i486SX: Room for the future with built-in upgradability
|This key chain is supposed to have a die of Intel 486SX processor. The die
looks exactly the same as 80486DX die in a keychain below.
Either this is a die of 80486SX engineering sample (some of them had
disabled FPUs), or it's a die of 80486DX processor.|| || |
Quality and Technology: Intel486 Microprocessor
|Front side of this keychain has "Intel Inside" logo.
Back side of the chain has a die of 80486DX CPU.
"Intel Inside" program was launched in 1991 - two years after the 80486DX
processor was introduced. The die has approximate size 10mm x 16.5mm, that is
about 165mm2, and it was manufactured using CHMOS IV technology.|| || |
Quality and Technology: Intel486DX2 Microprocessor
|Front side looks exactly as the keychain above. Back side has a die
of 80486DX2 processor. Size of the die is much smaller than the die of 80486DX processor -
about 7mm x 12mm, i.e. 84mm2.|| || |
|This really big keychain (2" x 2", or 5 cm x 5 cm) looks like as if it has a
real 80486DX2-50 microprocessor inside. In fact, the front and back of the processor
are printed on paper, while an actual chip die is glued to the paper. The size of
the die in this keychain is the same as in the keychain above.|| || |
|This is the only 80486 keychain in collection that doesn't have rectangular shape.
This keychain bears "Intel Inside" slogan on the front side, and a die of 80486DX
microprocessor on the back.|| || |
The 486 Business Workstation - Intel486 Microprocessor
|This keychain has the same silver-colored die (same size)
as other 80486DX keychains on this page. On the bottom of the back side
you can see not very well known Intel slogan: "The computer inside".|| || |
|Front side has a picture of boxed Intel overdrive processor. Back side has
a die of overdrive processor. The die is not distinguishable in size and
layout from gold-colored dies of 80486DX2 processors on this page.|| || |
The Intel Overdrive Processor
|Another 80486 OverDrive keychain. The die has the same size as in the keychain above.|| || |
