I'm sorry but I no longer have the customized DOS APRS files for the Southeast. They were list in many server migrations
Download the latest version here (but look just above here for a customized plug 'n' play local versions and for help in getting started)
Your FTP client should open and if prompted, use anonymous for the user name and a blank for the password
APRS-PLUS
APRS-Plus. Works with DeLorme's Street Atlas 4, 5, 6, 7, or 8.
The Original APRS for DOS
Look for a file named something like APRSxxx, where xxx is a number. Last known version was APRS848.ZIP
WinAPRS. Works with Windows 98, 95 and 3.1 and can use Precision Mapping 3. (but nothing later)
Look for a file named waprsxxx where xxx is a number. Get the highest number. Last known was waprs246.zip
APRS for the Apple Macintosh only.
I have no idea what file you need, but if you use a Mac, you should know ;-)
JavAPRS. Not for the faint hearted
You may just want to browse all of the TAPR APRSSIG files.
