  When I first ran this, I received an error 216. DOH! I should have seen 
that one coming..

 I don't know if it makes any difference how the file is created, but I used 
"display >filename" and then "dump filename". It appeared to be an empty 
 Then I ran the B09 program again and it appeared to work. I got the file, 
transferred it to this XP box, ran MESS and attempted to boot from it and I 
got the familiar "OK" prompt.

  Next I booted with another image, mounted this file as /d1 and tried to 
look at it....
 Error 249

 So I checked the Dmode on the /d1 driver and it was good.
 Then I did "attr /d1" and got no report.
 Then I did "attr /d1 d-ewrewr" and looked at it again and there still was 
no report.

 Then I tried to format this file and after it did the write, it came back 
and errored every sector.

 Any suggestions?

 BTW... At 2400 baud, using xmodem it took 57:35 to download to this XP box. 
I'm going to play with higher baud rates and different protocols to see what 
would be the fastest way to do this sort of thing. I don't transfer much 
between the coco and this XP box, I just use hyperterm to operate the coco 
because the coco is in a room that does not lend itself to a sit down 
session. Keyboard familiarity and comfort is good. OS9 is perfect for this
