Mike - Your Rockwell looks to be a full size belt drive contractor saw. The 36-600 is more of a downsized compact contractor saw "look-a-alike" (only 22"d instead of 27"d, and is 38"w vs 40"+ of a full size saw). They weigh in ~ 150# vs 250# of a full size saw, and have a 15 amp universal motor. It later became the TS300 and retailed in the $300 range.
Depending on condition, it might be worth $100 or so, but they tend to be cost prohibitive to fix if the motor kicks the bucket. FWIW, my 36-600 did everything I asked of it...it was a little loud, and a little lightweight, but wasn't a bad saw.
