get to post

To solve a problem at minimum. "Getting (it) to post" is the earliest point you can say "it works" without adding "technically," or the first thing that you have to do before starting anything else. Often implies that hard work and/or kludges were—and will be—required. Derived from the "POST screen" (Power On Self Test), where a computer checks if all its hardware is working after being turned on; the first milestone in building/fixing a computer is reaching this screen.
