I'm not sure about Booster Pack for the m200--if it's not listed in the online
catalogue or in the ForSale section of this BBS, *I'd* doubt it's existence.
:)
 
However, as a computer programmer, I can give you a definite answer vis-a-vis
your query on Model 100 emulation for the m200--it *is* possible; any lack of
one is merely caused by lack of programmer inspiration, time, and incentive.
:)
 
I have, in my past, written several terminal emulators and editors.  The theory
is simple; have a program read the input stream.  If there are no control
characters, echo the input to the output.  If there ARE control characters,
then look up what function should be performed.  :)  For example, on a VT100,
the <ESC>[7m sequence means to begin writing characters in reverse-video.  On a
m100, an emulator would write an <ESC>p (I think; I'm writing this from
memory).  This latter sequence would perform the same function on the Model 100
that the initial sequence would on a VT100.  So the main thing an emulator
writer would do, initially, is compile a table of function sequences, for each
terminal/computer, and then match up which escape sequence does what.  :)  [I
hope I'm clear.]
