For Hackaday readers which might not be so well versed in the world of home video gaming before the 1983 crash, the Vectrex was an interesting attempt at bringing vector graphics into player’s living rooms. Priced around $500 in today’s dollars, the machine was unique in that it included its own black and white CRT display rather than requiring the owner to plug it into their television. To spice things up a little bit, games would include a thin plastic overlay you could put over the screen to give the game faux colors. What can we say? It was the 1980’s.
Like many vintage gaming systems, the Vectrex still commands a devoted following of fans, some of which continue to find ways to hack and mod the system nearly 40 years after its release. One such fan is [Arcade Jason], who’s recently been fiddling with the idea of creating a modern take on the overlay concept using a hacked LCD display. While it’s still a bit rough around the edges, it does hold promise. He hopes somebody might even run with the idea and turn it into a marketable product for the Vectrex community.
[Jason] started by getting an old digital picture frame and tearing it down until he liberated the LCD panel. By carefully disassembling it, he was able to remove the backlight and was left with a transparent display. He then installed the panel over the display of the Vectrex, leaving the picture frame’s PCB and controls dangling off to the side. Extending the display’s ribbon cable should be easy enough for a more robust installation.
He then loaded the frame with random psychedelic pictures he found online, as well as some custom overlays which he quickly whipped up using colored blocks in an art program. In the video after the break, [Jason] shuffles through images on the frame using the buttons on the PCB while loading different demos to show the kind of visual effects that are possible.
While a neat concept, there are a couple of issues that need to be resolved before this could really be put into practice. For one, the LCD panel isn’t the proper size or aspect ratio to match the Vectrex display, so it doesn’t cover the whole CRT. It’s also rather difficult to select images to show on the LCD panel; an improved version might use something like the Raspberry Pi to load images on the panel while exposing a control interface on a secondary screen of some type.
