[Coco] Frustrated in Seattle

[George Ramsower]

Nope! The 5.25 won't work. I expect the heads are dirty. I'll have to make a 
cleaning disk tomorrow and see if that helps. All my 5.25 disks are as old 
as the hills.
I did find some cool old stuff I forgot I had though.

FWIW. The way I transferred OS9 disks to 3.5 floppies is simply do a backup 
from the 5.25 to the 3.5 in RS-basic. Then you have an exact copy of the 
5.25 on a 3.5.
 Of couse, you have to DSKINI the target disk. I set mine up with the 3.5 as 
drive 0 and the 5.25 as drive 1. After you make the backup, you can boot 
from the 3.5 in drive 0 and from there.........
 Then you start making changes to the system and create a new boot disk to 
reflect these changes..
 Whew! It's been a long time since I went through this... converting to 3.5 
disks and making 720k disks.

 It's been so long, someone may be able to help on this subject.

 So don't worry about having the 5.25 as D0. Make the backups and then it 
should work. Besides, those old disks NEED to be backed up!

 Whatever it is you want to boot from, just back it up to the 3.5 and it 
will boot, providing you backup the 5.25 on drive 1 to the 3.5 on drive 0 
after you DSKINI the 3.5. Now this will not work if the source disk is 
double sided and/or more than 35 tracks. All the NORMAL OS-9 disks provide 
by the vendors were compatible with a stock, single sided, 35 track Tandy 
Color Computer systems. So there shouldn't be a problem doing this 
conversion.
