Here is a list of identified components at this point.

 

Are the HP parts (1820-, 1853-, and 1854-) new?

Are you looking to sell, barter, or give away? What's your location?

Would gift some, want to sell some. Yes, many of them were HP components. Have much more than were in the spreadsheet.

HP parts are mostly salvaged

Would you mind updating with the condition in the spreadsheet. Also indicate which are free and what price you want for the rest.

And add more of what you have available. The small numbers of parts you have listed aren't worth buying unless I had a specific need. For new old stock parts, they might be worth buying to hold. I have a number of them listed in the barter thread for people repairing HP (and Tektronix) gear.

 

Most of the components listed on the spreadsheet were salvaged from PC boards that did not pass test. Therefore quality cannot be guaranteed. Probability of any of these individual components is defective is very low. Any component that had been removed from a PC board would have the leads formed for mounting. For example .4" for small resistors and diodes. If the quantity of any item on the spreadsheet is not listed the quantity is 1. Hundreds of transistors and IC's have yet to be identified. It is time consuming and I may never get it done. I also have hundreds of resistors (carbon comp, film, wirewound, board mounted trimpots), capacitors (ceramic, film, electrolytic (mostly tantulum)), diodes (small signal>power). I also have a small quantity of voltage regulators. I would donate much of what is of low value, and any item that is shown as quantity of 1 and is not of common use. I would charge a very reasonable price for components where value can be checked against similar items for sale. I am very new at using this type of communication, and easily get confused. I would prefer a different form communication if that is possible.

But anyone using them can't know for certain that they're good, making it a gamble. Troubleshooting might not be as much of a bother for an experienced person, but it'd still be inconvenient. For an inexperienced person, they might not even know where to start troubleshooting.

I understand. I took weeks/months to compile the listing I made in the bartering thread and I received little benefit from it.

Salvaged components will likely have more value to the person who actually salvaged them. For others, it's rarely worth the bother of buying them, or accepting them for free, because they're an unknown and not very expensive to buy new.

I used to buy used EPROMs/FLASH to refurbish and sell on eBay, but gave up when it got so expensive to sell things there and counterfeiting became such a big problem.

 

My take on this, if the parts are used and salvaged from boards, they are of zero or negative value. It is not worth the time and effort to mount them into a project board to find out that they don't work.
Resistors and diodes pulled from a board are not worth anything. I would say, bin the lot.

 

With all of that having been said, I have salvaged components. ZIF sockets, LEDs (frosted 5mm, some 3mm), some TO-92 transistors, and some DIP capacitors. All of which are relatively easy to test.

 

And I also salvage SMD resistors from scrap boards. I don't desolder them and store them. I only take them off the board when I need a particular value that I don't have in stock.

 

The value of salvaged parts is directlt related to the cost to that individual of new parts. For some folks it makes a whole lot of sense, and no sense at all to some others. It also depends on the time and effort required to recover the used items.
Of course, some recovered items may no longer be available new, or they may be very high priced new. Not everybody can ignore the purchase price of some components, while for some others a high price is not an issue.
