There are two possibilities.

DATOM Engineering offers a product called Contest Voice Blaster 
(CVB).  This is a TSR which runs on top of any DOS program, and can turn a 
Creative Labs Sound Blaster into a contest voice keyer compatible with 
NA.  CVB requires a real SoundBlaster card, along with a driver file called 
CT-VOICE.DRV which is provided by Creative Labs.  The CVB documentation 
shows a simple interface (a couple of small relays and some transistors and 
resistors) which routes the audio signals to/from the radio to complete the 
package.  CVB is available from Radio Bookstore 800 457-7373.

Kevin, W9CF wrote a driver that makes a sound card look like a K1EA DVP for 
voice message playback.  The program is freeware - look at 
http://fermi.la.asu.edu/w9cf.  He only claims it will work with TR-Log 
(which is what he uses), but in looking at his FAQ on the subject but I see 
no issues which would prevent it from working with NA.  I have not tried 
this program, but it could be very slick.  In a note dated 8/2000, UA9CDC 
reports it works perfectly with TRLog.

Since you have a older machine running DOS, this might be easy to set up.
