MICRODEM is a microcomputer mapping program written by
Professor Peter Guth of the Naval Academy.
To get the program:
BDE (Borland database engine) install. If you do not have the BDE
and are running the 32 bit version of the program, 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 (~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 first time you attempt to access the help file, the program
will ask permission to download it.
MICRODEM install, 32 bit (~20
MB). The 32 bit version will no longer be updated, and this
is not recommended. You should upgrade your OS and run the 64 bit
- 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 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,
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 on the file in the File Manager, pick option at bottom right
64 Bit MICRODEM EXE (16MB). This
will be called MICRODEM.exe, and is the preferred version of the program to
run. The 64 bit version will be faster, and
allow access to larger data sets. Requires a "recent" complete install
and will be more current than the version in the complete install.
Does not require the Borland Database Engine. Use the "Save file
as" or "Save target as" and
Place in the MICRODEM directory (c:\microdem).

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
