[Coco] OS-9 DS floppy config - SUCCESS!

Tue Aug 10 22:22:26 EDT 2010

Well dude I haven't read the manual.  All I know is I applied the "patch" to CCDISK, set the STP to 03 to match what the NitrOS9 STP setting was, and it ruined the stepping rate.  It SUCKED.  I put it back to 00 and it was quiet and quick like I'm used to 6ms being in NitrOS9, DECB, etc.

Hi Chad,

the "standard" OS9 level 1 disk device descriptor has its stepping rate at 
offset $14. The options are 0=30ms, 1=20ms,2=12ms,3=6ms.

Pages 39 and 40 of the OS9 Technical Information manual refers.

Hope that helps
