Largest small system emulator
This entry weighs in at a magical 4043 bytes (8086 nibbles, 28,301 bits). It manages to implement most of the hardware in a 1980’s era IBM-PC using a few hundred fewer bits than the total number of transistors used to implement the original 8086 CPU.

"The author hereby presents, for the delectation (?) of the judges, a portable PC emulator/VM written specifically for the IOCCC which runs DOS, Windows 3.0, Excel, MS Flight Simulator, AutoCAD, Lotus 1-2-3 …
In just 4043 bytes of C source, you get a complete mid-late 1980s-era IBM-compatible PC"
