Investigate some old prototype hardware your Aunt found in the attic. She's sent you some of your Uncle's old machines before, but this is primitive in comparison and clearly partially handmade. There are also some documents that just don't seem like your Uncle should have had casually stashed in the attic. What was he up to? What was his involvement before the TESS project that produced the TIS-100 machine? Debugging that machine changed your entire world. What now?
