Finding himself in need of an arcade monitor [Eric Wright]
turned to this ancient CRT television. The problem is that
arcade monitors and televisions didn’t operate in the same way,
differing in both resolution and refresh rate. [Eric] modified
the television to work like an arcade monitor, but only with
limited success. He’s hoping a few more alterations will lead
him to a complete solution. The image above shows him testing a
Pac-Man machine on the altered Sharp television. Those familiar
with the game will immediately notice that there is something
wrong. We see most of the tracks upon which Pac-Man and the
ghosts travel, but he maze itself is completely missing. To get
to this point [Eric] consulted the television and arcade
schematics to figure out how to connect the composite sync and
three color channels directly to the arcade machine. This way
the CRT timing is forced to conform to the game standard. The
problem is that there is no way to adjust the drive and cutoff
of the individual color channels. T
