Memory can be increased by purchasing a memory card which fits into the PC Card slot. This slot holds a single Type II PC card and follows the ATA standard. Although Type II cards are standard, the formatting on them is not. Other brand Type II PC Cards cannot be used in GeoBook. But, Brother PC Cards can be used in some other devices.
Flash memory is simply non-volatile storage memory.
No back up power or battery is required to maintain the information written or saved to this memory. GeoBook has 1 MB flash memory on the main board and it is used just like a hard drive. After creating a document, you will designate where to store the file. Files can be stored on the floppy, on the internal flash memory or an optional PC card. At this time GeoBook has no driver to support the ZIP drive format and none is planned at this time.
