debugging the protect circuit

phe · #1 07-11-2007, 05:47 AM

Problem Solved!!!

There was a manufacturing defect

in the board and two traces were shorted. A bit of work with an exacto knife and I was able to remove the copper bridge between the traces.

I've attached a jpeg of my handiwork.

Now I have a finished Altair.

Thanks for sticking with me guys to figure it out.

(Gee --- all I have to show for this, from a demo perspective, is a switch that turns an LED on and off

)

Yep. Marty was right. I didn't understand the problem.

Oh well, at least his system is up and running!
