- What I cannot reconcile is that a 50MHz i486 (~15MIPS) chip costs
- ~$500 (in quantities of 1000) while the new SPARC chip that Sun
- has produced with TI, costs ~$150 (SPARC2 speed ~30MIPS); with this
- new chip the whole computer (video, IO, etc.) can be designed with
- 12 (yes, twelve) support chips.
