- The Cyrix 486SLC has a 386SX pinout, which means it has a 16 bit data
- bus. The 486SX has a 32 bit data bus. Considering the smaller cache
- in the Cyrix, I would expect it to be much slower than the 486SX. The
- Cyrix 486DLC will be closer, but still slower than a 486SX, mostly
- because of the smaller cache, but also because the 486SX bus can be
- faster than the 386 bus of the 486DLC chip.

- OS/2 2.0 will do for me until AmigaDOS for the 386 comes along...
