[Coco] 3.5 inch floppy drive

[James C. Hrubik, Sr.]

Just remember that your controller may not handle HD drives properly.  
The 3.5 drives are electrically compatible with the 5.25 DD drives, 
BUT...  if you format a 3.5 disk on the PC, it has to be DD formatted 
(720K), not HD (1.4M) formatted.  Then you can read it on the CoCo with 
the PCDos utility under OS9.  And I _think_ (rusty, here <G>) you can 
access it as a normal 40 track SSDD drive under RSDOS.  Make sure you 
have the drive jumpered properly (D0 or D1).
