Thank you both. I did another Concorde flight from Tampa (KTPA) to Charle DeGaulle (LFPG) and took screenshots. As expected, all three warning lights came on at the same time 1,2,3. Codes 102 and 131 again appeared. I can understand the 131 code now if "vololiberista" is correct that 131=GS greater than 910 knots. "102" kinda makes sense that I needed to check NAV Data since I was in the Oceanic portion of flight with no way to do a DME update. Here are the shots.

As you can see I was using INS 1 for NAV. I do not understand the reason for switching the MSU switch to "ATT" or turning the unit off. I then lose that MSU/CDU for the rest of the flight.
Despite the warning I made an uneventful trip to LFPG updating the lower waypoints to new ones as I was flying from current WP 8 to current WP 9 in each CDU using the "REMOTE" buttons.
As for the warning light, is there any way to extinguish that until I get back in range of a VOR so I can do DME updating?
As to "131" code. How did Concorde handle those codes on the real CIV-A, since they too flew at speeds in excess of 910 KT groundspeed (I was at M2.02 for most of the flight)?
