Pinball 2k video amplifier mod. Amazing! How to video.

I installed the Ultimarc video amplifier in my RFM and filmed the whole process.

This mod juices up the weak PC video signal and is a significant improvement. It drastically increases the brightness and contrast of the image quality. Its like a new monitor! Totally worth the $22.

Check it out:

The monitor does not output the 5v, the motherboard's integrated video card is what would output the 5v. You made at least two statements that the monitor has the 5v. My motherboards in my RFM and SWE1 both output the 5v needed.

>>The power supply should also be looked at!!!

The fan in the power supply go bad often, check this and that the power supply caps are good! These were made when the bad caps hit the market. My RFM had a stuck fan and bad caps.

There is also a battery on the prism card.

The CPU Fan should be replaced, as you said.

If you remove the PRISM card, you can plug a VGA monitor in and AT keyboard to setup the bios if needed.

For power going out of the PC box, I would use one of these. It's an external SATA bracket. This will make it so the power can be disconnected from the PC box easily. There are a lot of unused slots on the PC box.

Great video. I sure hope that thumb heals up pretty soon. Maybe that nail will fall off one of these days and a there will be a new one underneath.

If I said the monitor outputs 5v then that was a case of my mouth moving faster than my brain. :) Didn't mean it. :)

That SATA bracket is interesting. Nice idea.

I smashed my thumb good with a chair. Long story. :) You're not the first person to tell me my nail is gonna fall off. So far so good.

:) Ya, I figured. You said the first time it came from the pc, then switched it. Hey shoot me a pm, I should have one of those brackets here somewhere, and I will send it to you. My boards were nice enough to supply the 5V.

Another method of delivering the 5v. You could find the pin that needs the 5v and run a jumper wire to the header on the pcb. So a wire would run from the power supply header to the vga header. But this would involve pulling the motherboard.

Thanks for the offer! I tapped into a molex and it's working fine. I installed a quick disconnect too. Don't really want open it up again. :) Thanks though! !!!!
