Specifications

for desktop presentations.

o  425SLC Premium -- active matrix color

The new DECpc 425 notebooks prove that you can have it all and take it
with you too. They give you the 486 power, sharp color, and
expandability of a desktop PC, all packaged to go.

Color and Power Plus
These two notebooks use Intel's new i486SL processor, a full- function 25
MHz i486 made just for notebooks. The SLC Premium features a dazzling
active matrix color display -- the best you can get for desktop
presentations. And both notebooks give you the functionality of a desktop
PC, with a removable hard disk, expandable memory, a docking connection,
and two PCMCIA slots for miniature option cards. The SL's monochrome
screen is even upgradable to active matrix color.

Notebook Mobility
All this power and upgradability come in a six-pound package designed to
travel, with a front-mounted trackball that's great in tight spaces.
Built-in power management gives you up to 6.5 hours between charges. And a
cable lock and two-level password protection keep your data secure.  With
these great features, a DECpc 486 notebook could become your one and only
PC. Its power and expandability make it as functional as any desktop PC.
But this 486 -- and its stunning color screen -- fit in your briefcase.
