[Coco] Machine Code

[Dave Philipsen]

Actually, understanding 'machine code' can be very beneficial.  If 
you're going to write code in assembler, why not understand exactly 
what's going on under the hood?  I can't tell you how many times I've 
just done a quick dump of memory and seen certain combinations like "7E 
80 00" or "1A 50" or "20 8D" or "12" or "39" and recognized what was 
happening even without using a disassembler.  It's true that virtually 
no one writes in "native machine code" but I have, on many occasions, 
patched code for purposes of experimentation/testing with machine code.  
And, in some very rare cases where I was working from a monitor that did 
not include an assembler or disassembler on a platform (usually an 
embedded controller) where it wasn't necessarily easy import and test 
new code, I have actually written a bit of "machine code" or 
cross-assembled on another machine and manually entered the code 
byte-by-byte on the target machine.

And I do agree that starting out with EDTASM+ and a good tutorial is the 
best...
