The Dodo is yet another homebrew 6502 single board computer. The goal is to ultimately create a portable game system out of it. The processor is the WDC 65C02, and the support chips are a 65C22 VIA, 6551 ACIA, 32k EEPROM, and a 32K SRAM. The address space design cuts the RAM in half to 16K, but the tradeoff is a very simple/flexible IO addressing scheme. The display is the 2.42″ 128×64 OLED from Adafruit running in 6800 8-bit bus mode. For software I am using the cc65 suite of development tools. I will consider this project done when it is on a PCB, mounted in a 3D printed enclosure with a gamepad built in, and I have written a game fun enough that my 4 year old digs it.
