No one specified code, though that is a bigger problem. How muchIn article <MPG.23a706ae1955768d9896ec@news.individual.net>,

like that. It keeps things together.
Everything is formally released, archived, backed up. 10 years later,
we know exactly what was built when, and can build exact copies if we
need to.

Providing that you still have a computer that can read 5.25" disks.
Well, genius, most are smart enough to migrate their business
critical data to new systems when the old get replaced.
Migrating code for tools no longer manufactured/sold actually means
that the simpler and cost effective solution for some markets is
actually to archive complete computer systems as changing the tools
means revalidation/certification. Even if you could get the new versions
of tools to work with newer computers/operating systems/etc..
bigger depends on the tools (another vote for VHDL vs. schematic,
IMO).
If you're in a lifetime buy situation the tools don't matter,Especially if you have last time buy on components even at wafer
level because you are making parts for aircraft, classic examples
would be
however documentation still matters.
Why single them out?Boeing 747
C130 (Hercules in UK)
Nimrod (originally Comet airframe circa late 1950's)
Why is test equipment a problem?Having recently looked at some testing equipment that has to work for
at least 10 years, I am aware of the issues and multiple paper/CD/network
storage of documents etc..
