Last model year for Motorola-designed Quasar sets?

Hey Bryan:

What was the name of those Panasonic sets produced in the late 70's that used I believe 4 "pull-out" modules all lined up vertically on the chassis and used an SCR for a low volts regulator? I had one of these sets around 1983 and it had 3 piano keys in the front for power, AFT and something color. I remeber it was something like Quintracolor but cant be sure. Any ideas?
