 +===== Walking Through The Code =====
 +
 +As I have worked through the NEC PC6001 port I have found many nooks and crannies to explore and decisions about how to my port to the CoCo along the way.
 +
 +The NEC PC-6001 loads the NOSTRO cassette data into the BASIC program memory.
 +
 +The cassette file continues past the last line of tokenized BASIC code, loading Z80 binary machine code and more data into the memory after the lines of BASIC.
 +
 +I've decided to build this table to organize my findings and help complete what's left to port.
