The Mini 6809

This is my Mini6809 computer. It includes:

• MC6809 Processor
• 32K Bytes RAM
• 32512 Bytes ROM
  That's 32K - 256 Bytes for I/O space
• MC6821 PIA
• MC6850 UART

Check out the Schematic in PDF format.

I communicate with the board using a FTDI Basic Breakout by SparkFun.
That's the little red board in the upper right corner.
