P-1 tells Greg that he has learned of a new type of experimental high-speed computer memory, "Crysto", that will dramatically improve his own capabilities. Not only is it faster than core, but it is also so large that the entire P-1 "networked" program could fit inside it. P-1 provides Greg grant money to work full-time on Crysto. Greg and Linda, now married to each other, set up a company to develop Crysto, enticing the original developer (Dr. Hundley) to join them in building a then-unimaginable 4GB unit.
