Google Motorola "Works in a drawer" and you see an image where the drawer is pulled out.
The main electronics was on a drawer behind the knobs and speaker on a slide out for service. Supposedly to help make service easier since the back of the set didn't need to be removed. You simply turned a locking device, and pulled the drawer out to get at all the good stuff.
Ah, found it. That looks safe
