PROBLEM
Starting with DOS 6.0 and now
into 6.2, Microsoft has eliminated
the Backup command and re-
placed it with MSBackup for
DOS and MWBackup for win-
dows.
I found this problem with
Dartman but I am sure other pro-
grams are running up against this
as well. As a temporary measure
you can use a text editor such as
Notepad and open the
Backup.bat file and change the
backup command to Xcopy.
A Twilight Zone pin was moved
in 20 degree weather and plugged
in immediately at the new loca-
tion. The dot matrix display now
jitters and shakes intermittently.
What can cause this symptom?
PROBLEM
DOS 6 users are experiencing
backup problems.
Although these backup utilities
look impressive, they will not ex-
ecute in the normal way. How is
this important? If you are using
Dartman II from Arachnid and
are backing up your data files
with one of the utilities included,
then YOU ARE NOT BACK-
ING UP!!!
This will copy your files in
uncompressed form to the se-
lected drive. I will report in more
detail in a later issue.

SOLUTION
Start by checking all the voltages
generated on the dot matrix con-
troller board. Make sure there is
no Ac voltage component on any
of the De voltages.
If it looks OK, then try swapping
the glass with any other Williams
or Bally pin with dot matrix dis-
plays. See if the problem travels
with the glass.
BRRRR
To actually answer the question
directly, the cause of the problem
with these symptoms is that the
game was plugged in and fired up
too soon after it came in from the
cold!
Condensation is the devil around
those high voltage circuits. (An
expensive lesson, I am sure.) In
the future, let that game warm up
a bit before applying the juice.
