Sony EIAJ Color Portable AV8400
The introduction of the 8400 allowed color recording in a "portable" format.
The transport unit can record color from a camera or from a tuner (outboard) but can only
play back in monochrome unless connected to its AC1000 power supply containing the CLP-8000 color adapter.
When this machine was introduced color cameras were still *very* expensive,
so it is rare to find vintage live color tapes made with an 8400.
