- Seems to me that DEC started emulating the instructions nobody used

- If you look at the block diagram (_EE Times_ I think) it looks like
- the CISC execution unit is a small part of the chip which is mainly
- RISC, cache, and memory control. I assume that if the chip is ever
- produced that there will be a new version of UNIX to use the RISC, and
- DOS will run beneath. Perhaps there's even hope that the "386 CPU" on
- the diagram could run in protected mode with some higher part of the
- memory access system keeping it from using most of the physical memory.
