Hi Group,

Well, I'm cooking up this board at the moment.  I have all the hardware
figured out to run like the original CPU boards.
I need to do a little more testing of the hardware, then I'll proceed to
building the boards.
The Memory, I/O, UARTs and SPI interface to the SD card appear to all be
working.
8K chunks of memory can become either ROM, RAM or mapped off the board.


I'm interested in one.

Rob.
