| Does this mean that other operating systems WILL NOT RUN ?.

     What this means is that H.I Tech does not currently sell software to
configure the XLR8er for high speed operation under any other operating
systems other than the ones mentioned above.

*** EXCEPTION: ***  ==> TRSDOS 1.3 for the Model III

This OS DOES NOT run and WILL NOT run on the XLR8er.  The reason for this is
that 1.3 has one or more illegal Z80 instructions in it that the 64180 traps.
We haven't done much research into this problem since practically no one uses
TRSDOS 1.3.  (Does this cause anyone out there trauma?)  It is known that
DOSPLUS 3.4 (for M3) runs with the XLR8er although there has been no software
written for it that I know of.  I seems to recall that someone was going to
work on patches for M4 NEWDOS, though.  I'll check on it.  Thanks for bringing
up this question, Mike.  I forgot to mention anything about it in my last
article.
