- This is pure speculation, but it seems to me that any upgrade path
- would be via a plug-in daughtercard rather than a pin-compatible
- replacement that you could plug into a 486 socket. A number of
- motherboards are built with the CPU and cache on a small daughtercard
- that plugs into a special slot on the motherboard. This makes it easy
- to upgrade the CPU by a simple card swap. So it should be
- theoretically possible to upgrade this type of system to a P5, though
- I wouldn't count on these systems to perform as well as one that was
- designed around the P5 from the ground up.
