 I highly recommend checking out another open-source x86 emulation
 project that includes vga support, "v86" ([demo][6] / [source][7]).
 There's yet another open-source 386-style emulator in javascript

+Finally, the [Angel][8] emulator ([source][9]) shows off the elegant
+open-ISA 64bit [RISC-V][10] architecture that is being brought to
+silicon by the [lowrisc][11] team.  This is by far the cleanest
+architecture for studying general low-level hardware and operating
