You run a repair shop on an alien planet. The locals bring in old human gadgets that broke down with age. They do not understand human tech, so they can only tell you what they saw.

Find the bug yourself and fix the firmware on the shop computer. Read the datasheets, edit the assembly, and flash the device. Then ring the bell. The customer tries the device. If it still fails, they hand it back and pay less for each failed try. After three failed tries, they take it home broken.

Earn enough to pay the rent. Buy new datasheets to take on more jobs.
