I made an assumption. I actually thought that he was referring to a 24LC, because given that the micro only has 18 pins -- it's impossible to directly interface it to a 27c without a 4040, 12-BIT, BCD counter (or similar) for the parallel addressing. Even then there would be insufficient IO pins remaining for the rest of the project. On top of that -- playing around with eproms isn't a chore for the beginner. Perhaps I'm totally mistaken.
