+all their clones
I am wondering when more collectors find an interest in non-Intel-first CPUs. There are a lot of very nice chips out there.
And sometimes a clone is much more pretty than the original, eg. the SGS Z80 in "zebra" package which I rate higher than the purple original (I think the white "original" was made by Mostek).
But still now it seems that the major interest is in all those varieties of Pentiums.
And searching gold scrap boxes is really fun - keep everything odd, a collection of bizarre chips is also worth a peek! |
Thanks for the additions to the list. I had planned to put within the text included with the list that the CPU bulk lot should be scanned for anything with an unusual apperance that stands out from the rest of the lot, _especially_ dual-inline packages, explained to the reader as "chips with two rows of pins on either side of the package." It's the older CPUs that I'm personally most intersted in and is what I target in my collecting. |

Personally I think it is a good start but...
1. The scrapper would pick the gold out of their mud and raise the price, evinta1980 is a good example...search for Nx587 and you will know why
2. The condition of those chips are not garanteed, you will never know the chip is really the exact one or not, or worse, due to mishandling in computer scrapping process, the chip might get scratch, pins may be broken etc.
3. What can we do if scrappers pick all "ES" marked non ES chips out but sold as real ES, faking chip collectors? |
Thanks for all of the list additions. One of the fears I had after I created the first version of this list was, "Who is going to be willing to take the time to look for all of THESE?" The list can easily get so long as to be unusable. That's understandable since there have been such a huge number of CPUs/MPUs/RAM/ROM/EPROM types produced over the years. Perhaps the first rule mentioned for the searcher should be "first, separate out all of the non-Pentiums." _Seriously_, what would be some simple rules to help in the search of a huge lot of CPUs???
On your comments:
1. True, the big-lot scrap _sellers_ could eventually get ahold of the list even though it wouldn't be specifically sent to them (just the big lot eBay _buyers_ who resell their lots to their local gold reclaimers). However, as I've said previously, the small CPU lots I've purchased were sold by (probably) one-time sellers getting rid of home upgrade or PC shop leftovers. So, for those of us buying the small lots for collector value CPUs, I don't think there'd be any effect. For the _large_ lot sellers, it would only add to the market of available, collectible chips if they pulled out collectibles that would have otherwise been ground up.
2. I'll mention in the text included with the list that bent pins and scratches significantly decrease the collector value and must be mentioned in the ad. This goes along with my note to them that it is primarily the well-done ebay ads with good photos and knowledgeable descriptions that get the higher bids. This is intended to convince them that it would be in their best interest and would cause them minumum hassle if the'd just sell the more interesting CPUs in small eBay _lots_ OR, better yet, advertise them in CPU collector forums like this one.
3. Yes, fake chip markings could increase once more people know their value. However, the flip side of that is to let real ones get ground up. And we aren't talking about a huge number of people being notified about this list. This decreases the likelihood that we'd be notifying some scumbag who'd do this sort of thing. We're talking about a few of the largest CPU gold lot buyers on eBay. |

What's an ES marked but not real ES chip? |
For example
http://www.cpu-world.com/forum/viewtopic.php?t=1898
There are also P90 and P120 that i know of with the letters ES at the bottom.

To avoid such errors, I've removed all two-letter markings from the "text to look for" part of the list.
Thanks. |

I have saw a chip mark "TS".
Is it for 'thermal sample'?

The price of MG80286 is UD$50 in electro-market.
The price of MG80386 is UD$120.
They are new.
Are they expensive?

If you could get your hands on an MG0386 (Intel 386 military), I'll buy it or trade it from you.  |
