what type of processors has high Yeiild Gold

I found some great information for those that needed a little help..



This list is a list of HIGH Yield Processors. These are the one You wanna find....

• Intel 186 / 286 / 386 / 486 / Pentium / Pentium Pro / i860 / i960
  
• Cyrix 486 / 586 / MII
  
• IBM 486 / 586 / 686
  
• Motorola 68000 / 88000 series
  
• NEC & Toshiba MIPS series: R4000 / R8000 / R10000 / R12000
• AMD 286 / 386 / 486 / K5 / 29000 series
• IDTWinchip C6 / 2A
• DEC Alpha
• HP PA-7000 & PA-8000 RISC series
• SUN SPARC / UltraSPARC / SuperSPARC RISC series

Modern computer chips manufactured after 1998 have very little gold content in them because most CPU's no longer use solid gold wire bonding technology or gold-plated lids in their packaging.

For example, the Intel Pentium 4 Microprocessor came in an organic (non ceramic) package with a nickle-plated copper lid, & it did not use gold wire internally to attach the silicon chip to it's package. It's only noticeable gold content came from it's connector pins that were thinly gold-plated. However, the pins were gold-plated to a thickness of only 0.76 microns - that calculates to just around a few cents worth of gold value per CPU.

Today, a typical organic CPU package no longer is made with connector pins, instead they use thinly gold-plated connection pads which is used to socket the CPU to a motherboard.

SOME MORE GREAT INFO.

Most popular with chip collectors are the early Intel microprocessor chips such as the first microprocessor - the Intel 4004, and it's successors - the Intel 8008 & 8080, as well as early Intel Memory chips such as the first RAM - the Intel 3101, ROM - the Intel 3301, & EPROM - the Intel 1702.

The Intel 4004 microprocessor, especially the white ceramic version - the Intel C4004, continues to be the most sought after computer chip by collectors today.

Other popular chips that collectors are seeking are the Motorola 6800 & 68000 vintage CPU's, Mostek 6502 CPU, AMD 9140 RAM chips & other early AMD chips such as the AM2501 logic counter (AMD's first product) and their 8080, 8086 & 8088 CPU's, as well as any early 1960's and 70's integrated circuits and hybrid circuits that are in white ceramic packaging with gold leads & lids.



Even among modern CPU chips their are still ones worth saving from selling to the gold recyclers. Especially popular by CPU collectors are any chips, old or new, marked with "ES", "Engineering Sample", or "Mechanical Sample" on them. These chips were preliminary versions of the chip, they were given to vendors by the manufacturer to test out future designs before being offered to the general public.

However, chips marked "Confidential" or "Internal" were never intended to be used externally by vendors or the general public and should not have been available to anyone outside the original manufacturer, these chips should be avoided by sellers and collectors and if found they should be returned to the original manufacturer. As rare and valuable as these chips may be to collectors, their are legality issues to owning and selling these chips on the open market. They will always be property of the original manufacturer.

Here a another great site for great information..

I was am still am looking for info on this very rare chip .. Its a 64 pin lead purple cermaic, and gold pins .. I've yet to find info on this particular item
The Info on the chip is a AMI 8231JF s9900

if anyone can assit Me that would be great.

Just me, but I don't turn any chips down, whether their on a list or not.

I wouldn't either.. but just giving a short break down on what is more valuable and what is what.. just a little FYI for the new people out there..

Just tring to educate people.
