MONITOR TYPES AND DIFFERENCES
Now that we have discussed the operating theory of the Cinematronics monitor, we need to note
the different types. There are several revisions of the Cinematronics ‘vectorbeam’ monitor.
However, there are two distinct versions – the “discrete” HV version and the “Keltron” version.
The table below outlines the different revisions that are detailed in each schematic package. Do not
assume your game has the original or correct monitor in it! Operators (and collectors) are known to
swap things around. Also note that these monitor revisions are different and independent from the
CCPU revisions. Do not confuse the two!
The monitors produced by Larry Rosenthall’s Vectorbeam company are for all intensive purposes
identical to the monitors made by Cinematronics and differ in name only.
Cinematronics
Space Wars Rev. A (‘discrete’) 19” B&W monitor
Star Hawk Rev. B (‘discrete’) 19” B&W monitor (some with 23” B&W monitor)
Sundance Display with 16 Level Intensity – Rev. ?? (‘discrete’) 23” B&W monitor
Tail Gunner Rev. D (‘discrete’) 19” B&W monitor
Rip Off Rev. B (‘discrete’) 19” B&W monitor
Star Castle Rev. G (‘Keltron’) 19” B&W monitor
Armor Attack Rev. G (‘Keltron’) 19” B&W monitor
Solar Quest Display with 64 Level Intensity - Rev A. (‘Keltron’) 19” B&W monitor
Vectorbeam
Space War Rev. H (effectively a Cinematronics Rev. B ‘discrete’) 19” B&W monitor
Barrier Rev. H (effectively a Cinematronics Rev. B ‘discrete’) 19” B&W monitor
Warrior Rev. H (effectively a Cinematronics Rev. B ‘discrete’) 19” B&W monitor
Speed Freak Rev. H (effectively a Cinematronics Rev. B ‘discrete’) 19” B&W monitor
[The Vectorbeam monitor has an extra 2n2102 (Q19 on the Vectorbeam monitors; Q8 on
a Cinematronics - 2N3904)]
Exidy II
Tailgunner II ?
Rock-Ola
Demon Rev. ?? (‘Keltron’) 19” B&W monitor
[Boxing Bugs and QB-3 (you have one of those, right?) each used a Wells-Gardner 6100 color
vector monitor. War of the Worlds was supplied as a kit and was intended to be installed into a
Star Castle or Armor Attack. A couple War of the Worlds prototypes used the Boxing Bugs color
adapter board with a Wells-Gardner 6100 color vector monitor. Therefore, none of these games
are included in the above list.]
