Jupiterium This is an Educational Game Mactivity's CD-ROM nr 10 advice: This application did run on a b/w 68030 processor under System 7.1, but the behaviour on a ColorScreen of a PowerMacintosh running System 7.1.2 was not satisfying. Our advice: use only on 68030 processors, or try with caution on a 68040 processor Jupiterium creates a simulation of Jupiter and its Galilean satellites as viewed from Earth through a small telescope. On-screen dimensions are accurate to the nearest pixel, and positions of the moons are accurate to a minute or two of time. [In the present form of this program, actual eclipses of the moons (i.e., by Jupiter's shadow) are not shown, only approximated by occultations (by the planet's disk).] Transits are distinguished from occultations in that a moon is shown in contrast against Jupiter's disk when in transit and not shown when occulted. "Jupiterium" is for Macs without a floating-point coprocessor (6888x chip) and "Jupiterium881" is for those with. You'll first be prompted for information related to your time zone and to choose whether the view should be set to correspond to that produced by an inverting, a reversing, or a terrestrial (spotting) telescope.
