From the project
Tiny IBM PC compatible machine with 386 CPU, integrated VGA and sound.
To upload firmware you need USB-UART adapter with 3.3V signal levels. Connect GND, RX and TX lines to esp header located on main PCB at left, install BOOT/GND jumper and follow any ESP8266 firmware update guide that is available on the internet.
Top PCB: Rev.A - first release. Please note the errata; Rev.A1 - fixed all rev.A issues; added switch for VGA BIOS variant select; removed VGA-disable switch; added EEPROM for ES1868.
