Story related, can’t miss. Chapter 3 after “A Spectral Presence” and yet again an easy set. Back in the Lab, examine the work counter and read the letter and book. Click the motor to connect the machine, then set No.0 to 99, leave 1-26 as they are, and 27-39 as 0. Then click the red button on the machine and click the letter reels until “IM” appears. A slight bug here means you may have to click the motor or come out of the work bench and go back in again. Achievement will pop when you examine the reels after “IM” appears.
