red or green or yellow light A500

Vaninna · 21 June 2016, 14:05

I did a search on this rather basic question but didn't find the answer, sorry for being lazy:

I got two A500: one has a combination of green/yellow light for power/drive, and the other one has a red light in the combination (do not remember if it is for power or drive. I think it is for power. And it is deep in the wardrobe).

What is the difference, else than the colors?

I haven’t seen a yellow one, if you mean changing the red LED to orange they did it after a certain year,
probably when the orange LEDs were as cheap as the red ones.

idrougge · 21 June 2016, 14:10

Red light ones are older, I think.

Jope · 21 June 2016, 14:14

Yep, it's just the age. Some time in the 90s they changed to green for power and amber for drive activity.

Vaninna · 21 June 2016, 14:34

Ok, so there is no difference under the hood. Boring.

Personally I think the red light is cooler.

My A500 has a red light. It's baddass!

xArtx · 21 June 2016, 15:08

I think a red LED can’t be an A500+, but orange LED doesn’t mean it has to be A500+.

I never saw an A500 with buddies that did not have a red power led. But then all my buddies bought their A500s between mid 87 and mid 89.

My ´91 had orange.

Wow, that is a very weird function, seems very unnecessary. But cool.

On my green/orange Amiga it is the Drive led that is orange, not the Power led.

In models after the Amiga 1000 (excluding the very first revision of the Amiga 500), the brightness of the power LED is used to indicate the status of the filter.
The filter is active when the LED is at normal brightness, and deactivated when dimmed (on early Amiga 500 models the LED went completely off)"

remember the SCA Miami Vice sounddemo intended for A1000, where they would blink the power led on/off throughout the demo, but if played on an A500 it would screw up the sound due to the filter kicking in/off all the time.
Solution was to put a small led util inside the startup-sequence so the led would stay permanently off on non-A1000 machines. I had to try a few led tools before I found the right one that would really force the led off all the time.

The keyboard/LED PCB of the A500 has the LED colour printed on the silkscreen. Question is if the silkscreen was changed to coincide with the LED colours.

Red LED for kickstart 1.2 machines, and Yellow for later 1.3 revisions.

I fear it is not as easy as this. When I bought my first Amiga 500 back in the days it had a red LED and Kickstart 1.3

I still prefer red power LEDs on my Amigas today - as ransom1122 said, it looks a bit more badass / evil / cooler

Nope. Mine was august 88, rev 5, 1.3 and red power led. (Was a warranty exchange of a 1.2 machine bought in June 88)

Jope · 23 June 2016, 07:14

Let's put the led colour vs. Kickstart discussion to rest. :-) There's plenty of kick 1.3 machines with a red led.

1.2 + red + power led goes off = rev3 or early rev5
1.3 + red + power led goes off = upgraded rev3 or rev5
1.3 + red + power led dims = rev 6

There is also the question about the capslock color

My first A500 (that I still own) have all red LED's (even capslock), and it also have a C= button instead of left Amiga button. (This means it have the old type of keyboard, that is much nicer to write on than the new keyboards.)

dirkies · 23 June 2016, 12:16

My aug88 1.3 still had red caps lock led. They probably changed at the same time as the other leds.

Jope · 24 June 2016, 15:41

In my experience, the caps lock LED is the same colour as the power LED, unless of course someone has changed it.

This is a keyboard from an A500+ rev 8A. You can see the silkscreen says "PWR RED", but the LED is actually green.
