The MCU chip has a DS0, DS1, and some kind of clock line that goes to a PAL
chip.  The PAL converts the serial data into a parallel I/O line.
The book says ,plug in yer 25 wire cable between yer IBM pc and
the HC16 Evaluation board and run....

I don't have an IBM pee cee.  I've got a Commodore Amiga which uses
a MOTOROLA 68030 micro.  I think I can come up with an assembler, or
at least get my files assembled.  I would like to talk to the evaluation
board via my Amiga.

Here is the question......
Does anyone know the parallel port protocol used?
The PAL appears to convert the 17 bit command words as documented by the
CPU16 manual into a 'centronics' parallel port format.  The PAL connects
to 7 of the 8 data lines (The high order line is Not Connected?) the
Ack line, and the busy line.  The question is,  
are all 7 bits used, taking turns sending and receiving?
Are some used to send and others used to receive?
How is the handshaking done?  Do I gotta hook a logic probe just to
find out how the data gets to and fro?

I'm ready to start writting code on my Amiga but need some protocol first.

Email would be fine.
