PROBLEM
PROBLEM
Have a Atari Hard Drivin' that
will not load. Screen comes up
Download error, ASIC 16 error,
Generic error.Just had the board
in for repair, it worked for two
weeks then back to doing the
same thing.
If you have the following prob-
lems with the game, this is due
to an improper ROM revision on
the PCB.
THE
SYMPTOMS WOULD BE:
Have checked ALL voltages;
they are all within specs. I do not
know what the service shop re-
placed or repaired. Can any one
help.
* Random freezing
SOLlITION
* 500/o of the G RO Ms test bad
Most problems of this type of
board are bad connections. Just
take all the boards out and reseat
all socketed parts and headers.
Check for bad soldering on these
boards as well. My bet is that'll
cure your intermittents.
The new version is the 1.65. Any
older revisions would need to be
updated. Please contact your lo-
cal distributor for more informa-
tion and availability .
* Screen fogging
* Bad video RAM testing

MACHINES AFFECTED
PROBLEM
All CD-lO0F Phonograph's prior
to SIN 6729.
I have a Lord of the Gun game
made by IGS and it keeps knock-
ing out the Voice EPROM, What
I mean by knocking out is that it
would work once then there
would be no more sounds on the
EPROM. I can erase and reuse
the EPROM again ( and I did try
a new one). Any Suggestions.
PROBLEM
Noisy Color Tubes on the Lower
Door.
SOLUTION
Install new style End Cap
Field reports have indicated cases
of excessive noise and wear, com-
ing from the bottom End Cap
Plate Assembly rubbing against
the fluorescent Bulb in the rotat-
ing Color Tubes. Rowe has rede-
signed the Assembly to eliminate
this problem.
The End Cap Plate Assembly (2
per machine required) can be
ordered from your local distribu-
tor.

Your problem could be two
things , your programmer maybe
not set at the right manufacturer
and or the timing not set prop-
erly . This is important when pro-
gramming EPROMS or they
loose their data when they try to
drive the data bus .
Another could be you have your
field ground and common con-
nected together. Separate them!
And make sure they are not con-
nected any where else in the
game. (Check the coin door this
is a popular spot where grounds
get mixed up!)
