Jim - 

Haven't tried those myself yet, but I did (with Kent Meyers) author
the patch for the Level I Version 2.00.00 LOGIN that was published in
the 'Inside Level II' book by Kevin Darling. The main problem is that
user ID is set in level 1 by getting into the system's/your process
descriptor and hand-stuffing the USERID in there. Under level II, you
can't get at your process descriptor (at least not this way) and thus
you end up corrupting your *own* data memory (Login's). The patch
simply overwrote the section of code that did the manual-stuffing and
changed it to a f$susr call (set user ID - a user mode system call
available only in Level II). The other changes were cosmetic (altering
the login banner, etc.). Note - these patches were specifically
written for the Login found on the 2.00.00 master disk (Level I).
Login was different in the earlier releases, on each one in fact.
TSmon should work right off the level I disk, but it forks the Login,
which must be modified. If Tandy distributed LI Login to LII users
they should be shot.

P.S. Need you to get in touch with me re: UG when you get a chance.
