And keep in mind, while RGB-DOS could only do 256 disk drives, if it was running in RAM mode on a CoCo 1/2, or on a CoCo 3 which is already in RAM, you could POKE those offset values real-time and access more drives.

I have 416 RS-DOS images on one of my SyQuest SCSI drives. I have a program on DRIVE 0 that let me select which bank I wanted to be in, 0-255 or 0-XXX and on the second bank that DRIVE 0 had the same program. If I had a larger disk I could have had as many as I wanted.
