…мы вычисляли как могли.

Basically, Flea86 is a fully-custom x86 emulator, originally written by me to run a high-speed version of Intel's 8051 microcontroller (specifically Appotech's AX-2005 System-on-chip, which contains an 8051 core). I also designed the PCB artwork (pictured above), around AX-2005 SoC as a hardware platform to run my x86 emulation software on.

P.S. Для тех, кто не понял. Он сделал эмулятор шестнадцатибитной ЭВМ на восьмибитном микроконтроллере (точнее SoC).
