Here are the answers which were released with the game. At the time the game was released, numerous answers were found to be wrong. Since then, others may have become wrong. As was mentioned to me by an RT enthusiast, figuring out which answers were wrong when published is a second-level trivia game. I would say that figuring out which ones are wrong NOW would have to qualify as a third-level trivia game.

Additional questions:

• Q: What is the difference between the designations PDP and LSI
• A: PDP is a system-level product, LSI is a board-level product

Corrections and/or explanations for selected original answers:

• 0-0-1 The GT40 was actually a PDP-11/05 with a specialized backplane designed to accept the three boards of the VT11 graphics display processor. It was typically configured with a second serial line and the motif was mustard/brown.
• 7-0-5: Should simply be "RT = Real-time"
• 7-2-1: Should also list PDP-11/03, since the WCS option provided a writeable control store
• 8-0-1: EAE = Extended Arithmetic Element
• 9-2-2: List Processing language
