THe answer to your question is as follows:

Yes, you have 64K on your CoCo 1.  However, BASIC and RS-DOS cannot
access the entire 64K at once, since the ROMs are mapped into the upper
32K whenever you're in BASIC.  TSEDIT (apparently, since I've never used
it under RS-DOS) is able to use the entire 64K by switching out the ROMs
and using its own routines (rather than using the ROM routines like SCRIPSIT
does).  Level 1 OS-9 is sort of hard to find, but it still can be bought,
especially if your local Rat Shack has a tent sale.  You shouldn't pay any
more than about $20 for it (the going rate the last time I saw it).
