VTech Socrates Educational Video Game System 1988 Vintage Untested

Vintage VTech Socrates Game Console
Comes with everything seen here. Brand new batteries. The power cord is missing for the console but it is supposed to run on battery power alone.
Coax cable and HDMI to RF converter included.
I do not know if this works... I bought it because | had one as a kid and wanted my kids to have one. It didn\'t come with the power cord but you can order one online for pretty cheap I think.
I can\'t dig it not how to connect everything and how to get it working with our tv. Not sure if it\'s me or the console. The console and box look pretty nice though for a 40 year old item. Has original Target price sticker for $139.99!
