It was rbrooks that mentioned this. I have not seen posts from him for a while though.
are you sitting on a stash? if so, please take a picture of them, and let us know where you found them. Knowledge is power! Thanks for sharing!
Here we go... I know for sure I have 48 of these guys as there setting right besing me on the "to look up or list on ebay shelf"...lol.. I have no clue how many i have for sure... They are out of arcade machines or lottery machines..

cool! I just took some out of the "Memory cartridge" form some old calculators too. I'm guessing that's the Rom the game resided on maybe? If you get a buyer please PM me as well. not that I probably have more than a couple.....
i sure will sir...
Nice picture....very pretty chip.
Here is the link (see below) for an EPROM parts supplier selling the same chip shown in your picture.
Price: $6.45/chip (not per pound)
Link: http://www.futureelectronics.com/en/...001-80XF1.aspx
The webpage indicates he has about 800 in stock, so I imagine these chips must have multiple applications that are still relevant (otherwise, why stock so many?)
I found another link for a different supplier selling a closely related EPROM chip (part #M27C4001-12F1 vs your part# M27C4001-80XF1)
Price: $7.69/chip
LInk: http://www.alliedelec.com/search/pro...x?SKU=70014186
I hope this helps to give you some ball-park pricing reference points.

Any luck selling your eprom mr metal? I have about 20 of them but they do look a little different then yours. It appears in your picture that the little square under the window is gold and the part around that is silver. On mine the little square is silver and the part around it is gold. Am i seeing things in your pic? I may have to go back thru my bucket im pretty sure i have a several like the one in your pic.
That is not a gold window IC chip. Just a standard ceramic IC.Quote:

Yes, I do believe that those shown in the picture are not gold cap in the middle. My buddy runs a traveling video game exhibit with 100s of old school games and he had me zap some of those chips with UV light for him since those windows when exposed to UV erase the memory of the chips and them them be reset in the game software somehow.
heres a pic of mine

How many of those eproms to you sell to get 90 bucks? Where they collectable or just selling as scrap?
I beleive it was 40 of them. They were sold as replacement parts as they were new..
And I just picked up 2-3000 E-proms testerdat that go to telecom equipment... But when you take off the paper over the glass ,, ultraviolit light will erase these E-proms and they can be reloaded...and reused.
Today, I got 30 gold eproms and about 60 with a silver looking window and 3 with gold legs. They came from arcade games in the 80's. They where on giant boards with gold fingers. I will see what they pay at the buyer today.
So i guess ripping them out with a screwdriver is not a good idea unless selling for scrap, eh?
the gold e-proms are like the ones piced above .that have a visable gold backing behind the window .not in the center
There are special tools for pulling them for reuse. I have seen them, but Don't remember where.Quote:

You get great looks.
I just got a call to buy older mother boards, devalued ram and the such. Guy had gold fever for a bit then snapped out of it. ha Anyways he said he has close to 100lbs of IC chips and a bunch of Eproms (gold or ceramic, not sure yet). Is anyone currently buying these? I searched sellers page a bit with no luck. Hoping the guy doesn't want $1M for all this... he mentioned $6/lb for the IC's... not a good sign. If I can find pricing I'd feel better making an offer and sticking to it. Thanks Guys!
PS I'll post pics when I can view the stash
Sounds like he wants to get rich without doing any of the work.Quote:

He can get $5# for ic chips if he ships. Offer him $3. It would come out to that after shipping costs. Also take a good look at those motherboards, if he defingered the ram he probably pulled stuff off the boards too.
Hey, you guys should probably define the differences in windowed (UV erasable) IC's.
Basicly if you look in the window you will see either Silver or Gold.
There's two places you will see these metals, the wires or the background of the silicon IC.
So, the wires will be Gold or Silver.
The background under the IC will Silvery or Goldish. The background metals are actually heatsinks for the square IC.
So...
1 Gold wires and Gold background
2 Gold wires and Silver background
3 Silver wires and Gold background
4 Silver wwires and Silver background.
Now that you understand that Gold is used as a heatsink.....
Look at the computer CPU's. Find the ones with a Tinned Copper plate over the cpu.
The sort of cpu that you find on later computers, smaler and sometimes legless.
Under that copper cap, you will notice a metallic smear there.
Its either silvery or goldish. Same deal as above. There can be gold under those caps.
That's why the escrap buyers will take them as is, there's a chance of gold.
Now, its not worth taking the caps off unless you know thrss gold under it and have a buyer as well...
I made the made the mistake of thinking that as I get copper price for the caps, that it would be worth my time to take them off. I lost a few $$ doing that...
