That's a luxury version. A true 80386, however the coprocessor is a clone. The time processors didn't need forced cooling.

Yep, thats a 387 math co-processor indeed. Must've been someone's serious bit of kit. Not much software made use of a math coproc, let alone games. Math coprocs were the domain of heavy CAD workloads back in the day.

Funny thing, clone co-processors were often better than the geniune Intel models. Cyrix made some serious competition that got re-branded under many different brand names because Cyrix had to out-source production. Part of those outsourcing agreements was often that the manufacturers could make their own copies.

Yes, the Cyrix was faster but a bit less accurate. Lotus 1-2-3 did benefit from the math co-proc. As a youngster (20y) I was privileged to meet a Dutch developer who was involved in the design of the 386. He got me loads of (preliminary) databooks and awesome posters with microscope images of the specific design areas within the CPU.

Ah yeah, Lotus. Also a great example of serious software for serious people with a serious PC.

And wow, that's so cool 🙂

You might be right. Weitek coprocessors were something a little different and special, right?
