Ok I found some related items and the first device looks like it is a baseball game / baseball card reader. Still no idea on the second one.
The second pic looks like a hardcore version of 'Simon' http://www.globaltoynews.com/2015/02/simon-says-thanks-ralph.html
Kind of wonder if it was some sort of simple game you could play with a friend over the phone line? It has the handset passthrough so your phone can still operate as a phone without disconnecting the device. Just conjecture.
