I'll have to check when I get home.  Mine was designed to be installed
in fleet vehicles.  It ONLY does TAIP and would have come with a single
board computer (286 or 386) with two serial ports.  One went to the GPS
and the other went to a radio modem.  The only software I ever used for
the GPS functions was a DOS app written by Trimble.  I still have it
on a 286 laptop somewhere.  It doesn't have maps per se, but it will
generate a chart showing where you have been since the app was started.
It only receives a couple of parallel channels (if that) and almost
never gives me an altitude lock, but even one channel is good enough
for ntp.

I've thought about upgrading to a modern handheld unit, but I keep putting
it off.  I've done a few geocaches with a friend and it's sort of fun.
I can never make up my mind if I want bluetooth, standalone, etc...
