- What in the world gave you this idea? Do you have any clue how long it
- took Intel to make the 486/50 chip so it would run reliably at 50mhz? The
- 33 was out LONG before the 50, and is not, and never was, simply a
- rejected 50 chip.

- Truly an interesting question. Also...what's the status of a 486dx2/100?
