Those cheap upscan converters you see will only upscan a composite signal. You could go the route of making your 15khz rgbhv signal into composite and then use one of these cheap boxes. I don't know off hand which IC will build a composite signal.
I have the XRGB-2 unit from Micomsoft. Its expensive at $250, but it does a professional job of upscanning an RGB signal via the Japanese scart input (that 21pin connection). They are supposed to come out with a XRGB-2+ unit which will handle component in (probably make it more expensive) if you want to wait on that.
But if you plan on making this a project just for your jamma board, I suggest going to composite upscan route.

: Anyone have any suggestions on how to connect a video game pcb directly to a pc vga monitor? I'm seeing inexpensive video-to-vga converters (or line doublers) that advertise tv, dreamcast, etc. inputs to vga outputs. I've even seen a more expensive model from Micomsoft that has a 21 pin rgb input. Anyone had success with these? I was hoping I could wire my rgb and negative composite sync wires into one of these cheaper boxes via svideo or composite inputs.
: I want to add my Boomer Rang'r pcb board (unmamed game that I just had to have) to my Mame cabinet under construction (which will use a 21" vga monitor). I was thinking I might be able to supply the 5V and 12V to the pcb board from a standard pc power supply. Any thoughts there also?
