At one time I thought I had the answer to this but I've misplaced my notes and don't want to possibly damage
a workable radio to figure this out again.
I've got a very interesting 7100 radio board that doesn't power up and may be a FIPS death case, but
I'm not SURE of that yet. M/A-Com doesn't release any documentation of what happens to a FIPS dead
radio so I'm kind of working blind here. And then again, maybe it's not even a FIPS-enabled radio
and just has a bad regulator. Not sure.
I don't care about any encryption hardware on this radio. What I want is to isolate one specific bit of
information, and a second if possible.
1: Which EPROM chip stores the feature encryption string? This radio's ESN is still present, and I would
like to salvage that and the feature string for use in another radio.
2: Which chip is the radio personality stored in? If I can transfer that to any working radio, I can
read out the personality which I suspect may be sort of interesting.
The sad thing is, I once knew which chips stored this info but the last time I tried to reproduce the experiment, it didn't work. Which means I probably forgot which chips are the critical ones.
If I know which ones to swap out, I will be successful. There's no chip on these radios I can't change
out with near 100 percent success rates.
