8031 Single Board Computer

SBC I made for learning MCS-51 assembly.


This is a single board computer utilizing the 8031 microcontroller. The 8031 is the ROMless version of the 8051. This allows me to modify the program running on the 8031 using an attached EPROM. This SBC easilly connects to a breadboard.
