[Coco] continuing to eliminate errors in the nitros9 build

[Bob Devries]

Hi Gene,

I have eliminated the error 248 problem with the d64 and tano single-sided 
disks. It may be unconventional, but it works:

in file /nitros9/level1/d64/makefile

under $(DSK180K_1):

change:

$(OS9FORMAT_SS40) -e -dr -q $@ -n"NitrOS-9/6809/Dragon Level 1 Disk1"

to:

$(OS9FORMAT_SS40) -sa=2 -e -dr -q $@ -n"NitrOS-9/6809/Dragon Level 1 Disk1"

I know that the lesser SAS could cause fragmentation, but this is not 
applied to the device descriptor, just the disk. It will likely cause 
problems for anyone using DSAVE to make a copy of the files onto another 
disk; better to use BACKUP.

Comments?
