As mentioned above, This was brought as part of over two large vanloads of bankrupt stock, these were held on-to to keep my machines going, now they are being moved on this collection can go too. As far as I know these all work. Thes descriptions are as accurate as I can get them there may be mistakes! All is packaged in an anti-static box and arranged so every chip is in foam (I sorted it out after the pic was taken) This is a sizeable chunk of Amiga history in this box. Add to this one item (390563-01) looks older than the rest and doesnt apear on chip lists although its older -02 part brother does, its quite possible this a beta chip or evaluation part.

That is NOT anti-static foam that those ICs are in. You probably have damaged all of them. I saw those on eBay and decided not to bid on them because they are not pressed into black anti-static foam and placed inside a sealed silver anti-static bag. Those chips are easily damaged by static electricity that you can not see or feel. My advice to the people looking at those ICs, DO NOT BUY THEM !!!! :-o

Actually, that could be anti-static foam. It looks exactly like the anti-static foam that was used by the contract electronics manufacturer I worked for last year. The foam we used was a 3M product. BTW, I *KNOW* the stuff we used was anti-stat for two reasons:
1) 3M said so
2) UL wouldn't have allowed the company to keep its ISO9001 cert if the stuff wasn't anti-stat.
The lack of a desicant is abit troublesome. I'd wager that the pins on those IC's have oxidized enough to prevent solid electrical contact. But concidering that these buggers have been around for a few years, I doubt it matters much.
Too bad the auction in the UK. I'd bid on it if it were on my side of the pond.

To N7VQM:
I saw them on the USA eBay. That foam is NOT anti-static. Anti-static FOAM is BLACK. :-o

Not all anti-stat foam is black. Some is pink, some is black, some is yellow, some is even white. It depends on who made it. The colors I mention are just the ones I've seen. It's by no means an exhaustive list. Anti-static products are not limited to bags and that black foam junk. All that black (which also doesn't have to be black) stuff really does is hold parts in one place. It's quite useless beyond that. Have you ever seen anti-static bubble wrap? I think it has a better popping sound than 'regular' bubble wrap. :-D
To be honest, unless those parts were handled only at static-safe workstations by properly gounded people and transported only in static-sheilded containters, the possibility exists that they have been damaged. They could be damaged by static EVEN IF they WERE properly handled. It can happen just walking across a properly-outfitted factory floor, following all the rules. Such is life.
Now, re-read my first reply, especially the part about ISO9001.
-
Hummm... But even if 50% of those chips were damaged (and I doubt they are), wouldn't £5.00 be a good price to pay for all that? :-o

To Oldsmobile_Mike:
I think that they are ALL damaged and no, the price is not worth it on static damaged ICs. People must learn to take the proper precautions when handling static sensitive electronic components. The number one cause of IC failure is static damage. There are 2 kinds of static damage done to ICs- immediate and gradual failure. Immediate static damage happens right away. Gradual static damage usually takes about 3 mounths, this is the reason for the typical 90-day warranty. The static electricity that a person sees and feels when touching a door knob after walking on carpet is between 3,000 to 10,000 static volts. The amount of static electricity that it takes to damage todays modern ICs is less then a person can see or feel. Many electronic components can be damaged by just 25 static volts. You do not even have to actually touch an IC or Board to zap it, they can be zapped from up to 3 feet away. So it is very important to always plug ICs into black anti-static foam and place them inside a sealed silver anti-static bag. Boards should also be kept in a sealed silver or black anti-static bag. White and yellow foam generate up to 10,000 static volts, so yes, these ICs are zapped and I personally would not trust them. :-o

Buy ANTI-STATIC FOAM in a wide variety of colors here folks. Including Sexy Pink!! (http://www.brownpackaging.com/foamsheets.htm)
They claim it's Anit-Static, but clearly it's not possible being that it's not Dyed blak.
--Edit:
They also claim it's "[color=CC0000]ISO 9001-2000 CERTIFIED[/color]". I wonder if that means anything?
-
Of course maybe you meant something more along the lines of [color=990000]Lead Insertion Grade Conductive Foam[/color]??

