The Vectrex is in no way the most popular console of all time, but it is one of the more unique. Eschewing typical raster-based rendering, it instead relies on a vector-based display. Since the average home television of the era would be completely unable to display such signals, the Vectrex had its screen built in. This got [Arcade Jason] wondering – would it be possible to hook the Vectrex up to a bigger screen?
First, a suitable monitor had to be found. The 19V2000 turned out to be a good candidate – much larger at 19 inches, and found in a variety of arcade cabinets from years past. From there, the project became a matter of identifying the signal outputs of the Vectrex. [Arcade Jason] took the liberty of modifying the levels of the signals on the Vectrex board itself, and then fixing the now-overscanned image on the original screen by adjusting the onboard trimpots. With the Vectrex’s X and Y signals now boosted somewhat, they were wired up to the inputs of the larger arcade screen. For the Z signal, things got even hackier – a Walmart “Computer Amplifier”, typically used for speakers, was instead pressed in to service to amplify the signal.
There are plenty of wires running all over the carpet in this video, but the fact is, it works brilliantly. Future plans involve upgrading to an even larger 23 inch monitor, and possibly even experiments with color vector displays. It just goes to show that the Vectrex, even today, maintains a die-hard following.
Perhaps you’d like to try this, but need to fix your original Vectrex screen first? Never fear – that’s possible, too.
Anyone else cringe poking around lethal voltages like that? I was waiting for the ZAP!
no but I cringed when you said “lethal voltages”
Lethal current, accounting for the skin effect.
Exactly. R of human skin is high-ish, and thus for sufficiently low V, I through the body is safe.
There’s a reason why AS/NZS:3000 declares >60V AC and >100V DC as “lethal”. Such voltage potentials would be present in that Vectrex cabinet, even in North America. That said, I’ll admit I really don’t like messing with voltages higher than about 30V, preferring to keep below 15V if possible.
The voltage only having “potential” to be dangerous… :D tehe
Yeah. I used to buy and “fix”(more like just swap parts around) arcade cabs in my garage and I was always terrified of the voltage in the screens.
The current’s really what kills you, but yes.
As the observer said to the mountain climber: “do not worry, the height isn’t dangerous, and falling down is completely safe, but be aware of the ground as it is the sudden stop that kills you”
Take precautions, wearing rubber gloves could help. Always make sure you are not standing in a puddle of salty water. And remember… you don’t have to touch those high voltage wires.
This is true… it’s more a case of accidentally brushing up against a conductor carrying a “high” voltage. The Vectrex is not a big unit and it didn’t seem there was a lot of room left when the camera was poked in there.
I=U/R
It’s the resistance that kills.
Its not the volts that jolt, its the amps that cramp!
That is a hack!
Did Vectrex play Space Wars?
If only there were some sort of searchable online catalog of information where one could learn the answers to such questions…

Pass the salt, and the crow, please…
Here ya go ;P

The most amazing vector arcade game was Battlezone. It was never made for the Vectrex, but featured amamzing 3D wireframe tank battle graphics.
Looks doable, but the orientation would be limiting

Nonsence. Star Wars with its colour vector graphics and multiple game sections was far more impressive. Rather more difficult to get to work on a Vectrex though.
If only there was a way to hack in a replacement dual op amp chip that is used to drive the yoke in original Vectrex. It’s a tad undersized for the use, Vectrex was originally going to be used with 5″ CRT but the big cheese wanted bigger so 9″ CRT was used with virtually no change in the existing hardware.
no change in the original hardware would be required since a 9” tube is physically longer than a 5” tube (longer beam distance) a larger picture would be on the screen.
hey guys i have a much better method to do this now !!!! i will post a new video showing how to do this on 3 different types of vector monitors on my youtube channel arcade jason
You continue to be a god of all things vector.
I have a Vectrex I got as a present when I was in high School. It was when Vectrex was going out. I used to play the demo at Musicland and loved it. They were discounted at King Norman’s Kingdom of toys from their original $199 down to $50.00 and the games were only $5.00. I don’t want to modify mine but would like to get it working again. I believe the only problem with it is the picture tube. When I turn it on I can hear all the sounds but there is only a dot in the middle of the screen. I have all my original games including the overlays which added color.
If you are having a dot on the screen then the picture tube is GOOD!
Have you tried tuning the brightness down?
