Ok I'm a moron. I thought it was 1995. Then I see it's 2005. You're absolutely correct.
Q029 must be recycled. |

I just acquired two of these and have done some searching as well as compiling of information. You can thank Jerome for his major contribution to this info as well as the comparision photo.
There is a difference between the chips I found and LZF7000's.
LZF7000: A6239303AA
New Ones: A6239293AF
Speculations
* Gold plated CPGA chip has an expensive package fitted for heat dissipation which points to it being a cpu
* the datecode doesn't match with Pentium (1993), Pentium MMX (1995) or Pentium Pro's (1995) development, but match with PII's one
* the pinout seems to be in the continuity of the Pentium Pro's pinout
* the pin count could match (more than pre-PII CPU's, less than post-PII CPU's)
* as the package is smaller than a Pentium Pro and the pin count higher than a SECC PII, it could be the main PII chip without L2 cache
* why without L2 cache ? because after introduction of the Pentium Pro's expensive package, Intel may had already decided to mount it on a card with cache chips all around
* why not a Celeron ? This type of expensive package wouldnt make sens for a low-cost processor
* they are a lot of similarities between this CPGA and a early PII BGA sample on the last picture (the "A" plant, A-1/A-2 stepping markings...)
Who has been asked about this chip
-Contact In Malaysia who has access to records was sent the numbering from both my chips and LZF7000 chips and nothing was found.
-Current PAL manager at the Intel Phoenix site
-Two of the previous PAL managers from the Hillsboro Oregon site who worked for Intel during the time of this chips development.
What Intel employees remember about this chip. This info is from 2 or more sources.
-It was a cpu
-The project was canceled very very early on.
-There was never a motherboard developed for it, just an adapter card.
-All but 5 chips were scrapped.

Nice!
it seems LZF already sold it
i am curious how much he will ask for if he still has it

I just noticed the numbering on a very very early Klamath chip shows something very interesting.
Numbering on the two Q029's is A6239303AA & A6239293AF
Numbering on a early A-0 Klamath A624924CYA
Numbering on early A-1 Klamath A630016CYB

Oh I didn't notice this new post. Very interesting! What do other collectors think of that?

I will put my 5 cents in on a old subject 
The production date is 9623 by both die & FPO
ES A1 stepping Pros (copyright 95) were produced from 9609 with first production 9619
ES B1 stepping Pros (copyright 96) were produced starting 9645
looking at Intel acronym terminology used on their chips
A8 CPU/Core No Internal Cache
A >> Ceramic package
8 >> ??

A wild guess...
It does make sense (at least to me) that Intel might originally wants to get that expensive (and yield reducing) L2 cache OFF the PPro package and back to motherboard again by this chip
There was adapter card, not motherboard, that existed, hints that chance that the CPU was of a completely new (or differ than x86) architacture is small (although it is not impossible)
That narrows it down to derivatives of existing chip design....
I would take the whole picture as a cacheless PPro, that drops onto a adapter card that have onboard L2 cache, and in turn drops into existing socket 8 motherboard, more or less like a PII overdrive...
Perhaps Intel found some major problem with such design, and opt for a new slot instead?
more wild guess....
A8CNIC = A 8 CPU Not Including Cache |
