Hexbear Proposals chapo.chat matrix room.

This will be a place for site proposals and discussion before implementation on the site.
Every proposal will also be mirrored into a pinned post on the hexbear community.

Any other ideas for helping to integrate the two spaces are welcome to be commented here or messaged to me directly.

Within Hexbear Proposals you can see the history of all site proposals and react to them, indicating a vote for or against a proposal.

Sending messages will be restricted to verified and active hexbear accounts older than 1 month with their matrix id in their hexbear user profile.

All top level messages within the channel must be a Proposals (idea for changing the site), Feedback (regarding non-technical aspects of the site, for technical please use https://hexbear.net/c/feedback), or Appeals (regarding admin/moderator actions).

Discussion regarding these will be within nested threads under the post.

To gain matrix verification, all you need to do is navigate to my hexbear userprofile and click the send a secure private message including your hexbear username.

Happy to have increased your computer history knowledge! meow-floppy
If you mostly touch modern computers, it's not surprising that you didn't know, because Intel's x87 floating-point co-processor is mostly a thing of the past. Since the i486, the floating-point has been integrated into the CPU rather than being a separate chip. You can still issue x87 floating-point instructions to the i486, or even to a modern Intel CPU, though! Nowadays, if you want floating-point stuff, you (or the compiler that compiles your program) will probably use SSE instructions instead. But I heard that some applications where the precision is very important still use x87 because it internally represents the numbers as 80 bit instead of 64 bit.

I forget; was it the 80387 or the 80487 that was just a full-blown DX (as in, FPU included on the die) version of its 80_86SX counterpart with only subtle differences in the pinout so it could disable the onboard main/SX processor socket?

Edit: Found it! It was the i487 SX:
