I just got a handyboard and have been playing with it. I would like to maybe network a couple of miniboards to it for expansion using the SPI. So: 1) how does one drive the SPI, software wise?

Good question. In principle, the answer is yes. The base requirements for running IC are the 6811, 32K ram, and a serial port. In practice, no one has modified the pcode for a "generic" system configuration. One tricky part would be disabling the (...) (28 years ago, 17-Sep-96, to lugnet.robotics.handyboard)
