- Actually, I had thought that the Cy486SLC was a beefed-up _386_ (improved
- pipelining, on-chip cache, etc), designed to drop into a 386 socket. There are
- 6 instructions that Intel added to the 486 beyond the 386/387 instruction set,
- and NS486 makes very heavy use of at least one of them (a byte-swap
- instruction).
-
- I'm sure that when NS486 and the Cy486SLC are both on the market, we'll find
- out for sure...
