Used TEMPEST
TEMPEST shielded computer equipment sometimes leaks out into the public in the form of surplus and
scrap sales. This section is devoted to descriptions.
One informant used to work at a Defense Reutilization and Marketing Office (DRMOs are the DoD's
version of a garage sale). In the past, TEMPEST equipment was de-miled (crushed), now due to
miscoding and classification downgrades, TEMPEST equipment is literally a dime a dozen. Computer
surplus goodies go for about 12 cents a pound.
Through a contractual association with a major defense company, Fluid Forming Technologies has been
assigned to dispose of a TEMPEST level "secured working environment." Modular construction, 160' x
20' x 10', can probably be segmented into smaller units. Available as of January 1, 1998. E-mail

JC describes two shielded IBM PC cases he picked up from a scrap dealer for $35 each (unfortunately
they had already sold the printers and monitors). The cases were labeled EMR XT SYSTEM UNIT (on
the front), with a model number of 4455 1 (on the back). The cases are similar to a standard IBM XT
case, except deeper toward the back, so a filter bank and power supply baffle could be installed. The top
is bolted down, requiring an allen wrench to remove. The top part of the case has a gasket groove for the
brass colored RF gasket, and the mating surface is a finished in anodized aluminum. The top appears to
be a cast aluminum plate. Each of the ports in the rear has a filter, unused ports have a metal blocking
cover that mates to the case and make a good eletrical contact.
W.J. Ford Surplus Enterprises(O) had the following printer for sale in December 1996:

As of February 8, 1997, Dark Tangent (of DEFCON fame) has a whole collection of TEMPEST
shielded equipment for sale. Check out his page (X) for complete info and photos. Lots of great details
and specs. Also a related Slashdot thread.
As of June 15, 1998, Hugh Sebra had fifty TEMPEST-shielded Fibercom 7197 DPT Dual Path
Fiberoptic Transceivers for sale.
While not for sale, H. Layer has a photo of a circa 1986 Tempest Macintosh as his cool Mind Museum
page.
Note: I personally don't own or have access to any surplus TEMPEST equipment. However, if you've
encountered such hardware, let me know about it.
Tales of the TEMPEST
Recent publicity about this page has resulted in some interesting personal accounts dealing with
TEMPEST-related topics. This section lists excerpts from various correspondence. In most cases, the
names have been removed to protect the innocent.

Interesting page of TEMPEST-related stuff. One additional information source you may
want to include for those attempting to proof themselves against an EME-type attack
might be the ARRL (Amateur Radio Relay League) Handbook for the Radio Amateur. It
has a very complete chapter on preventing radio interference caused by ham radio gear,
much of which could be adapted for use with a computer. The book is updated yearly, so
the information is usually top-notch. Most libraries have it.
BTW, for those on the other side of the question (or who wish to be) there's probably
enough info in the book to help them put together a TEMPEST monitoring outfit if they're
handy with a soldering iron.
