Most modules are DC coupled which avoids the problem with the 20 year
lifespan of electrolytics. I have seen 36 year old Buchla modules which
still function perfectly and are under original calibration. It is entirely
possible that analog modules which do not use electrolytic interstage
capacitors will be working and in calibration in 2100. Seriously.

Early digital devices are much more of a problem. Find a 2708 any more. Plus
one bad bit in a OS PROM turns it into a door stop. But there may be ESQ-1s
and the like still working fine in 2100.
