- The ZK plant was a Software Engineering
facility which opened in the early 1980s. The main entry
to ZK1, the original building in the complex, had black
and white bars arranged as 7 bit binary ASCII code.
Black corresponded to a binary 1 and white to a binary
0. if you look carefully, you will see a gap between
each group of 7 bars.
I recall it translated to "Digital Software
Engineering". Because the message would not all fit on
one line, there were two lines. The top line said:
"Digital Softwa" and the bottom line said
"reengineering". Those who knew ascii sometimes joked
about it saying, "Digital Softwa" "reengineering".
I found an old photo of the VMS team for the V3.0
release in front of the ZK1 main entry, You can see the
bars on the side of the building behind them. I am also
including a 7 bit ASCII translation table so you can
decode it for yourself if you like.
During VMS V3.0, I worked on the VMS terminal driver and
ASCII code was fundamental to my work, so I remember
this quite well. Fun to recall old Dec history. -- Rick
