Star Tech Journal

Foreword ...
In an effort to get their games to market quickly,
manufacturers sometimes ship without support
documentation. Games are being received without
wiring diagrams, schematics, or even the self-test
procedure included.
Even the best made, thoroughly tested machines
have a percentage of initial failures. An otherwise
locally-solved problem now places an additional
burden on the operator, his distributor and
the manufacturer's customer service people.
Perhaps a little coordination on the manufacturers'
part would eliminate this small but important
oversight.
