Okay, I've emailed my roommate who is still there and asked him to forward the M#.

It turns out it is a Technics SL-D2. The full name he forwarded is:
"Technics Direct Drive Auto Turntable System SL-D2"

It has an automatic tone arm that will return at the end of the side or when the stop button is pressed. It doesn't, however, automatically bring the tone arm to the start of the record like my dad's does (I'll post that model tomorrow, it's a nice one).

I couldn't find anything about the player online. Anyone else have more luck?
