I found these boards mixed in with a lot I bought. As you can see there is a lot of gold plating/pins on these. They say "1972 Tektronix, inc. I realize prices vary by buyer, but I need a general idea. I have never dealt with boards like these. Thank you.

well first i would test to see if they plating that is on the board is gold or not.
But just looking at the components i would say low grade

nice looking board. You might do better with a collector, or ebay. Did you try googling the company ?

Well, it looks like you have some reading ahead of you.Originally Posted by anonymous
ANYWAY, I would say high grade, but Bear's suggestion should be the first avenue for these boards. I would hate to see these scrapped.

It looks like some of their stuff goes for more than scrap on Evilbay. RARE Vintage 1972 Tektronix Inc Computer Breadboard Circuit Board Original WOW | eBay

if that is really gold plating on the board and not just a gold colored solder cover then yes high grade. Thats why i said test it first.
But looking at just the components, its all large resistors and ceramic capacitors. I see a couple gold pin transistors too, but i assumed if scrapping those would be cherrypicked.
Anyways could you explain why from just the components you would grade this as high grade? Im new here as well and would like to observe others grading methods.
Also bear is right, probably can get more from a collector than just scrapping it.

haha, low high grade. If that's true it looks like they both were right ; )

If I were to grade all of my boards by just components, then most of mine would be low grade. But I (and most of us here) don't grade on that, but grade by gold content, fingers, and "hidden" gold. You could also call motherboards low grade by just grading on components because you cant see that much gold, but there is gold that you can't on the surface. If I had a board that was all capacitors (the silo things) but it had gold contacts, it would be a high grade board. I am pretty sure most of the buyers on the forum would give you some kind of high grade pricing for this without testing it.
Also, there is no "Gold colored solder" on that board. The "Solder" on that board is normal colored solder. The gold color you see are gold traces, and are usually copper on low grade. These boards have large gold plated areas and all of the contacts are gold plated, placing it higher on the grading spectrum.

That's high grade board $3-$5lb. that bottom board with all the gold tracing is $5lb. Also looks to have heavy amounts of silver solder. Not that silver has any value to refiners.

why wouldn't silver have any value ?

I think he's being sarcastic.

When they refine if I'm not mistaken, they try to reclaim all the good PMs' and silver is one of them.

Yes that was sarcasm. It just seems that when grading a board people tend to forget that silver although its value is lower, is also considered in a boards grading. There is a lot more of it on high grade boards than gold. About 15 times as much. So like Bear I'm all about the silver.
|
There may be more on the board but the Ag to Au ratio is 52:1 so at 15X's as much it still worth 1/3rd of the gold content. for a board refiner this is something they pay on on the dore bar assay.
