Model M LED panel traces (assistance required)
« on: Wed, 05 March 2014, 22:42:07 »
So I have a model M controller that looks like this:


The four pin connector breaks out and connects to this LED PCB:


I was going to recreate the LED panel so I could add one to the above controller in question, but I can't find any photos of the LED panel underneath to recreate it. I just need to see the traces.
Any help would be appreciated, thanks.

Maybe this (not mine):

Thanks rowdy, that's exactly the right one.
I did a reverse search where the photos were from, and got this:




Totally cool, now I can create that LED panel. Cheers.

Cool! :)

Possibly someone here has a broken Model M, or perhaps one they used for parts, and might be able to give you a spare PCB.

Nah, I have the resources to make my own (I do a lot of projects and things that I don't talk about here). One of them creating and reworking electronics.

One thing that you'll notice is that the main controller board contains the resistor network for the LEDs! Earlier Model M boards, such as in my '86 one have the resistors on the LED board itself.

So really, to solder on LEDs, there are three positive pins (a positive wire going to each led), and then one universal negative one (which the LEDs then terminate to). Real easy.
The polarity could be the other way around, I'll know once I start building the thing.

Three LEDs and a connector - the olden technology couldn't be much simpler :)

So I anaylzed everything, and here's what I got.
You'll notice the ribbon connector has the main positive terminal much larger than the other three discreet negative paths to each LED


Time to heat up the soldering gear.

Unicomp may still carry spare LED boards too.
