[Coco] [Color Computer] Creating a DSK file on a real coco..

The extension .os9 should have worked. Since it did not, there is doubt 
that the image file is good. Do you have a Windows program that will do 
a raw read of files and display the content as dEd does under OS-9? If 
you do, you should look at the testing.os9 image to verify that it looks 
like an OS-9 disk.

Actually there are 3 things to check. 1) Check the file created on your 
Coco using dEd. It should be the same as dEd sees on the real disk. 2) 
Make sure that the data transfer process from the Coco to the PC worked 
without garbling the contents of the file. 3) Check the file contents on 
the PC with a raw file editor.

To expand on point #2, I use the OS-9 program OSTerm, an RS-232 pak, and 
HyperTerminal to transfer files between my OS-9 coco and Windows PC. The 
Coco transfer rate is set to 19200 and Batch y-modem format is used. 
HyperTerminal is set for 19200, VT100, y-modem transfers. Make sure your 
settings are compatable between Coco and PC in similar fashion.
