Today's find

I havn't seen a computer like this before, it's labeled 25/486 made by Advanced Logic Research it was made in 1990.
here is a shot of the insides

the processor is on a small card and I have not been able to remove it from the socket, there was no heat sink

also , there seems to be lots of skinny memory sticks

has anyone seen one like this?

should I break it down into parts and boards like any other computer?

and should I try to pry off the processor?

if i remember right the ic chips arnt worth more than motherboard grade, is say sell it as is, do not pry the cpu off, just separate it out into motherboard, cards and ram and you will do fine

Ic chips are worth more than motherboard grade for me anyhow.

Thats a nice old 486 computer. Leave the CPU on the board and the ram chips once you pull them out will probable be the tin ram. Looks like 8 of them in there so its a cood scrap box in my opinion.

haha! if you don't research that one a bit, you deserve scrap price ; ) (i think tin ram is going for about $3?)

Thanks
not sure what "tin ram" is

I have been researching the cpu but have not removed anything else for a closer look, i did remove the ribbon cable for a better look.


why does the logo on the cpu not have DX etc. on it? I did see it in the serial/part number
every other 486 cpu photo i've seen has some other designation in the logo, but not this one.

I can't tell from the picture, but that CPU looks like it might actually be the type that does come off. I've come across a few that have a similar socket type and it might come off if you pry it off by sticking a screwdriver between the plastic socket and ceramic CPU and lightly twist it. Of course, I could be wrong.

I believe tin ram os .35 a oz

yes it looks removeable, i will try to gently pry it off, after i learn a bit more about it.

do they break?

If you look closer at the chip it does say as first set of numbers A00486DX-25

yes but all of the ones that come up on google searches have the DX with the larger intel logo, and yes i saw the other DX

you all can send me tin ram at $8 per pound, ill take all you have :cool:

the processor will break go easy i have broken them there big money that the 1's you want

sticking a screwdriver.........

hazard fraught toolz should still stock a vintage 1990's cordless manual adjustable left-handed spanner processor picker plucker puller kit tool which should work just as good as a screwdriver only gooder for bending......i mean keeping them pins uncrooked if you know what i ment.

ok.. so I got the Picker Plucker Tool over nighted to me! thanks for the tip!

I plucked it, stripped it, and its on its way to Ewasted! just waiting on the check!!

Just kidding, I decided not to pull the cpu, and put everything back together for now.

doing a bit of research, maybe this one shouldn't get scrapped.

thanks for the comment Bear, made me think!

A 486DX-25 means it is a 80486 CPU running at a whopping 25 MHz! The DX means it is the full chip that included a math co-processor built in. Intel made a cheaper version of the 486 that was marked SX, which meant the math co-processor was not built in and the cpu would be slower than a DX chip. The socket next to the 486 was a math co-proceesor or overdrive socket. If you had a 486SX, you could buy a 80487 math co-processor and plug into that socket to make your SX into a DX. You could also plug in an overdrive chip that would double the cpu clock speed eg DX2.

The ram is most likely 1 MEG each. The fingers will look silver since they were coated with tin, hence tin memory.

Ewasted buys mixed memory (tin, silver, and gold) at over $16 per lb. I don't know if he'd be OK with you just sending in tin or if you'd get the same price, but you might want to contact him about it

Mike, Thanks!
Scrapman, Thanks Too!
I'm not sure why this one looks like it should be left alone, a lot of old machines are being melted down.

I've scrapped a bunch, and I do it for cash and stress relief. I realy like demanufacturing. I make things for a living, so the high speed salvage opp is a great release.

I have some one who is offering to cover the scrap value +, just to avoid it being broken down, a collector, If they can afford shipping, she is 57+ lbs.

I have no idea what to value this one at. I don't want to take more than she is worth, but money is short, so giving her away is not smart.

Thanks again for the input

ebay would probably be your best place for selling at above scrap. Break it down into main board(with CPU & RAM), add in (finger) cards, power supply, case. Those are all easy enough shipped separately, and plain kitchen paper towels, in lieu of static bags, will help protect against static

did you maybe try a google search using the numbers from the mainboard? of particular interest in the results of that search will be results from ebay

Thanks again Bear
yes I did searches on several of the board part numbers, no info
same with company google searches

the cpu is of interest to me because of the logo printed in white large letters, most photos I find say I486DX

this one is just I486...why, is it an early model? and yes I saw the DX in the smaller print

I need the money, so I'll hunt down vacumn cleaners and carve some more bowls, maybe save this one for a while

if you were to sell this one off for someone else to scrap, what would you ask for? Don't consider shipping

would anyone venture a value
