Simon says “hello world”

Last few weeks, I have been learning vhdl to port Simon6809 and Simon6809Turbo to altera fpga board, de1.

Here is the first run of the 6809 processor and simon6809 monitor code.

I borrowed the cpu from John Kent's website.

I'm not going to release the code yet because it is my first real vhdl coding.  so i don't want to embarrass myself.

One thing I realized is regular uart is WAAY slower than ftdi.
