MisterM wrote this instructable detailing his 1981 portable VCR Raspberry PI media centre:
This is an early ’80s Sharp VC-2300H portable VCR that I’ve converted – it now has a Raspberry Pi at its heart, running the excellent Raspbmc media centre software. Other upgrades include a snazzy arduino-based clock and an EL wire “tape” that ejects to reveal the slots of a powered USB hub. The original buttons are used for various functions and it has an integrated 15″ HD screen at the back, with a clear access panel on the side showing off the Pi.
Check out the video after the break.
