Did the 286 have a 287? Was there floating-point code in the

I don't know, but I remember comparing two side-by-side and the 286
absolutely horsed the 386sx. IIRC it was about 15% faster - *really*
noticable difference. Harris Semiconductor made licensed 80286
CPU's.
They made them in 16 and 20mhz versions.
I used to sell systems made with them, and at the time the 386sx came
out, a 286-20 was MUCH faster than a 386 20mhz...
How is that possible? The 386 improved many instructions to run in
fewer clocks...
Besides, I'd always take a 386-16 over a 286-20, because the 286-20
runs protected mode applications at 0MHz ;-)
