80826 is Coppermine.. and 80825 is Katmai
but dont think there was any 512k Coppermine 
EDIT>> just looked at Intel documentation
QB78 was a qualification sample C0 stepping 550MHz 512k Katmai SECC2 package

Yes, it was due to wrong part number. I fixed it. Thank you for the correction!

Perhaps, having two separate pages for basically the same processor was not a good idea. They have minor differences, like different package type and the maximum temperature, but the rest of the specs are identical. I think it makes more sense to merge them together, than to keep two separate parts in the database.

You have done that with SECC2 & SECC3.0 packages in slot Pentium IIIs
so I dont see why not

posted a link to CPU-World 8080 page in VCF
http://www.cpu-world.com/CPUs/8080/index.html
comment made
Interesting page, but with a couple of problems: It lists the 6800 as "related family". And says that the Z80 has an 8080 emulation mode.. I've always believed that the Z80 is 8080 compatible, there's no emulation mode (unlike e.g. the 65C02 emulation mode of the 65C816, or the 6809 emulation mode of the 6803).
And writing "flow" instead of "flaw"..
my response back
Will talk to site owner about Z80
guessing 6800 related only as both are 8-bit and released at same time
With regards "flow".. that is correct.
The flaw with the 8080 was that it had a flow
Will ask him to make this more clear.. maybe expand with definition of flow
on a side note.. it made me realise that this site has copied your content with no acknowledgement

The Z80 is infact binary compatible with most 8080 code has 8080 compatible registers etc.
It adds significantly to the 8080 instruction set and capabilities though (has additional registers and bit manipulation instructions to name a few)
Was thinking it was only object code compatible, but most 8080 binaries will run on a Z80
Remember, it was designed by the same man (Faggin)

About binary compatibility:
yes, most binaries will work exactly the same.
Except ones using opcodes 0xCB, 0xDD, 0xDE, 0xDF.
In 8080 they are just alternatives to existing commands:
0xCB is equivalent to 0xC3 (jmp a16)
0xDD, 0xDE, 0xDF are equivalents to 0xCD (call a16).
It was not recommended to use alternative forms.
In z80 they are used for additional instructions coding:
0xCB for shifts/rotations and bit operations,
the other three for string operations, additional arithmetics,
data move with additional indexing modes with IX, IY registers.

And about 8080 compatibility mode, z80 has it!
But only in the sense of interrupt controller,
there are three modes, 0 is for 8080 compatibility.
It's nothing to do with the code. |

"Emulation" was obviously a bad choice of a word. I replaced it with "compatibility". Z80 description didn't require any changes as it correctly stated that the CPU is compatible with the 8080.

I noticed there are no notes for SL2KE.. these are from spec update
4. VCCCORE is specified for 2.0 V +100/-70 mV for these Pentium II processors.
7. Cacheable address space supports up to 4 Gbytes for these Pentium II processors.
8. These processors will not shut down automatically on THERMTRIP#.
12. This is a boxed Pentium II OverDrive® processor with an attached fan heatsink.
on PODP66X333 main page you have Vcore listed as 3.3V
not sure if this the same as VccCore (2.0 V +100/-70 mV)
The CPUid for Q0125 is listed as 0631h
I would expect this to be 1631h (TdA1 stepping)
The processor core for Q0120 & Q0125 is listed as Klamath
but from from spec updates notes.. I think it should be listed as Deschutes
3. This is a Pentium® II OverDrive® processor. Please note that although this processor has a CPUID of 163xh, it uses a
Pentium II processor CPUID 065xh processor core.

Not sure if you have replaced your original D4004, but this statement seems a bit erroneous
This ceramic 4004 is dated 45th week of 1976.
The FPO is saying week 03 1981.. bottom likely to be 8101 or 8102
a Intel product from week 45 1976 would have a lot number around 2354A
