Modeled after the "Dead Poets Soci
ety," which was actually an appreciation group for classical
rhymesters, the Dead Com
puters Society is an appreciation group
for computer architectures that no
longer exist. It started as an informal discussion
panel at the 1991 ASPLOS ("Architecture Support for
Programming Languages and OS's") conference in Sa
nta Clara, California. A group of friends and
colleagues attending the conference noticed that many of them had worked on systems that were now
discontinued.
They decided to make light of this by forming the Dead Computers Society and holding an open
forum round table on the issues involved. The hope was that an intelligent retrospective would allow
future designers to learn from the lessons of the pa
st. Membership of the Dead Computers Society is
open to anyone who has helped design, build, or program a computer system that no longer exists,
ideally for a company that no longer exists. Ther
e are a lot of these; a partial list is shown in

On the other hand, membership is also open to anyone who just thinks it's a kind of neat idea. At the
inaugural meeting, there were over 350 attendees.
The panel moderator tried to draw the members out on the "one single thing that, more than anything
else, was responsible for your dead computer." The Elxsi designer said that they had tried to push the
technology too much and used ECL (emitter-coupled logic) before it was ready for prime time.
However, the chief architect from Multiflow, which went down the tubes around the same time as
Elxsi, felt that their decision not to use ECL was one of several factors that ultimately caused
Multiflow's demise!
About the only consensus was that management and market conditions were responsible for many,
many more bankruptcies than were technical failures. This is understandable; companies that don't
