Have a look at the attached pic... look familiar <G>? Hehe, prolly not for some of you "youngsters" in the forum <LOL>! That's a handheld LED football game by Mattel, circa 1978 -:) Back in my high-school days, everyone was playing with one of those.
Now, surf over to http://www.peterhirschberg.com/handheld/ledhead/windows_download.htm
and install the proggie there "LEDhead"... includes not only the game in the attached pic, but a slew of other Mattel handhelds from the late '70s and early '80s -:)http://www.peterhirschberg.com/handheld/ledhead/supportedgames.htm
