I am the SYSOP of the Nicolet BBS system - NICBUL.  It is a PC-XT frame with
2 Kamerman 10Mbyte hard disks, 2 Teac 1/2 height floppies, AST Mega-Plus
Memory expansion/dual serial port board.  Right now it has the Hercules
Monochrome Graphics card, but I had the regular IBM Monochrome card.  There
that takes care of my system.  I am using it right now with PerSoft VT100
terminal package.

A program should NEVER blow up a part of a computer.  I think you were a
victim of Murphey.

As for the LU.EXE program.  It is NOT for a squeezed (compressed) file.
It is for a library file.  A file that has a .LBR as the extension.  The
squeeze/unsqueeze programs work on files with a Q as the second letter
of the extension, ie. .LQR, .CQM, .EQE or QQQ.   The .QQQ is for when the
original file didn't have an extension.  The most common squeeze program
is SQ182 and the common unsqueeze program is NUSQ110.  Documentation does
exist for the squeezers and the library programs.  I have them on our
board.

Give our board a call, (608) 273-5037  6pm to 8am M-F CST and all day
on weekends.

Someplace in the IBM PC Tech Ref Manual it makes a cryptic comment about
configuring for various monitors. If the CRT ctrlr is not initialized properly,
either from DIP switches or software, it can gen a voltage sufficient to ruin
monitors (at least color).  Therefore, one may surmise that a program that
clobbered the settings for the CRT ctrlr could have similar results, although
one w/o checking voltage levels, I am hesitant to make any stronger statements
than that.

I have, however, witnessed the slow demise of a set of color monitors used by
a certain start-up company that failed to properly configure, although the
process took at least several use-hours to occur.
