OK, now we have something to work with. Please post (or send to me) your 
standard.bl file. In step3, you are indicating that you attempted to use 
the Tandy Modem modpak module m1.dd and it could not be found (error 
216). I'm not surprised it could not be found as it is not part of the 
release. However, standard.bl has all the Modem modpak entries commented 

Are you saying that you get random errors in Step 3? Have you been 
changing the contents of standard.bl other than rb1773.dr?

If you include modules that were commented out, make sure that the 
modules actually exist on the disk. If they do not, you will need to 
include them from some other source.
