You must have the following hardware and software in order to use GEOS:
• a Commodore 64 or 64C computer, or a Commodore 128 (running in 64 mode).
• a compatible monitor or TV. The best monitor to use is a Commodore 1702,1802,1902 or 1902A monitor. Televisions can be used, but the resolution is sharper with a Commodore monitor.
• an input device (joystick, mouse, Koala Pad, or Inkwell light pen).
• one 5 1/4 inch disk drive (1541 or 1571).
• GEOS package, which contains three program diskettes and this manual.
• blank 5 1/4 inch diskettes (for backup disks and work disks).
• The following optional equipment is recommended so that you can take full advantage of the power and versatility of GEOS. This equipment is not, however, necessary to the operation of GEOS.
• a RAM Expansion Unit (REU). With an REU the operating speed of GEOS is greatly increased. In addition, you will be able to dedicate more disk space to the GEOS program you are currently using.
• additional disk drives (1541,1571, or 1581). You can install two disk drives and a RAM Expansion Unit for use with GEOS.
• a GEOS supported printer.
