It's Just A PC | S01E34 | An NES ROM Monitor - part 2/2?

I'm going to try and actually start doing some streaming, and about what you may ask? Ever notice how a video game console is basically just a normal computer with missing parts? For some reason I have an urge to stick those parts back on.

Yesterday: Got a minimal monitor running on the NES with our previously written I/O routines. Unfortunately it doesn't have a command to print any less than 128 memory locations at a time.

Today: Short and sweet, hopefully. Figure out how to get the monitor to just print a single byte at a time so we can read from specific registers on the floppy controller and really play around with the thing
