> Hell, until the Pentium, Intel CPU's weren't guaranteed to even have an FPU.

80486

486SX

The 80486SX was introduced two years after the 80486 and did not have an FPU (unless it was purchased as an option).

I think the meaning of my comment was clear: the 80486 was the first Intel CPU guaranteed to have an FPU. I didn't say all the Intel CPUs which came afterward were guaranteed to have them...

My first "my own purchase" PC was a 486sx. So as a _line_, "the 486" wasn't guaranteed to have an FPU.

I guess that's true. I never really thought of them as the same thing.

Looking over some old info about the "i486" (I swear I had completely forgotten about the i) was a treat. It's only barely believable but I think the sheer annoyingness of Intel's marketing and market segmentation might have actually peaked three decades ago.
