 That's
why we should do it now, not later ;-)
 
Huh?  DEC service and software listings on Diazo?  Hmmm, you
are right!  I always thought these were silver film, but
just took a look and they are very dark blue Diazo.  On the
other hand, these are VMS 4.2 fiche, so QUITE old, and look
totally brand-new.  So, we have a few years yet to find a
way to read them.
I am familiar with that frosty Diazo fiche that are very
pale blue color, wouldn't be surprised if those faded.  They
were never intended for archival storage.
