Author Topic: keyboard LEDs (Read 2966 times)

Two questions concerning LEDs.
1. Does anyone have a list of the games that actually use the keyboard LEDs?
2. If a game doesn’t use the keyboard LEDs, are the LEDs on by default or off?

Thank you.

dont have an answer to #1, but for #2 the that all can depend on the keyboard you have, plus the motherboard. check your bios to see if you have num lock - enabled or f lock enabled on startup, if so, these led's will be on as soon as the os starts.

Well I'll start the list and someone else will have to add to it...

pacman
ms. pacman
centipede
tempest
gravitar

as far as keyboard leds they can be configured in your biois--I turned my num lock off on bootup since it is attached to my coin up buttons and I didn't want it glowing all the time.

the keyboard LED's are just for looks or do they have some function in games. I certainly dont remember Ms Pacman requiring any kind of light

they flash when you add credits--what nerd could resist flashing led's on their machine?

Some games will flash player 1 and player 2 coin up. The best example I know is Out Run. There is a LED flashing for the start button and when you brake another LED lights up. You could hook these up to leds/lights on your cab and add some realism.

asteroids, all of them
Centipedes.

A lot of old atari games had those cone buttons.

ALL Atari games (up unti what, mid 90's??)
Most or All "Kee" Games

turbo
omega race
outrun (lights come on with the brakes)

discs of tron - one led lights up to simulate the interior black light coming on and off. and one led lights up when your player gets killed by sark.

victory - in attract mode all three leds light up in an alternating pattern.

But MAME will turn them off when a game that doesn't use LEDs is playing. Some other programs, like DOSCab/WinCab Jukebox, may do the same.

Same topic, different question for you folks:

If I have a 2-player cabinet, with one lit button for player 1, and one lit button for player 2, is there any use in installing the 3rd LED somewhere??

Bgnome · « **Reply #14 on:** July 21, 2004, 12:46:47 pm »

i, for one, could never have too many LEDs..

Anyone know what the average voltage on a keyboard PCB for the LEDs is? I would guess 5v, and I'm sure I'm wrong.

It is 5v. I tested it a while back because I was bored and had a multimeter.

Then the existing LEDs on the PCB must have a resistor inline. Hmmmm....

Depends on the keyboard. I've seen them both ways...

I'm actually thinking of putting mine in the marquee to light up certain parts brighter like the back glass of an pinball machine.

I wouldn't bother. The only use I have seen for the third (ScrLock) LED is Ajax flashes it when you have a special weapon, but it also displays that on the bottom of the screen.
