p.s. these computers mentioned in a previous post also have video cards
that support both VGA and RGB monitor graphics.

Cord:
My experience with these "TEMPEST" machines is that it's usually best to
swap out all the parts (great difficulty at times) and use the AT parts
in another box. The box is heavy and, as you stated, designed to
firewall the parts from the actual physical ports. There are good parts
on them however, disk drives, scsi connectors, video cards, mother
boards, memboards, that would work nice in another box and be easier
(read that cheaper) to mail.
What's the total weight in case I want one? Any ideas?
Do you have the color monitors?

Isn't the idea of TEMPEST to shield RF so nobody can snoop your data? I
would think the monitor itself would have to be an integrated part of that
contraption (which I suppose is why GRiD laptops made popular TEMPEST
machines).
I also thought that you needed a license to use TEMPEST equipment (I
suppose based on the same logic used to support the Clipper encyption
chip: the gov't wants to be able to snoop your compute sessions). If
that's the case, you should get the whole machine instead of just the
parts :-)

"TEMPEST" standards are there to afford proper sheilding to prevent
radiations/emmisions fromt he machine when it's being used for security
information. The thicker covers, ground braids and multiple screws in the
covers make it better sealed and there should be no emmisions over 12 inches
from the machine, or none at all ideally. Other than
the power supply being a
class A type, the rest is normal but may have been refitted
with a shielded
faceplate.
