You have a number of options. Don't reinvent the wheel. If you have 
access to "The Rainbow", Sept. 1983, there is an article by Roger 
Schrag, "Superpatch for EDTASM". It shows how to save and patch the 
EDTASM ROM pak converting it to a disk program.

There are many ways to transfer a .dsk image on a PC to a real floppy. 
What you use depends on whether your PC OS is based on DOS or is WinNT 
or later.
For DOS based systems, any emulator that reads real disks can create 
floppies. The utilities that come with the JVC emulator can also be used.
For WinNT XP or Vista systems, programs like Omniflop and Cocodisk can 
be used to create floppies.
If you have a terminal program on your Coco (Ultimaterm for Basic or an 
OS-9 package) you can transfer files to the Coco over a null-modem cable 
using Hyperterminal or a similar PC program.
