"The oldest I currently have is a 25 year old C8 that looks and
works great. Many of the others are early to mid 90's units that are
now ten years or older."

I have a 1990 Ultima C11. About 5 years ago the drive circuit died on a
105 dF Texas night. Luckily this mount had an AC synchronous motor so a
simple 12V DC->120V AC @60 Hz inverter can be used to drive the motor
well enough for visual observations (the only observations I do). Total
repair cost $12.

I think, however, the key here was the AC synchronous motor and the
wedge tripod design (only 1 motor running at constant speed).
