BusRaider by Rob Dobson

Memory Mapped Graphics and Single-Step Debugging for Retro Computer

BusRaider is an add-on circuit board for the RC2014 retro computer. It uses a Raspberry Pi Zero and an ESP32 to snoop on the bus of a host vintage 8 bit CPU and provide things like a memory mapped display, WiFi connection, keyboard and single-step debugging

More information is in the blog post https://robdobson.com/2018/08/trs80-galaxy-invasion-on-rc2014/ and https://robdobson.com/2018/08/trs80-galaxy-invasion-on-rc2014/

How to run

  1. Format an SD-card with FAT32 filesystem.
  2. Copy PiSw/bin/kernel.img to the root of the SD card along with the files config.txt, start.elf and bootcode.bin that are commonly distributed with the Raspberry Pi
  3. Insert the card and reboot the Pi on the Bus Raider PCB

As soon as your BusRaider is turned on, the message "RC2014 Bus Raider V2.x.xxx" should be displayed on the HDMI video stream along with a display area for the Retro computer.
