Touch Me Babe!
Yes, I actually have this. It's a handheld game from 1978 and it plays like Simon. If you think it's a copy you would be wrong. Although both were released in 1978, Touch Me was in arcades 4 years earlier as a stand-up cabinet.
As with so many things I love, here is the manual scanned by me.
First day of classes is tomorrow, but my first one is at 4:15 pm so I'm not too worried about sleeping through.