Sorry, but I couldn't resist one more:
Chip Boxes -- Available at http://www.corstat.co.uk/Products/enlargements/chip_boxes_elg.htm (http://www.corstat.co.uk/Products/enlargements/chip_boxes_elg.htm)
Isn't it cute? Pink and Black right next to each other :)

Wonders never cease are these millitary grade? ;-)

@ amigaguy
for ICs is necessary "Conductive Foam".
Antistatic foam (used for packaging), is not enough.
Ciao
-edit- available in pink/white also.
-
@ DoomMaster
There's no need to be so sensationalistic about your announcements. Anti-static bags and foam come in all sorts of colours, colour does not affect static conductivity....
-
:-o
-
I don't want them! They're not military grade! I buy all my military grade chips here:
(http://www.pgordon.clara.net/militarygrade.jpg)
They come wrapped in yesterdays black anti-static newspaper...
:-D :-P

I got my old K6-2 CPU in grey anti-stat foam. I highly doubt that AMD would sell chips that isn't in anti-stat foam...
-
well i doubt i would have buyed thoose chips even if it had said.... ALL TESTED TODAY AND ALL WORKS.
why? because i would have no use for em ;(
cheers

If you think that anti-static foam is made in black color only, you're clearly mistaken. What you say might have been true 10 years ago but not anymore.
You make me wonder if your whole character is a joke, that you do this for fun or something.
If you are for real, well.. With statements like that it's no wonder people are prejudiced against americans.
Just look at what manufactures today ship their computer parts in. Is it black foam? Mostly not. Here, I've seen pink for the most part, and I can tell you for a fact that none of my parts have been 'zapped'. Sun Microsystems ships their servers in White anti-static foam..

@Doommaster
Man I cant take it any more. I didnt want to say anything about you, but you need to stop and do some research before you post mate!! You are wong here and we all know it. Stop making yourself look like an arse. I have used and see anti-stat foam in ALL colours you could ever think of! That goes for bags as well. No hard feelings ;)

Amigamad, mate:
"1 X Unknown CBM ROM 390388-01
1 X Unknown CBM ROM 390389-01"
I believe these are A1200 specific OS3.0 Kickstart ROMS. theyre a pair. (who says you dont get nothing for a pair in this game ?!)
can anyone confirm ?
-

I think what you are really refering to here is a Latent Failure. Here is the definition of a Latent Failure:
A defect or damage that does not show up until some time after the damaging event occurs. The initial damage is not sufficient to cause catastrophic failure of the device, but does weaken the part. At some later time, either another static event or the cumulative effects of previous static events finally cause the part to fail.
This definition comes from HERE (http://www.static-planet.com/products/).
This has absolutly nothing to do with any 90-day warrantees because a latent failure could happen at any time in the devices life.

To N7VQM:
You are wrong about that. Pink foam is NOT anti-static, it just does not GENERATE static-electricity. Pink foam does NOT protect ICs against static damage, black foam DOES. In all the years that I have worked in the electronics / computer industry I have never seen yellow or white anti-static foam. :-o
-

Presumably because it is pink?

You can't have dealt with that many hardware suppliers then.
After someone else's Athlon comment, I decided to check the packaging of mine (which I keep the CPU I upgraded from in), it is also pink. I bought the new CPU from cclcomputers.co.uk.
-
To mikeymike:
Pink foam will not zap the IC, but it will NOT protect it either. There may now be many different colors of the "pink foam" but they do not PROTECT the chips from being zapped. Only the black foam does that. You see, what makes the black foam black, is that it has carbine in it, which is conductive (same as the black anti-static bags). Since I am a Class 4 Electronics Assembler and have worked in the electronics industry for many years, I have dealt with many hardware suppliers. The reason why they ship ICs in the pink or white foam is because it is much cheaper then the black foam. But they will usually also have them packed inside a black box or a black or silver anti-static bag. The pink foam is ok, just as long as you put it inside a protective box or bag. :-P

The black foam doesn't protect very well. Only static sheilding (like a static-sheilded bag) will reasonably protect a component. Black foam is not static sheilding. It helps but if you carry a voltage-sensitive device stuck to that foam through a strong enough electrostatic feild (such as that surronding a computer monitor or electric motor), that device could be toast unless it's INSIDE a static sheilded container.
Granted, the black foam generally is better than the other stuff (which is usually just low-tribocharging rather than conductive, you just have to read the datasheet to make the determination) but neither one alone is enough to protect components.

Of course it does and amd get nearly all there cpu,s returned because it Dont work. :-D :-D :-D

Regardng static damage, for these components I wonder how likely that is. At least the kickstarts are probably ok.
Why do I say this? Well, my recently assembled 1200D is using a pair of old kick 3.0 roms that I had stuck pin first into a block of expanded polystyrene for 4 years. They were in a bag in a drawer for all this time and they really are fine....

How come my athlon had a pink/white one? It was definitely not black.

What about all those screenshots people just posted? I doubt a serious company like amd would use anything other than anti static packages for their cpus..
