It is the same as the ebay auction I am pretty sure; unfortunately I no longer have the boards. I bought them in the early 90's (90-91 era most likely) from all electronics. I still have the ULN2804's and 14 segment displays but the rest is long gone. I powered one up and it indeed played like an electronic scrabble game. You got your set of letters and had to form words, and it would score. Of course it couldn't check the "quality" (or lack thereof) of your words and would just score the letters you used.
