[Coco] Newb OS9 and Coco SDC questions

[eebuckeye]

A few more questions please..

 

How do I use OS9 with my Coco SDC?  Just download a disk image? Where can I
download?

 

How do I run games that use multiple disks with my Coco SDC?

 

Is there an easier/quicker way to use disks other than to mount in a drive
then load a file?  Maybe a disk image selector program?

 

What exactly is F1 + reset doing on a Coco3?

 

Sorry for the separate message.. I could not figure out how to reply to an
existing message.

 

Thank you!
