  Oh, for Pete's sake, a Tempest terminal, right
when we're talking about 
 classified info.  Just so you know, this one is compromised by the 
 insecure monitor (I think - it should be MUCH bigger, and not plastic, 
 if Tempest approved) and the non-Tempest keyboard.  "Tank-like" is a 
 very concise description. 
The Tempest 5150 (or whatever the Tempest designation was for the IBM 
XT) that I have looks like a regular B&W monitor. When I took off the 
cover, the shielding became apparent :).

It has been quite a few years since I looked at it, but I believe the 
Tempest IBM XT I have is complete including Tempest keyboard and monitor.
