===============================================================================

KEY FEATURES:

 * 105 Million Byte capacity           * Mobile, removable & portable
 * Superior performance under          * Shock sensor protection - 
   rugged environmental conditions       up to 100 Gs - against overwrites
 * Cardlock TM access security         * Automatic head lock and unlock


 The MobileMAX 105 is a 1.8-inch disk drive with the highest capacity of
 any PCMCIA-compatible drive currently available.

 About the size of a credit card, this removable drive weighs 2.5 ounces
 and measures 10.5mm high. The MobileMAX 105 MB drive is ideal for use in
 notebook, sub-notebook, handheld, and desktop computers equipped with 
 PCMCIA Type III compatible interface card slots.

 Able to withstand 300 Gs of non-operating shock, this drive allows users
 to move large volumes of data between mobile and desktop systems - easily
 and safely.

 The versatile MobileMAX 105MB hard drive meets the capacity and 
 performance of Pen-based systems as well as DOS and Windows environments.
