DRS - LXI
Full-size military laptop

The LXI is a rugged PC built around 2000 by DRS technologies in the UK. The PC is housed in a very sturdy case and has many provisions to make it TEMPEST safe. It has a built-in laptop-style LCD screen, a detachable keyboard and a series of peripheral connections at the rear.
 
The DRS LXI runs on Windows and has a built-in harddisc. The sturdy keyboard can be removed from the laptop and placed on the table. To the right of the keys is a built-in tracker ball which is used as a mouse. Additional mouse buttons are placed around the tracker ball.

At the front of the PC, behind a TEMPEST door, is a removable 3.5" harddisc. At the right is another door that gives access to 2 PCMCIA expansion slots.

All connections are at the rear. It has a standard 15-way VGA socket for the connection of an optional external monitor. It also has two 9-way RS-232 ports (COM1 and COM2) and a 25-way printer port. The latter is used for the supplied ink jet printer. Storage capacity can be extended by connecting an external SCSI device. The DRS LXI has a built-in modem and can be connected directly to an analog telephone line. Furthermore, there are connections for ethernet (NET) and the Belgium BAMS combat net radio system.

The LXI was later followed by improved versions such as the LXI-3 that was released in 2003. Apart from the common improvements in performance, drive capacity, etc., it is nearly identical to the standard LXI. DRS also produced TEMPEST PCs and is still in business today (2011).

Storage case
Although the rugged case of the DRS laptop is perfectly suitable for storing the machine, it was usually packed inside a large air-tight fiber storage container. The computer and the accompanying printer are stored inside the container in such a way that they can be operated without removing them.

Other cables can be stored under the laptop or inside a special compartment inside the top lid of the container.

For transport by air freight, the pressure of the air inside the container can be balanced with a small vent at the front.
