Help with old chips (values)

[vintage-computer]

Sorry if this is in the wrong place, but I have questions!

I recently came into a rather large collection of old chips and I'm trying to figure out what I've really got.

Much of it will probably end up on the VCGM but I want to know (in general) what stuff is worth first.

Here, for example, is a small sample of the CPUs (most of the rest are controllers, TTL, RAM, etc.)



The five on the left are various 8085s (Intel, NEC, AMD and unknown - plastic and ceramic), the three on the right are a Signetics N8X300I, a TI 8080 and a Zilog Z-80.

I've found a few chip collector sites like this one but none have pricing/valuation information!

Any help would be appreciated.

Welcome Erik!
you have a great site and great vintage-computer collection.actually ,your vintage-computer-forum is one of my favorite and i am also a member there

speaking about the chip value
my opinion is that
the most valuable chip of these chips is the Ti8080 (if it is the right middle one).
if the chips are all in good condition
the ceramic 8085 is possible 5-10 USD
and the plastic ones is about 1-5 USD each
the Signetics N8X300I is used to be 10-20 USD
but the Ti8080 is at least 20 USD and possible easy to be higher than 50USD on the ebay if in mint condition (as for referance ,white ceramic intel 8080 used to 50-100 USD on the ebay)
regards!

Hi Erik,
I'm a member of your group also and I'll give you a basic primer about CPU's based on my relatively short timespan in the chip collecting hobby/addiction.
GENERALLY Speaking-
Chip values can vary based on Age, Rarity and type of chip material (plastic, brown or purple ceramic, white ceramic and Gold pins or tops.
Plastics are usually the least collected type, however many early Intel and other well known CPU brands and even support chips are desirable if they are scarce or rare types.
Brown and Purple CPU ceramics are more collectible and Gold trimmings and rarity add to the collectibility. I collect some older pre-1985 small "brownies" or "Sandwich" chips just because I find them interesting.
White ceramics with Gold tops and legs AND unusual large chips or chips with unique top designs seem to attract the most interest. They are usually older discontinued CPUs and some support chips and it seems that fewer of these were made than of the plastic or other ceramic chip types.

Again, These are very general guidelines and I'm sure one of the expert members here will give you detailed info on your pictured chips on a following posting!

Ciao....

It depends why you are collecting... If you value them according to looks then this formula is spot-on.

Also based on the mechanical and electrical requirements of the more specific (ie military, aerospace / industrial / prototype) and therefore potentially rarer chips that are of the ceramic type, these guidelines also hold true.

I'd rate the ti 8080 much higher, of course the picture doesn't show any details.

That is a nice 8080! I have not come across a white ceramic one before when documenting known TI chips. Can i ad your image to the database? http://www.chipdb.org/cat-8080-992.htm

Ti 8080 in white ceramic are present in Genna collection, CPU-Museum and (if I remember well) in ITO-Family collector site in Japan

I think are also in other collection not documentated on internet

always a nice chip along with OKI 8080 white

There appears to be enough interest to justify an auction so I listed it on the Vintage Computer and Gaming Marketplace.
