This is like "Back to the Future". Or shall I say the past.
I used to own one of these in 1989.
Back then CD's were just starting to get popular and many cars did not have CD players.
The big thing about this thing was that it was "shock-proof." Compared to today it's pretty unsophisticated the cd spinner/reader was actually mounted on a shock absorber system and kinda float like a car suspension.
I don't think it had a memory buffer for anti skip. On big bumps it did skip, but I had a really small and hard-riding sports car then and I drove like a maniac (still do)
It's called CAR discman due to absorbtion system and because it came with a cassette tape output adapter and velcro strips to mount to the dash of your car.
From what I remember it wasn't bad. It also had a 1/8 mini lineout (full volume or adjustable I don't remember.
Good memories. I beat the $#%#& out of this thing physically caring it in and out of the car and basically throwing it in the back trunk so it wouldn't be seen and stolen. This thing was tough, and could really take some abuse and still work great, not like the plastic crap cd players today.
Ahhhh......Memory lane.
You made my day.
edit: It came with a DC power adapter also that went into the cigarette lighter.
edit2: I don't think mine had the DSP. I don't remember using it. (?) I used to use it with car stereo, sony earbuds, and my onkyo home stereo because my carousel couldn't read some CD's with silkscreened pictures on them. I can't say how it would compare soundwise to today's stuff. I do remember it was built like a tank.
