It looks like a customized build from a mini/portable reel to reel tape deck. There are similar ones out there, but without the joystick and the panels.
Wow thanks, that's certainly a point in the right direction :thumbsup It certainly looks like that one. The one used for the prop appears indeed to be a Panasonic, but the Panasonic RQ-156S has incorrect buttons :unsure
It's the Cybernaut control unit from The New Avengers. I believe after checking it out that Teslabe is right, it's the Penncrest Capstan Drive recorder. The labels were probably altered.
