I suggest MYDOS; the source is in the public domain, and you can get it
with a mini-assembler (which takes the same source as Atari's AMAC, except
without macros).

I took copies when they were posted here several months ago.  I could
figure out how to repost them if you get desperate.

And now a MYDOS technical question:  How is the mem.sav part of MYDOS
loaded?  Also, is it loaded at boot time, or when you enter "DOS" 
from BASIC?
