Most problems with SkyGlobe 2.5 can be solved with a careful reading of the documentation, contained in the file SKYGLOBE.DOC. To print this file, use the DOS command COPY SKYGLOBE.DOC PRN. You can also import it as ASCII text into any word processor, but you might have to reset your margins. If you have a laser printer, you will have to change the type of printer from dot-matrix to laser. Use 'Alt-Shift-P' to do this, and use 'F2' to watch what you are doing. More detailed instructions are in the documentation. Because of the low resolution of the multi-color modes of the CGA graphics adapter, the CGA display is in black and white. The 16-color mode offered by some Tandy computers is not supported by SkyGlobe 2.5. If you are unsure if your computer has EGA or VGA graphics, nothing bad will happen if you try them. If your computer doesn't support the video choice you make, there will be no star display, but you should be able return to DOS by pressing 'Q'. If the planets are not displayed, make sure the appropriate .DAT file for the year you are viewing is in the same directory as SKYGLOBE.COM. If you have removed the floppy disk, replace it and press Enter to reload the planet data. Daylight Saving Time causes a few problems. SkyGlobe assumes that April 4 is the first day of Daylight Time, and October 27 is the last. (Northern Hemi- sphere) This approximates the current US policy of first Sunday in April, last Sunday in Oct., but will still be off by a day or two most years. You can use 'V' to shut it off, but there is no way to force Daylight Time. If the display jumps unexpectedly in Auto mode, Daylight Saving Time is usually the reason. Finally, Real-Time mode will keep you from changing the Time and Date.
