Ed -- are you referring here to IC's mechanism for linking to assembly
language files, the "IC Binary" interface?
It's really not too hard to use, and allows users to create assembly
language programs that are callable from IC using the C function call
syntax. The assembly language module can create globals that are
accessible from C, and the asm routine can be passed and return an
integer value to/from C.

Ronan -- is the ACIA an extra serial port that BUFFALO uses to
communicate with the host? It shouldn't be too hard to tell it to use
the built-in 6811 SCI rather than this port. Getting BUFFALO running
on the HB seems like a good idea -- if this is the only real obstacle,
we're not far away.

| I am planning to use the handyboard with my freshmen in Fall. In addition to the obvious benefits of demonstrating embedded systems, hardware, and robotics, I am interested in using the handyboard as a platform for introducing students to computer (...)
