MICRODEM is a microcomputer mapping program written by
Professor Peter Guth of the Naval Academy. The program requires a 32 bit version
of Windows such as XP and will run on 64 bit Windows in 32 bit mode.
To get the program:
BDE (Borland database engine) install. If you do not have the BDE, you
should download and install before running MICRODEM. The program can
automate this, but will probably not do it elegantly and will give you a
number of error messages which you can avoid by installing the BDE first.
We are working to eliminate the use of the BDE, at which point this step
Complete MICRODEM install (~20
MB) . This no
longer includes the help file. You can download it separately, or use
the update function inside the program (on the help menu). The first time you attempt to access the help file, the program
will ask permission to download it. The program will ask to
download the BDE (Borland Database Engine) if it is not on your system; if
it does, you will see error messages as the program will not close cleanly
the first time.
- The best way to update the program EXE depends on
your OS, the security imposed by your network, and whether you have admin
rights. In order of ease of use, these are:
- Option on the Files, Tools menu inside
will close the program and update the executable, and
restart the program.
- Use update program in
the MICRODEM directory (md_update**.exe), which will download the new EXE and
start it. MICRODEM must be closed for this to work,
and virus checkers do not like this option (they are wrong
about any problems, but most don't care much about false
- Use the browser downloads
- The best way to get or update the help file (65 MB) is to
use the option on the Files, Tools menu, or on the help menu inside
MICRODEM. Insure the help file is closed first. This is currently working
reliably as far as we know. If it fails, get
MICRODEM help file here. Use
the "Save file as" or "Save target as",
the MICRODEM directory (c:\microdem),
and insure the browser does not append (1) or (n) to the file name.
You are likely going to have to change the file properties to
unblock it (right click, pick option at bottom right).
New EXE (10 MB). Requires
a "recent" complete install and will be more current than the
version in the complete install. Use the "Save file as" or "Save
target as" and
the MICRODEM directory (c:\microdem).

executable download works, but may rename the file. Watch for (1) or
the file name, and rename back to microdem.exe
- The military icons generator is available as a separate program (1.5 MB)
which allows you to create unit icons and paste them into
your favorite graphics program. An improved version is included in MICRODEM.
Executing the installation program will create
icons on the start menu and two directories:
- c:\microdem. You can put this elsewhere, but if you encounter problems, you were warned
and we will not try to figure out what is wrong.
- c:\MapData\ with subdirectories. You
can put this on another drive, but it must go into the root
directory of its drive.
The program will create a log of program
operations in the file 'microdem_debug_log.txt', in
c:\microdem\logs; the easiest way to get the file is to to open
it from the Help menu while the program is still running.
You must copy this file immediately after encountering an
unexplained crash, because the file is overwritten every
time you run the program. Send the file to me and I can
better determine what caused the problem. The debug log
is not complete, and I may have to add additional
debugging messages to the program and have you repeat the
error and send a new log until we can isolate the
You can get data sets configured to work with MICRODEM. We
are moving the download of data to occur inside the program, which will
automatically put the data sets in the correct locations. See the
You can still get the following data sets:
If you want to perform code archaeology, you can get the
DOS source code from about 1995.
