is there value in intel 8088 cpu's and older

so i have alot of boards from the early 90's and some that are even older.

i have removed alot of cpu's from the boards
the ones i got include 286/386/486 and newer

what i would like to know is if there is value in the older chips and what there prices are per lb.

some of the cpu's i am trying to put a value to are ones like these

intel 8088
intel 8086
intel 8008
intel math co-processor

what other cpu's and valuable chips should i be looking for in the very old boards

thank you everyone in advance

if im not mistaken they sell for the same price as the 286/486 at ruffly $120 a pound.

Glad you asked. I always look at scrapping as the last resort. Much better if you can sell as collectible or for reuse. Some resources that I know of that may be of help.

Here's a wanted list of various old chips/cpus with some descriptions

A resource for computer chip collectors:

There's a list of old computer collector values at

Good Luck!

I just found this page from a link here & decided to post it.

Gold value in Computer Chips

http://www.chipsetc.com/gold-value-i...ter-chips.html

AMD Athlon K-7: 0.08 grams
AMD Sempron: 0.08 grams
IBM 586: 0.1 grams
Intel 486: 0.1 grams
Cyrix 486: 0.11 grams
Texas Instruments 486: 0.11 grams
AMD K-6-2 (with gold cap): 0.11 grams
Intel Pentium MMX: 0 .12 grams
WinChip C6 (with gold cap on underside): 0.17 grams
Cyrix MII: 0.18 grams
Intel 486 (with gold cap on underside): 0.2 grams
Cyrix 686: 0.21 grams
Cyrix 586: 0.25 grams
IBM 686: 0.25 grams
Intel 80186 (with gold pads & cap on underside): 0.27 grams
AMD 80186 (with gold pads & cap on underside): 0.27 grams
NEC R10000 (with gold cap): 0.27 grams
Toshiba R10000 (with gold cap): 0.27 grams
Intel early Pentium 60 to 90Mhz (with gold cap): 0.48 grams
AMD K-5 (with gold cap): 0.50 grams
Intel Pentium Pro (with gold cap): 1.0 grams

These values are not accurate and this site along with another that posts the same values have been under scrutiny by the goldrefiningforum. Their values for example are consistently around the 0.3-0.5g for the pentium pro. Whilst a part of the value may be lost in processing and refining it is highly unlikely that 50% of it just 'hides'

what price would buyers buy these old chips at?
$120/lb ?

i have alot of intel 8088 cpu's and plenty more old chips on the motherboards.
i would like to know which other chips should i pull out that are in the same price range

and what about integrated cpu's
these are old 286/386 cpu soldered directly to the motherboard.
should i remove them or sell with the boards.
will they also go at at $120/lb

what price do bios chips sell at?

thx for any input.

btw please pm me and recommend your favourite e waste buyer.

Great find - thanks! Sure I know amounts can vary, blah, blah, but this is a good starting point to determine the total value of gold in CPUs. Once you know that and if you know the weight of the CPUs, you can get a good estimate of the amount of gold in a pound of given CPUs. Then we are all better prepared when we're offered an amount for our scrap CPUs. Here is another site I found with similar info.

Between the two we should get somewhere :)

Thanks!

The first time I give you information that is correct. -that these figures are not just varying but downright wrong and I get a "blah blah blah". You speak of the discourtesy you recieve yet when information is given to you that you don't want to recieve you respond like this??
Another prime example of how skewed these figures are is when you compare the weight of an aluminium top amd k62 processor to the very similar weight of a i486 chip. Alledgedly the amd k62 contains 0.11g per chip at a weight of 21.5g each, giving a yield of 5.1g/kg. The i486 at 23.5g containing 0.2g per chip yields 8.5g/kg
According to this, the i486 worth up to $145/lb means that the AMDk62 metalcap is worth 60% the value of an i486 at $87lb. Now which buyers here pay even half that for them??? Are they secretly and knowingly conspiring to pay us less on these chips? I think not.
If this figure is so screwed up how can you possibly believe any of the others are remotely true. This therefore has no other purpose than to give misleading information in peoples expectations of yields, thus has an adverse benefit to being shown.
