All-in-ones are generally called "compact systems". However, at 69cm x 48cm, the RPC650TP was far from being compact, sure - but so much more elegant !
It isn't the most lavish, nor the biggest, nor the most lit up but quite close enough. Inside this console are a 2x 50W power amp, a Dual 491 turntable, a digital PLL tuner with MPX and switchable AFC, a Grundig CN830TP cassette deck with Dolby and switchable AGC, bass, mids and treble controls, a 2-position contour, a 2-position high filter, 10 memory presets, a 3-position MM preamp, two headphones plugs, automatic fade in/out for recording, a 2nd output to record on another deck, a frequency/channel switchable display, and a multi-room capacity.
And all this, I repeat, all this being controllable by way of the TP650 infrared remote control.
Yes : start the LP, no, switch to radio, change the channel, adjust the mids a little, the bass too, ok, start recording, ooops -put the balance back to zero-, turn off the remote set of speakers and up the volume of the main speakers - without moving from your sofa.
And if all this efficient compactness isn't enough, you can always display the RPC650TP on its dedicated Drehfuss 5 so that it looks even more like a work of Art ready to be exhibited at the MOMA.
Perhaps bigger was the ITT HC9071 but this was from high-fidelity's peak year : 1977.
