- Actually this is a different case. Both chips can be configured to
- work on different bus sizes (foot in mouth if I remember incorrectly)
- Consider it from another angle (not to be sticking up for Intel but)
- Consider the cost of designing a whole new 16 bit chip. R&D, new dyes,
- etc. This is actually a brilliant idea (from their point), you forgo
- development time and testing using an already proven design to produce
- an inbetweener that fills a niche, gives people a more affordable machine
- etc.
