Where can find the documentation for working with my SDC in Nitros9? I found SDC listed in /CMDS. But, I don't know the syntax. I don't know how to properly mount and/or change disk images in Nitros9 for use with /d1. I mounted an OS9 disk in drive 1 in DECB. However, OS9/NITROS9 doesn't recognise a disk in the drive. Thanks!
