The big blue cans are electrolytic capacitors. They have some very thin aluminum rolled up inside them along with paper soaked in an electrolyte. Not worth much as far as I know.

As dherik says break open some of those ceramic ICs, depending upon their age, they may have a fair amount of gold in them. Especially if they're ceramic.

You're right, I should have been more specific about which ones are okay to break. To whomever else reads this please don't damage or scrap chips like these two. The bottom one "C4004" sells for more than $1000.00.

Yeah I seen these before. There like rare Intel Processors

What about the smaller ones (dime size) and that size in pic, but are dark brown ceramic, on mother boards/ pci boards?? They seem to be in a plastic
holder but easily come out.....their value??

metal gypsy, the ones with the stripes red yellow brown gold? Those are carbon resistors, they are almost as valuable as charcoal briquettes.

Notice the legs on the chips though? and the metal bits in the sockets that the chips are plugged into? Gold plated, the older the board, the thicker the gold plating is.

Depends, but quite possibly. If you have the patience, older printers have pretty robust gears and motors which are sought after by robot builder hobbyists.

good pics of rare chips

omg...which is worse..I sold my 1966 Mustang for pennies in the early eighties.....or... I don't even remember what happened to my dot matrix printer along about the same time !!! Who knew ?!!

I looked in the first set of pic's and I think he's talking about the IC chips (which are dk brown or black) all over the board in the first pic. I think those are on plug-in sockets.

Some of the boards i pulled out of that old dot matrix printer, i have not seen ones like this before. Does anyone know what the ibm chip is? Srry about the blurry pic.

In the top pic. to the left of the blue can caps. is a big silver can cap. and right below it is a large transformer full of copper.
