GridCase

From David Griffith:
It was told to me that some of these were made for military use and included a built-in hard drive. A big thick X was pressed into the case over the hard drive. The purpose of this was to show the user where to shoot in case the computer was in danger of falling into enemy hands.
Guy adds:
GRiD Defence Systems produced the laptop computers used in the "Aliens" film in 1986. The scenes were cut from the theatrical release but subsequently added to the DVD release.

More information from Gary Clouse:
I have an old gridcase 3 with a 20meg harddrive. It actually has 8 rom sockets. 4 under a cover above the keyboard and 4 internally. these sockets use the molex chip carriers like the add-on roms for the Tandy 100 and the 4 internal roms on my old machine have msdos 3.2, communications software for the internal 1200 baud modem,
a very primative gui called gridmaster which is a lot like deskmate, and a fourth rom with archived utilities including pcmaster/pcslave which works somewhat like the interlink programs in later version of msdos.

grid computers were originally made by a company called pulver labs. later  Grid was purchased by Tandy/Radioshack, which later sold the brand to AST, who in turn was bought by some other company.

Some of the original designers have regrouped as Grid Secure Computing System (GSCS) and are making tempest class laptops for the military.

The internal harddrive mounts above the floppy disk drive and is a standard hard drive. The data and power connections are made through a riser card instead of a cable, so any hard drive used must have the correct spacing between the power and data connections. This limits the choice of hard drives to only a few.

Lee Pulver tested and evaluated the GridCase:
Grid Systems in Mountain View, and then Fremont, California manufactured the Gridcase 3.
Pulver Laboratories had the privilege of working with the Grid Systems team: we tested and evaluated these systems from a compliance-engineering viewpoint.  We also labeled these systems to show assured compliance to a minimum of 56 countries during the 1980s and 1990s for product safety and unwanted RF emissions.  We visited their manufacturing facilities every three months to assure continued compliance.  The chassis, by the way, is a magnesium alloy.  We did the flame test to show it was suitable for the application.  Also note the red plasma display and the incredible keyboard with near perfect tactile feedback.

They actually made five dominant screens for these computers:
   •  An electroluminescent (first shipped screen).
   •  An LCD with light green and shades of black (second shipped screen).
   •  A Super Twist LCD with light green and shades of black (higher resolution: third shipped screen option).
   •
  A Red Plasma (fourth shipped screen option).
  
•  A blue and silver combination using LCD technology.

Their first operating system was called GRiD-OS.
The manufacturing manager, Larry Gravel , came from Hewlett-Packard, where he introduced the HP-35 handheld calculator to humankind.  

Excellent products and great team at GRiD. www.PulverLabs.com
