It was with a great deal of interest that I read the article in the May 1988 issue of Word Ways entitled "The Electronic Speller" by Faith Eckler. Soon after that I noticed the appearance of a device known as the Spelling Ace on top of a showcase in the Sight and Sound (Electronics) department at the store at which I am employed. After toying with it a number of time, my first notion was that "The Electronic Speller" described this gadget. Alas, it didn't, but I enjoyed her article anyway.
