It appears as if the design may have changed somewhere between PSTI and 
Traconex!   The manual I have, and I assume it applies to the receiver I 
just bought (it came with the receiver) is dated March 1, 1992 and 
claims "PROM Version 5.02".   This manual states that Bank 3, Switches 
1-4 are used as follows:
2         3        4
Serial Port Debug (Traconex)            OFF   OFF   OFF   OFF
Pulse at 23:59:59  (Traffic)                OFF   OFF   OFF   ON
Pulse at 03:29:59  (Traffic)                OFF   OFF   ON    OFF
Both Pulses (Traffic)                          OFF   OFF   ON     ON
24 Time zones (Condor Basic)          OFF   ON    OFF   ON
24 Time zones (Condor Expanded)   OFF   ON    OFF   ON

When it synchs up, it displays the year as 04 so it must be doing 
something right.
