I would say it is like Wells Gardner, Sega, and Atari trying to design
the exact same
circuit. Most everyone has their own way of looking at a problem and
coming up with
different ways of solving it. I would also very much like to see a new
deflection
board and HV board that would be compatible with all of these monitors.
Parts are
getting scarce for some of these units, and if you do not have an
extiguisher by your
GO8, there could be some trouble. I am not an electronic engineer, so
all I can do is
offer some of working knowledge to getting this underway. As Al pointed
out, certain
aspects to the design have to be addressed first. I am glad he is
finding some time to
do research on the current monitor boards used in these games. Finding
the usable
parimeters and designing to those specs.
