This is a utility developed by Thorsten Wallgren for 
use of ACAD R10 (and possibly other versions) on the 
HP200LX.  I have included a sample batch file that I 
use to load it.  You must load EM87 with R10; ACAD 
R2.6 doesn't require an FPU, so it will load without
the pseudo-math coprocessor and is supposed to run 
faster therefore.

You may have to leave the HP Program Manager to get
enough RAM to run ACAD.  Press MENU, then "A", then 
"T".

Alternately, you can go into SYSTEM in Program Manager, 
then press F5, tab to Advanced, hit <ENTER>, then tab 
down to DOS and increase the value to 384K

After you exit the ACAD graphics screen, the LX's 
screen will display strange characters. Press"0"
then "Y"(the normal keystrokes to return to DOS)
and the batch file will return you to Program 
Manager.  If you edit the batch file to delete 
the "200" line, you will return to a DOS prompt.

This batch file makes it possible to run ACAD R10 on 
HP 200LX. In the screen setup, say YES to if you have 
measured the screen and enter width 32.6 and hight 16, 
so you get the right aspect ratio.

c:\util\EM87.COM /L
cd\dwg
dir *.d* /w
pause
LXSTAT M G0
c:\acad\ACAD.EXE
LXSTAT M C0
c:\util\EM87.COM /U
cd\

This batch file makes it possible to load and unload your 
mouse driver. MARK and RELEASE are public domain utilities 
that allow you to load and unload TSRs like mouse drivers. 
You must use a separate RELEASE for each TSR, and each 
iteration of RELEASE will unload the TSR last MARKed.

@echo off
mark
mouse
<path>acad
release

This batch file combines the above two batch files to load 
the mouse driver before AutoCad starts, then unloads it after 
AutoCad finishes. You will have to further edit them to 
conform to your own system configuration

@echo off
<path>EM87.COM /L
mark
mouse
LXSTAT M G0
<path>ACAD.EXE
LXSTAT M C0
<path>EM87.COM /U
release
cd\
200
