(Probably incomplete) List of products from the "GBS" family and use cases.

[M--S]

So, I think everyone knows about how the GBS-8200 was created as a way for arcade operators to replace CRTs with LCD monitors, but there are many other products from the same line that could be helpful for us. So here is a list of the ones that I know about, and if anyone knows about other ones please inform it in the replies.

GBS-8200: Cheap video upscaler, RGB/Component/VGA in and HD VGA output, can be upgraded into a GBS-Control.
GBS-8220: Version with two outputs.
GBS-8118: 2 boards JAMMA switcher.
GBS-8100: VGA 31kHz to CGA 15kHz.
GBS-8219: Industrial VGA box.
