Call MISOSYS (1-800-misosys) and buy LS-DOS 6.3.1.  Model 4 TRSDOS 6
is LS-DOS with the Radio Shack name (as PC-DOS is to MS-DOS).  This
is the latest version (released last year).  I believe it is $39.

If you want TRSDOS 1.3, you will have to go to Radio Shack.  I would
suggest getting LDOS 5.3.1 from MISOSYS.  It works almost exactly like
LS-DOS, but in Model 3 mode.  It blows TRSDOS 1.3 out of the water.
(some Model 3 software will only run under TRSDOS 1.3, though).

I believe Computer News 80 has Montezuma Micro CPM 2.2.  This is your
best bet.  Radio Shack CPM was based on CPM version 3.0.  I've heard
a lot of complaints about the Radio Shack port of it (never used it myself).
