MICRODEM is a microcomputer mapping program written by
Professor Peter Guth of the Naval Academy. The program is freeware;
license is freely give to any user to freely use the program without any
To get the program:
Complete MICRODEM install (~30
MB). This installs the 64 bit version. You can download the
help file separately, or use
the update function inside the program (on the help menu). The
64 bit version will be faster, and allow access to larger data sets. The first time you attempt to access the help file, the program
will ask permission to download it.
- 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. Your current version
will be archived if you wanted to revert to it.
- 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,
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

Place in the MICRODEM directory (c:\microdem).
Browser may rename the file. Watch for (1) or
the file name, and rename back to microdem.exe
For a short time, to support students with older computers, there will be
a 32 bit version of the program. You must do the full install, and
then download the 32 bit EXE, add it to the directory with the 64 bit
EXE. Then run that version. It should be functionally equivalent,
but multi-threading will probably be disabled because it has problems
and it is not worth the effort to track them down.
- 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

DOS source code from about 1995.
