- n. Same as test-box.
Sorry, no etymologies found.
When Garlock touched the knob of the testing-box he yanked his hand away before it had really made contact.
But excuse me, Captain Garlock, none of that is any of my business; which is to determine whether or not you four Tellurian human beings are compatible with, and thus acceptable to, our humanity of Hodell ... but you do not seem to have a standard televideo testing-box aboard. "
