qwerty12 --

you could accidentally slip that copy towards me, as well, and you'd not hear a peep of complaint!! ;)

Well, from the picture, I cannot tell if the connector is being viewed upside-down or not. I assumed not. Then I assumed standard pin-numbering, beginning on the upper left (not pictured) continuing to #25 on the top, then starting at #26 on the lower right corner, and proceeding to the left towards #50. :)

Understand there are no silkscreen markings on the PCB... was wondering if there was a "pin 1 indicator" on the connector itself. Sometimes, it's little more than a tiny dimple at/near the #1 connector... that's why I asked if you had a (high res) photo of the entire connector.

I spent a good deal of money in school, studying electronics engineering, only to subsequently springboard my "career" from my (hobbyist) background in computers and programming... and then relegating all that education, largely, to hobby activities! ;) It is fun, mind you, designing and building all sorts of nifty gadgets, etc... and (when possible) repairing the odd bit of electronics here and there for friends & family...

Say, your PM box is full. I'd not mind a copy either. ;)

Re: need advice on soldering on my n800!

I'd appreciate the item qwerty offered as well. It appears the forum supports file attachments and links. ;)

Re: need advice on soldering on my n800!

Ok, well, largely thanks to Briand, plus finally being able to at least discern a starting "C" from a starting "R" on the blurry schematics, along with some deduction, I know precisely which three components I need. I nearly lost my eyesight yesterday trying to solder a scavenged 1meg resistor into place (sort of), but now think I'll adopt a different tack and see if I can't attach an auxiliary mini-board with larger components, attached to the three required points (+ ground) using very fine magnet wire, perhaps. I've found a little "pocket" where I could place this. I won't get to this for a few days, but I'll post back my results.

Re: need advice on soldering on my n800!

good deal!

would love to see a photo of the finished work, as well... and I promise not to criticize your breadboarding technique. ;)
