  • "Sol's Neighbors" (81k) - A star catalog with 3-D mapping graphics and properties of hypothetical Earth-like planets for all the star systems within 16 light years of our Solar System. Recommended for SF writers who are planning "a little trip".

  • "The Chemical Elements" (106k) - A periodic table of the elements with chemical properties, some isotope data, and electron shell structure diagrams. This stack is intended for operation in conjunction with the Isotopes stack (below).

  • "Table of the Isotopes" (455k) - An isotope table compiled from data downloaded from a DOE database in 1987, including capabilities for transitions through radioactive decays and nuclear reactions. This stack is intended for operation in conjunction with the Chemical Elements stack (above).

  • Stack Trio (607k) - Download all three of these stacks at once.
