I think "computerized" may be a better way to look at it.
The first sets using digital tuning such as Magnavox
"star system" had hi parts count not a single does it all
micro. The star assy was big & probably had as many parts
as the rest of the set. Things just evolved from there.
In the late 70's more things got down to one or two IC's
on a 6x6" board doing everything & more.
Earlier sets with varactor tuners used mechanical
switching (most) or electronic ( Sanyo, Toshiba prob others ).
It switched between pots & band switches for each preset.
For remote just add a motor or more electronics.
The GE you spoke of was a real mongrel. Digital tuning
done mechanically as I remember. I think it was only
used on the hellish EC chassis & maybe AA-AB-AC.
It may have also been a normal set-up. Memory very foggy
on this, it was a rare bird.
