    What would you do with some of these boards and Grade type?

    mostly all have double sided gold fingers and some boards have lots of gold pin connectors, some all the way to the board . a couple of close up pictures im looking to see if they are tantalum cap? i have 48 photos in this link that are from a prison security system i recieved along with a trailer load of other goodies. yes that is a box of about 6 or 8 units of 911 dispatch panels. thanks for the help. oh by the way the yellow chips soddered like all the others, im guessing thats not tantalum neither..

    here is the link to the photos. https://www.dropbox.com/sh/vwz1dxavk...BpYRDS-ha?dl=0

    Different buyers grade, and pay out, different amounts for boards.
    Get prices from several different folks, don't just go with the first offer you get.

    On a side not: some of that stuff is not sellable as-is unless you break it down ( lamps, relays, e.t.c. )

    Tantis normally have the positive pole (+) labeled. Other caps have the negative pole (-) labeled.

    The bigger yellow blocks are relays, look for the boards ink printing for that item 'RLY' or such. Those will have tiny 'Gold bar' contacts, probably Gold plated Silver bars.

    the lamps and relays was just shown for what i recieved from the pickup. every board has fingers (tall ones) and they are old boards. just curious if that type of quantity of fingered boards vs the downgrade of the board if i should trim them. Im sure the silver pieces i zoomed in on are tant caps the sister same cards have orange not silver ones. the orange bullet kind of piece that i think is tant cap to. but thanks for the info anyhow.

    Nether one is tantalum

    The ICs are worth a bit of money if you can carefully desolderer 'em
    Examples I seen:
    Motorola mc14538bcp
    Worth about $0.50 each
    Motorola mc14011bcp
    Worth about $0.60 each

    Some of the other parts are worth money such as the
    Aromat ds2e-m-dc12v relays
    Worth about $0.90 each

    Most of the boards have too much "heavy stuff" attached to them to be worth much to a buyer. The fingers can go for up to $2 an ounce last I looked, however it's going to take a few of them to make an ounce.
