Retrieve the Economy Disk and deliver it to McClure in Vault City

Retrieve the Economy Disk and deliver it to McClure in Vault City is a side quest in Fallout 2.

Walkthrough
After finishing Optimize the powerplant, go speak with Gordon in Gecko junkyard. He will tell you that after the powerplant is optimized Gecko can sell excess electricity to Vault City for medical services, and ask you to deliver some economy data to McClure in the Vault City in hope of making an agreement.

Note
The quest can be started even before repairing the powerplant, but the economy data cannot be given to McClure for the reward until after the powerplant is optimized.
