFTWARE. 100% data. The EMP wiped them out, scrambled beyond recovery. No backups from which to restore them (like the systems that run a PC or the Freelancer equipment) because it's stated that since AI are based on a human mind (and going by Halo mythos use advanced bio-tech of some kind to be created in the first place) copying them is impossible, hence the existence of Delta and the others.
