None of the 386 models had on-chip FPU. That came with the 486.

Moreover, there was an 80387SX copro to go with the 386SX.

  And, for us oldies the Weitek as well as the DSP32 board. https://en.wikipedia.org/wiki/Weitek https://en.wikipedia.org/wiki/Weitek and https://www.signalogic.com/images/Ariel_DSP32-PC.jpg https://www.signalogic.com/images/Ariel_DSP32-PC.jpg

    And if you're old and a bit odd, there were i486+i860[1] motherboards from (at least) Hauppauge, Microway & Olivetti. [1] https://old.hotchips.org/wp-content/uploads/hc_archives/hc02/3_Tue/HC2.S6/HC2.6.4.pdf https://old.hotchips.org/wp-content/uploads/hc_archives/hc02...

      I never got my hands on one of those. But I did get to play with Transputers, which was another interesting co-processor option.

        Transputers are still a thing from ST Micro, I think, though targeting the embedded market now. I got to use a Meiko 'Surface' transputer supercomputer back in the day. Interesting toy. The i486+i860 combo I played with ended up being not particularly interesting. By the time it showed up, Pentium was eminent so the i486 was old news and the i860 was a huge pain in the ass to get anything like promised performance out of.

        Meiko, there's another name that I haven't heard for a really long time. Are there any Transputer based systems still in use?
        kjs3 5y ago
        Yeah...the Meiko was pretty nifty, and Occam was an interesting language. Like I said, ST Micro picked up the Transputer line via acquisition. They morphed it into more of an embedded product, and targeted things like set-top boxed. Pretty sure it was the ST20 line. Unfortunately, a very quick look at the web site makes it look like ST did what everyone else in the embedded world seems to be devolving to: everything is an ARM. So...there are probably descendants of Transputer still chugging along out there, but doesn't look like it has a future.

      I remember learning "Hauppauge" was pronounced "Hop Hog"
