[Coco] Help with dumping various EPROMS

[Ron]

Hello all,

New to the list and recently getting back to using my CoCo after more 
years than I'd like to count...  :)

I opened up one of my Distro Super Controllers and noticed I populated 3 
of the 4 available banks with various EPROMS I had burned a while back.  
These include Extended ADOS3, RGB-DOS & CDOS.  I'd like to dump all of 
these to diskette for backups just in case I would ever want to burn 
additional copies or use them in an emulator (if possible).

I'm still trying to remember how to do this - I know I can do it with a 
SAVEM command, but need to know the address ranges.  These are all 28 
pin EPROMS.

Can anyone assist?

Thanks!

-Ron
