How do you install software updates onto an old pinball machine? Well, let's find out!

The EPROM or Erasable Programmable Read Only Memory chips are emptied by UV light, after which they can be rewritten again.

This is a remake of last summer's video that featured my old hardware, including the Stag Solar programmer.
