It really was part of the aesthetics in the 80s. I had a gorgeous red cassette player from Sanyo that had text and lines drawn all over it.
There are a few Casios that have cleaner designs.
I don't agree this is exclusive to the 80s. We kept getting this shit plastered onto everything until well into the 2000s.
The Gen Z obsession with Frutiger design wouldn't be the same without the matching typography.
My favorite is the (partly analog) PRW-7000FC-1JF, as seen on https://cdn11.bigcommerce.com/s-e31c8/images/stencil/1280x12...
