Word meaning: "containing no electronic components"

Question

I want to find a single academic-sounding word that means: "containing no electric parts" or "containing no electronic components"

I originally thought "analog" would work here, but after double checking the definition, I have reconsidered.

I can easily think of a few examples, but the naming convention does not seem universal. Take:

electric drill > hand drill

mower > push mower (antique)

In contrast to the above, I want a word that can be applied to any object.

Here is a sentence I had in mind:

Automobiles manufactured before the 1980's are typically _________.

Answer 1

free of electronics

electronics-free

mechanical

hand

However, none of these work with your car example

Automobiles manufactured before the 1980's are typically _________.

because cars included electric starters since the '20s.

It seems you are referring to computers or semiconductors, so you could say

computer-free

semiconductor-free
