  • Product Description

    Note: This model is not for use with original Mortal Kombat II or Killer Instinct cabinets.  

    Large, bulky and heavy CRT monitors have seen their time come and go, giving way to lighter, thinner and higher-resolution monitors and TVs.  With that, older consoles and arcade motherboards are not capable of producing the video signal used by today's technology.  That leaves most desiring to upgrade their arcade cabinet to flat panel LCD, design a supergun, or play older consoles on a newer TV needing a bridge between the two worlds.

    The Gonbes GBS-8220 (v3) CGA/EGA/YUV to VGA Arcade HD-Converter PCB is considered one of the most popular video upconverters on the market.  It is designed to accept and process various video signals from older systems, such as EGA, CGA, VGA, and YUV component, and output as high-resolution VGA signal.  Often coupled with a separate sync cleaner module for the cleanest RGB signal, and SLG (scan line generator) PCB to recreate the look of older CRT monitors, the GBS-8220 is an incredibly versatile solution.

    Direct from Gonbes

    A significant number of upscaler clones exist in the market, with questionable construction and video output quality.   Please be assured that the GBS8220 model we carry is purchased direct from Gonbes, and an authentic part from the company.
