How many pages are in the homework machine?

None, it"s a dramatic record album, not a book! Danny Dunn and the Homework Machine was the full title. last seen in a record dept. in a Great Eastern store around l972. nobody ever bought this stuff. from cover illustrations, the machine resembled a Linotype or maybe a very early centralized traffic control machine used to run and monitor, say, subway or RR signal operations. many flashing lights, etc. My guess the story came out in the fifties when computers were remote and somewhat exotic, not everyday appliances like this one being used at the library. It was not, by the way, called a computer.
