By the Late 90s…

…and early 00's, Sony had their Discman shit down to an art. It's really too bad the whole product line died only a couple years later with the advent of the iPod because it really is amazing technology.

My naked D-171 that I bought new 1998.

Yeah, the Discman cases went all plastic, but everything was now consolidated onto a single circuit board, a definite improvement in terms of serviceability. Remove four screws from the bottom and the top/tray pops right off…unlike my beloved D-10 which has two double-sided circuit boards linked by a ribbon cable, multiple wire connects,  and is much more complicated:

Or this, my original D-7 from 1986 with a belt-drive spindle motor. And look at that laser transport!

Still a feat of miniaturization and engineering considering that full-size CD decks only came on the scene a few years earlier.

Remember…obsessed.
