That's either a 650 or 651 Theatre. Almost impossible to say from this pic. The 651 has an automatic rhythm unit in the lower left cheek block and the 650 doesn't. There are a few other differences but that's the clincher.
Neither are from 1980. The 650 ran from 1968 to 1973 and the 651 from 1973 to 1978.
Worth $700? In full working order, I'd pay the UK equivalent if I were after a 3-deck console.
Read through some of the Conn threads on this site for details on reliability issues etc. Converting it for MIDI has also been dealt with here and also over on the MidiTzer site at www.virtualorgan.com
Any idea why they called the organ a Rhapsody?

It's not what you play, it's not how you play. It's the fact that you're playing that counts.
