[Coco] Booting OS9 on my CoCo 3

[Dave Philipsen]

In fact, that may be the solution to all of my problems.  The only 
reason I'm trying to boot from a floppy is to take a look at all of my 
old disks to see if there's anything I want from way back.  I'm 
especially interested in seeing if I still have the original source code 
for SuperComm.  The source that's floating around now was Randy Wilson's 
disassembly and is missing a lot of good comments.  There are also some 
other projects that I had worked on that would be fun to resurrect...
