| (...) These pins form the "Serial Peripheral Interface" (SPI) circuit, which can be used to link 6811s with a 1 megabaud network connection. They also are individually addressable I/O pins.

Typically, if you are powering your system from the SIB, this indicates some kind of board short. I would remomve all (...) (28 years ago, 19-Oct-96, to lugnet.robotics.handyboard)

| | using Buffalo with the HB
|
| Ronan -- I don't think it's the LCD per se that is causing problems, but rather the fact that the HB runs the 6811 in special mode. The main effect of this is that the interrupt vectors, including the reset vector, live at $bfc0 to $bfff rather than (...) (28 years ago, 1-Oct-96, to lugnet.robotics.handyboard)

| | Re: IC on Tcomp?
|
| 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)
