Another alternative to disk edtasm is patched edtasm (cart version converted to disk). I'm pretty sure it works with RSDOS disk basic... maybe not ??
I remember having to use it instead of regular disk version for some reason.

Disk EDTASM loads its own version of DOS into memory and bypasses the ROM 
code, so this is likely why it doesn't work. I can't remember the name of it 
offhand, but if you dump the BIN file you'll see the name in there
