You may also notice that the Model 100 has support for the following devices:
LCD:, CRT:, CAS:, COM:, WAND:, LPT:, MDM:, and RAM:.  CRT: and WAND: are not
documented in the owner's manual.  If you get a copy of "Inside the Model 100"
by Carl Oppedahl (c) 1985, you will see a brief write-up of these otherwise
undocumented BASIC keywords.  I haven't seen any programs that use them, but
I'm not the last word on this.  :-) Take a look at the Covington memory maps,
available FREE on this BBS from the main menu in the technical reference
area--LOF has a RAM vector at FB28H, LOC has a RAM vector at FB2AH, DSKI$ has a
RAM vector at FB2EH, and DSKO$ has a RAM vector at FB30H.  The addresses for
device control RAM hooks for WAND and CRT are also given.  Presumably, one
could POKE values in RAM to redirect the commands to execute your own bit of
machine language programs.
