Supergun RGB question

[Geezer]

I'm wiring the video output to RGB as described here:

http://www.chads.arcade.btinternet.co.uk/Supergun/video_connection.htm

It says to connect +5V to pin 16 via a 100ohm resistor. Problem is I don't have a resistor
Will it work without the 5V? or do I have to wait till Monday to get one

Just wait... the resistor is there to drop the voltage. 5V may be too high.

That resistor drops the voltage to <3v for auto-switching TVs. Don't connect anything to that pin if you just need to test it, you'll just have to switch modes manually (ie the TV won't auto-switch to RGB).

Thanks for the info guys
I reckon I'll wait as I like the autoswitching feature

That resistor drops the voltage to <3v for auto-switching TVs. Don't connect anything to that pin if you just need to test it, you'll just have to switch modes manually (ie the TV won't auto-switch to RGB).

Be careful, there are some European TVs (I've met some) that won't display RGB unless they receive voltage in that pin, so you can't manually switch to RGB.

So I strongly recommend to have that pin wired to +5V through that resistor even if your TV doesn't need it.

Yup, whenever I want to use my RGB-modded N64 (which isn't very often), I have to activate teletext to force the TV into RGB, because it does not include an explicit RGB mode...

I just got some resistors from my dad but I can't tell what ratings they are. Does anyone know how to interpret the coloured lines?

100 ohm is brown/black/brown.

It turns out I've got some 100 ohm resistors after all

I've got 5 band resistors, not 4 band ones thats why I was confused
