what's going on? have I missed something?
Gawd it's been a while since I even turn the triac on let alone added
memory...
yes back up params, check you can read them, check against the machine that they are all there, print them out, put a copy in a safe deposit box, get the idea?
Then the diagnostics, can't remember how they're shot out to backup...

Do the same with these.
Also save any programs/offsets
Turn of machine crowbar out the card & hammer in the extra lumps, I don't know with a OM-B but a C has 4 holes, I'm sure these go in the same way around as all the other irrelevant chips.
Then put it back together. There are supposed to be a few vital params you can hand enter ie, the comms params but it never worked for me and I can't remember what they are. So you could be in for an hours work bashing in the numbers....
I seem to remember they stay until change you
memory parameter.
if in doubt swear
