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.
