I'm enjoying this meticulously crafted game, thanks for writing it. I had some trouble working out how to use the temporal relocator - even though I had already fixed the circuit board, inserted it, and obtained the device. It wasn't clear to me that I had to 'Use Temporal Relocator.' I think this was because if you type 'x temporal relocator' you get the response "You can't see a machine here" (or something similar). So it seemed to me that you couldn't interact with the TR. I thought you probably had to carry on fixing the machine or somehow find a code to put in the keypad. (I only went back and tried again because you talked about a menu for using the machine in another comment, and you said that after sorting the circuit board you can time travel.) By the way, 'Use Machine' should probably work as well.
