Can you tell me where the batteries are supposed to be, on which board?
I disassembled the machine, extracted the 4 motherboards, I did not
see any batteries anywhere.
If they are externalized, maybe I removed them a long time ago in the
idea of replacing them, but I have not yet found where they were
connected in that case.
I don't know there are batteries, but the device had a lot of
configurations which were retained by some means. 1999 was a bit early
for eeproms that didn't have battery backup of some sort.
If there are no batteries visible, or large super caps which can back up
memory content, that is a good thing.
There may also be Dallas modules in the thing or similar which integrate
batteries. The components will usually have had a 5 to 10 year
lifespan, and probably won't work so well across power cycles.
thanks

I do hope you get it going. If you feel qualified, one thing I'd
also look for are packs with batteries to hold information that may
have decayed. That sometimes can cause what you described. since
the system may have been left since 1999, the batteries may have gone
onto corrosion and you may have a bit of fixing to do for that.
