With #x86 real mode's very odd memory segmentation thing, I wonder if it's even possible to compile #Rust code for it.

Like, does Rust pointer arithmetic even work when pointers are not simple addresses but segment:offset tuples? Because the Rust standard library uses pointer arithmetic aplenty if I'm not mistaken.

There are ways to compile Rust code for #MSDOS, but they require a 386 and work by switching the CPU into 32-bit mode and turning off segmentation.

🌘 Solaris 2.1 for x86：Sun Microsystems 進軍 PC 市場的初次嘗試
➤ 回顧 Sun Microsystems 早期進軍個人電腦市場的作業系統
✤ https://www.os2museum.com/wp/pc-unix-history/solaris-2-1-for-x86/
本文回顧了 Sun Microsystems 於 1993 年夏天發布的 Solaris 2.1 for x86 作業系統。儘管這並非 Sun 首款 x86 系統，卻是其首度嘗試進軍標準 PC 市場。Solaris 2.1 結合了 System V Release 4 (SVR4) 與 BSD 的介面，並為 XENIX 應用程式提供相容性支援。該系統透過 CD-ROM 發行，並需要一張開機軟碟，由於當時可開機 CD-ROM 尚未標準化。安裝方式可選擇網路安裝或僅支援 SCSI CD-ROM 控制器，但可安裝於 ATA 硬碟。Solaris 2.1 採用先進的動態載入式核心模組，類似當時的 Windows

Ah yes, because nothing screams "cutting-edge 2017 technology" like dusting off your ancient #x86 and installing #Solaris 2.1! 😂 In a world where even your toaster runs #Linux, let's all raise a glass to this fossilized OS revival that nobody asked for. 🦖✨

V86 is an x86 emulator that runs in the browser. It supports a selection of preconfigured historical and current operating systems, including a few rarely emulated ones such as Windows CE, and you can upload your own operating system image.

V86 is similar to the popular PCjs.

A nice account of how #Intel spent far too much time & money with #HP on the doomed #Itanium 64-bit #CPU, only to be beaten by #AMD with #Athlon (with help from #Microsoft):

I'm considering trying out a #RadxaX4 for my #NeXTcube mini for a native #OPENSTEP 4.2 installation. Since it's #x86 #Intel hardware (N100), that should be possible, right? 🤔
