Close encounters of the CADR kind

       > How do you figure that?

   Umm, because I saw them every day, for several years? :-) (They were
   scattered all over the 9th floor at Tech Sq.)

   Admittedly, it's hard to tell a picture (from the front, where one can only
   see a giant wire-wrapped assembly) of the CONS machine from a picture of a
   CADR, but that one also has the CADR header-plate.

Fair enough! And muchas gracias to Al as well for his response!

   Also, from a previous message:

       > these pictures are of a CONS, or a very early CADR prototype

   There were no CADR prototypes, other than the CONS.

   The first CADR built was, I am fairly certain, put into service as a general
   user machine; it likely had fixes applied during the bring-up process that
   were built in from the start on later machines, so they were all identical
   (i.e. no special software for that one machine), but there was no 'prototype
   CADR' left lying around gathering dust, unused.

Thank you! I'm basing my observations from ploughing through the CADR
source code, schematics and old incomplete mailing list archive.
