Intel 80P23T-25 Q607 ES
Looks like an overdrive chip, but the heat sink could
be custom marked
|
|
Intel A80486DX- SXE61 ES
Supposedly, this Intel 486 DX is an Engineering-Sample because of the ES
marking in front of the model number. No speed marking- yet has an
S-Spec that begins with S, rather than Q. This makes it an unusual chip.

Intel A80486SX-16 SX431
First and slowest speed released for the 486 desktop CPU series. Intel
486 SX running at 16MHz, lower power chip.
|
|
Intel Pentium PCPU3V90 SZ978
Intel PCPU Processor running at 90MHz with a 3V core voltage.
|
|
Intel A80501-60 SX835
Intel Pentium running at 60MHz- has the world "PROCESSOR" printed
beneath the Intel Pentium Logo. This CPU has the FDIV bug. What makes it
rare is that Intel took back a majority of these "PROCESSOR" versions,
trashed and replaced them with regular Intel Pentiums.

|
Intel A80501-66 SX836
Another Intel Pentium with the "PROCESSOR" logo. This one has the FDIV
bug and runs at 66MHz.

Intel Celeron FV524RX366 Q827ES
366MHz Intel Celeron Engineering Sample.
|
|
Intel FV524RX400 Q958ES
400MHz Intel Celeron Engineering Sample. |
|
Intel
Tualatin 533MHz ES (Unknown Q-Spec)
No markings were made on this chip. Chip posted at
533MHz. |
|
Intel RK80530PZ866512 QCU4ES
Intel PIII-S Tualatin Engineering Sample, running
at 866MHz with 512k L2 Cache. |
