[time-nuts] TruePosition GPS Receiver firmware

One of my TruePosition GPSDOs fried a chip in the power supply when the wall wart that was powering it failed and started putting out 23V. It apparently ran for a while at that voltage before violently letting the magic smoke out.

If somebody can read a Spansion S29JL032H90TFI12? chip (some of the last digits are hard to read), I can pull it off the board and send it to you.   Searching the dump should reveal strings that show more of what the command set is.  I believe the chip is a 48 pin TSOP.   I don't have the proper adapter for my Data I/O machines.
