Diagram of Jumper Settings
Note: Jumper J3-1284 does not effect monitor type and may or may not be present.
Note: The Vectrex display is very sensitive, and the Size adjustments alone do not have
the range needed to shrink the screen enough to be usable by the Vectrex. The utility
ZVGTWEAK.EXE will need to be run, and the ‘Screen Size’ parameter lowered in
order for a Vectrex to be usable as an X/Y display. The ‘Min’ and ‘Max’ values will
also have to be adjusted using
ZVGTWEAK.EXE.
The following ZVGTWEAK.EXE settings work well with the Vectrex:
Z-Axis Shift: 50
Z-Axis Overshoot: 45
Maximum Intensity: 255
Minimum Intensity: 140
Point Intensity: 30
Screen Size: 85
Jump Speed: 35
Settling Time: 1
